Delta’s new electrically controlled barrier receives P1 rating at ASTM M50 test level
Delta’s new electrically controlled barrier receives P1 rating at ASTM M50 test level

Delta Scientific’s latest HD 300 barrier, is available with either a fully electric or hydraulic control unit, and will stop a 15,000 pound (66.7 Km) vehicle travelling 50 mph (80 kpm). Upon impact, the barrier remains in its foundation and the opening stays blocked, providing a multiple hit capability. In its M50 crash test, the HD300 completely disabled the test vehicle, causing severe damage to the occupant department and power train. The maximum penetration recorded was an outstanding -1.8 m on the passenger’s side. The P1 penetration rating was given because the penetration beyond the protected side of the barrier was less than 1.0 m at the lower leading edge of the test vehicle’s cargo bed. “The HD300 provides many of the flexibilities that security professionals want in a vehicle access barrier,” explains Greg Hamm, Delta Scientific vice president, marketing and sales. “Besides being easy to install and providing a fast emergency fast operation, low maintenance and multiple hit capabilities, customers can select either our new all electric control unit or Delta’s lauded hydraulic control unit.”With its 24-inch (61 cm) shallow foundation and aesthetic design, the HD300 obviates the concerns of interference with buried pipes, power lines and fibre optic communication lines. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. The HD300 is perfect for high water table locations and areas with corrosive soils. It provides low maintenance as all components are accessible from the sides or top of the barrier.For increased security, the HD300 leverages Delta’s propriety counter-balanced technology to provide a 1.5 second emergency fast operation (EFO), responding to attacks very quickly. The electric actuator provides IP67 protection, meaning that the unit is totally protected against dust and as well as the effect of immersion between 15 cm and 1 m.

Delta Scientific DSC1500 Beam Barricade
Delta Scientific DSC1500 Beam Barricade

The new DSC1500 portable beam barricade sets up quickly and temporarily to block vehicles and secure locations during short-term events and anywhere a beam barricade is needed for interim security. With a clear opening of 16 feet (4.8 m), the DSC1500 is M30 certified, able to stop a 15,000 pound (66.7 kN) vehicle going 30 mph (48 kph). Many organisations have the need for easy to install, temporary drop-arm barriers that can install within 10 minutes to transitorily close down a roadway to one or two lanes or block parking lot exits to deter thefts. Previous beam barriers had to be filled with sand, gravel or cement to be operable. To remove the DSC1500 from its temporary site, it is simply repacked in ten (10) minutes. No excavation or sub-surface preparation is required. Once positioned, the mobile barricades unpack themselves using manual hydraulics to raise and lower the barriers off their wheels. A self-deploying trailer with integrated lifting device facilitates rapid installation. The process is simply reversed when the event is over or the time comes to deploy the beam barrier at another location. From a purchasing standpoint, it can be easier to buy portable beam barricades than permanent solutions. The latter are oftentimes placed into an organisation’s real assets budget because they are permanently installed into the ground, becoming part of the property. Such budgets can often create complex purchasing scenarios for law enforcement or public safety departments. However, purchasing portable beam barricades is no different than buying protective vests for personnel or new sets of wrenches for the maintenance department. For one time uses, a lease plan has been created where organisations can simply lease the portable barriers, use them, pack them up and return them. Delta always keeps an inventory for purchase and quick delivery at their manufacturing facility in Palmdale, Calif. That’s because, in many cases, they are needed for events that come up quickly, such as emergency road or bridge construction or unexpected parking lot requirements.

Delta Scientific HD200 vehicle barrier for high traffic locations
Delta Scientific HD200 vehicle barrier for high traffic locations

The fastest operating standard vehicle barrier in the market, the HD200 features a crash rating of ASTM M30/P1, bringing to a full stop a 7.5 ton (6803.9 kg) medium duty truck traveling 30 mph (48.3 kph) in less than 3.3 feet (1 m). Truck rebound is 11.5 feet (3.5 m).Final denial applications Built for high traffic, heavily populated locations requiring rapid emergency fast operation (EFO) rates and open/close cycles, in high traffic locations, the barrier is open much of the time, letting vehicles through. Therefore, when the location is heavily populated, the barrier must open and close frequently. More importantly, the barrier must be able to close quickly. To negate vehicles being used as weapons, the HD200 barrier will stop and destroy a vehicle moving at 30 mph (48.3 kph). This allows users to install this barrier in final denial applications with as little as 50 feet (15.2m) of stand-off distance and still stop vehicles moving up to 44 feet (13.4 m) per second. Increased safety against terrorists using vehicles as weaponsAs the tragedy in Nice, France, has warned, security professionals need to be aware of vehicle attacks on people. For heavy traffic in densely populated locations, not only must the vehicle barrier be fast but it must be rugged and easy to install.The HD200 provides the features needed in a vehicle access barrier. Besides being easy to install and providing a quick emergency fast operation and low maintenance, customers can select either Delta's new all electric control unit or Delta’s lauded hydraulic control unit. With either, the HD200 barrier will stop a 7.5 ton (6803.9 kg) medium duty truck travelling 30 mph (48.3 kph) in less than 3.3 feet (1 m).With a 24-inch (61 cm) shallow foundation and fully enclosed, flush mount design, the HD200 obviates the concerns of interference with buried pipes, power lines and fibre optic communication lines in urban applications. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. The HD200 is perfect for high water table locations and areas with corrosive soils. It provides low maintenance as its totally enclosed face is easily removed for access. Remotely controlled EFOLeveraging the latest technologies, the HD200’s breakthrough EFO can be remotely controlled via fibre optics, touch screen control panels, NEMA rated control button panels and simple key switches.The HD200 barrier also features a full range of diagnostic indicators for early detection of any difficulties.As with most other Delta barricades and barriers that are properly maintained, projected life expectancy of the HD200 is 20+ years.

Delta’s newest EM-controlled anti-terrorist crash barrier provides less than zero penetration
Delta’s newest EM-controlled anti-terrorist crash barrier provides less than zero penetration

Delta Scientific, the leading manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, recently announced that its new HD2055 electromechanically controlled anti-terrorist barricade decisively stopped the 15,000 pound (6,803 kg) test vehicle traveling at 51 (82 kph) in a recent crash test conducted by an independent testing laboratory. Less than zero penetration of crash barrier The HD2055 barricades not only stopped the vehicle but contained the test load representing the bombs strapped to the truck bed. The crash test result showed a less than zero penetration. “Significantly, the operating mechanism and cams were all intact and reusable after the dramatic crash test,” emphasises David Dickinson, Senior Vice President of Delta Scientific. “This level of survival is normally only seen with hydraulic barricade systems.” Easy-to-install shallow foundation The new HD2055 barricade features an easy-to-install shallow foundation with an environmentally-friendly electromechanical actuator which utilises a sophisticated cam design that accelerates and de-accelerates the barrier road plate during raising and lowering. This reduces the lifting and closing force down to zero at the end of each stroke, dramatically increasing the life of the lifting mechanism. The shallow foundation also obviates the concerns of interference with buried pipes, power lines and fibre optic communication lines. The HD2055 is perfect for high water table locations and areas with corrosive soils. It provides low maintenance as all components are accessible from the sides or top of the barrier. As with its hydraulic designs, the electromechanical HD2055 can be deployed as a single barricade in a narrow lane application or in extended arrays which cover wide roadways. Each HD2055 barricade can be open or closed individually or as a group to allow the passage of both small or large vehicles. Like other Delta Scientific products, the HD2055 can be remotely controlled via fibre optics, touch screen control panels, NEMA rated control button panels and simple key switches.

Delta DSC7090 Beam Barricade

Delta Scientific's new bolt down DSC7090 beam barricade has passed its crash test garnering an ASTM M30/P1 rating. That means the DSC7090 will stop a 15,000 pound (6800 kg) truck going 30 mph (50 kph) with negative 6.3 feet (1.9 metres) of penetration. Raising in only five seconds and lowering in merely two seconds yields a fast cycle rate of over 100 vehicles in and out per hour, making the new DSC7090  ideal for higher traffic and population locations. The dual beam design provides coverage of 12 to 24 feet (3.7 to 7.3 metres) of roadway with a full 90 degree opening. The DSC7090 beam barrier crash test is the culmination of one of a series of new products that Delta will be bringing to market. Full scale crash testing provides unequivocal proof of the stopping capacity of each of Delta's vehicle barricade designs. To date, Delta Scientific has conducted 67 full crash tests with more scheduled. That's another way in which Delta Scientific can commit to providing safety and security through product innovation. The new DSC7090 will be used in locations where wide roadways need to be secured from attacking vehicles and in larger parking areas where security systems are needed to deter theft. To meet these heightened demands, the DSC7090 deploys sophisticated touch screen controls and the same logic as used by key government organizations. This includes an LED light package with traffic lights. Also available is a strobe light and audible alarm package. The DSC7090 operates remotely by means of an integral hydraulic pumping unit (HPU) that is buttress enclosed. The HPU can be powered from a local single or three-phase power source. Alternative power options are also available.

How schools can make outdoor learning safe and secure
How schools can make outdoor learning safe and secure

Schools were never designed and built with social distancing in mind. So it’s perhaps not surprising that as children returned to schools for the autumn term this year, the prospect of outdoor classes and assemblies was mooted in the media and by the Government. Many in the education sector are making the case that, should there be further COVID-19 outbreaks, in the coming months, it would be better to utilise outside space, rather than resort to closing schools. In the COVID-19 era, head teachers are considering taking learning and large gatherings, such as assemblies outdoors, when possible. Managing ‘class bubbles’, hygiene and ventilation While Dr. Yvonne Doyle, the Medical Director of Public Health England (PHE) has publicly reassured parents that schools are not the ‘drivers’ or ‘hubs’ of COVID-19-19 infection in communities, there is a lot of pressure on school leaders to manage ‘class bubbles’, extra cleaning and hygiene, ventilation, and COVID-19 testing, to protect families and staff. It’s a logical step to switch, in certain circumstances, to outdoor activities where fresh air is on tap, and social distancing is far easier to manage. Specially built outdoor classrooms Across the school and nursery sector, there’s ongoing investment in specially built outdoor classrooms Across the school and nursery sector, there’s ongoing investment in specially built outdoor classrooms, which had been growing in popularity, even before the pandemic. These facilities offer numerous benefits as an extension of existing learning spaces and provide children the opportunity for hands-on learning, beyond a stuffy classroom. However, if outdoor spaces are routinely called upon as part of COVID-19 contingency planning, how can schools ensure that their outdoor classrooms and wider areas are secure, robust, and fit for purpose? When specifying outdoor classrooms and learning spaces, it’s essential to take into account the well-being of the students and staff, who will use them, noise pollution and acoustics. Most importantly, education managers need to ensure the surrounding area is secured and adequately protected from threats, including terrorism. Perimeter security measures for schools How can schools and nurseries secure their perimeters, so that outdoor learning is totally safe for all? A starting point is to seek out architects and suppliers, who have a good understanding of security standards. Worryingly, Jacksons Fencing’s research recently found that only one-third of architects are seeing both LPS 1175 and the UK police initiative, Secured by Design (SBD) physical security standards, specified for schools. This highlights a lost opportunity for architects to propose solutions that are appropriate to the level of risk and needs of the school, without turning the site into an unwelcoming fortress. Helping schools identify specific security needs Head teachers would be wise to work with architects, who not only know the latest security standards inside and out, but are also are willing to play a more advisory role, helping the school identify exactly what is needed. Head teachers should prioritise solutions appropriate to their site’s specific risks It’s also vital that architects don’t simply replace existing fencing and gates, with the same security systems that have been in place for years. Instead, they will need to meet changing needs and risks. Our research finds that teachers often report issues, with the school perimeter and gates, from being climbed over (28%) and causing injury, to gates not locking properly (10%). Head teachers should prioritise solutions appropriate to their site’s specific risks, which sometimes require altering of existing measures. School fencing is an important aspect of any education site. As well as defining its boundary and making a visual distinction between public and private property, the fencing and gates that surround and secure a school, will typically meet a wide variety of other important criteria, including preventing unauthorised entry to the grounds, protecting pupils, staff, and visitors from accidents and injury, deterring theft and anti-social behaviour, and reducing the risk of malicious damage, and acts of terrorism. Welded mesh panels for perimeter fencing Popular options for schools include welded mesh panels for perimeter fencing or sports areas, and railing systems to act as demarcation, in order to control foot and car traffic. Within the outlying boundary, barriers, bollards and parking posts will keep pedestrians, and vehicles safe from each other, while timber fencing and gates can be designed to control the flow of people, around the grounds and reduce the areas, where students can be hidden from view. Automated gates and access control Perimeter fencing must be complemented with safe entrances and exits for vehicles and pedestrians. Every school has unique entry-control requirements, determined by factors, such as size, location and the local environment. These needs influence the decisions you make, when preparing technical specifications for school security gates. Do you require gates to be steel or timber, manual or automated, single or double leaf? Specialist suppliers will be in the best position to offer inputs on school gates, which typically need to offer solid security and durability, with a welcoming aesthetic. Specifying access control system When specifying a school access system, it’s important to consider the areas of the school When specifying a school access system, it’s important to consider the areas of the school, such as sports fields, car parks, and children’s play and learning areas, and whether it requires playground segregation. Selected gates should meet the design of the fencing, to create a secure perimeter with no weak points, with automated gates conforming to all current safety regulations. . Noise pollution can be a problem as well, including noise coming in or leaving the school in residential areas. If more teaching is to be carried out outside, it’s worth considering acoustic barriers to reduce noise in and around the school. Timber acoustic barriers for security and privacy Timber acoustic barriers offer security and privacy, and can reduce noise levels, by as much as 32 decibels (in laboratory conditions), so are ideal for city centre schools or those located close to busy highways. There are many ways to build an outdoor classroom. Timber products can help to create a welcoming environment, such as wooden shelters, pergolas, fencing, and decking. Always check that high quality timber, ideally guaranteed for 25 years against rot and insect attack, is being used to provide an attractive, cost-effective, safe and sustainable solution, for all weather conditions. DBS approved installers And of course, installers must be DBS approved, so that they can install outdoor classrooms, during school holidays, or within term time, with minimal disruption. The COVID-19 pandemic had a huge impact on schools and learning. While nobody wants to think of fresh outbreaks of the infection, or any other virus, installing an outdoor classroom made from high-quality, long-lasting materials is a great way to future-proof school learning and ensure safety, and preparedness. Putting extra thought and care into the security angle will provide schools with decades of protection against a host of unforeseen events.

The physical side of data protection
The physical side of data protection

The impact of the COVID-19 pandemic has accentuated our digital dependency, on a global scale. Data centres have become even more critical to modern society. The processing and storage of information underpin the economy, characterised by a consistent increase in the volume of data and applications, and reliance upon the internet and IT services. Data centres classed as CNI As such, they are now classed as Critical National Infrastructure (CNI) and sit under the protection of the National Cyber Security Centre (NCSC), and the Centre for the Protection of National Infrastructure (CPNI). As land continues to surge in value, data centre operators are often limited for choice, on where they place their sites and are increasingly forced to consider developed areas, close to other infrastructures, such as housing or industrial sites. Complex security needs One misconception when it comes to data centres is that physical security is straightforward One misconception when it comes to data centres is that physical security is straightforward. However, in practice, things are far more complex. On top of protecting the external perimeter, thought must also be given to factors, such as access control, hostile vehicle mitigation (HVM), protecting power infrastructure, as well as standby generators and localising security devices to operate independently of the main data centre. Face value How a site looks is more important than you may think. Specify security that appears too hostile risks blatantly advertising that you’re protecting a valuable target, ironically making it more interesting to opportunistic intruders. The heightened security that we recommend to clients for these types of sites, include 4 m high-security fences, coils of razor wire, CCTV, and floodlighting. When used together in an integrated approach, it’s easy to see how they make the site appear hostile against its surroundings. However, it must appear secure enough to give the client peace of mind that the site is adequately protected. Getting the balance right is crucial. So, how do you balance security, acoustics and aesthetics harmoniously? Security comes first These are essential facilities and as a result, they require appropriate security investment. Cutting corners leads to a greater long-term expense and increases the likelihood of highly disruptive attacks. Checkpoints Fortunately, guidance is available through independent accreditations and certifications, such as the Loss Prevention Certification Board’s (LPCB) LPS 1175 ratings, the PAS 68 HVM rating, CPNI approval, and the police initiative - Secured by Design (SBD). Thorough technical evaluation and quality audit These bodies employ thorough technical evaluation work and rigorous quality audit processes to ensure products deliver proven levels of protection. With untested security measures, you will not know whether a product works until an attack occurs. Specifying products accredited by established bodies removes this concern. High maintenance Simply installing security measures and hoping for the best will not guarantee 24/7 protection. Just as you would keep computer software and hardware updated, to provide the best level of protection for the data, physical security also needs to be well-maintained, in order to ensure it is providing optimum performance. Importance of testing physical security parameters Inspecting the fence line may seem obvious and straightforward, but it needs to be done regularly. From our experience, this is something that is frequently overlooked. The research we conducted revealed that 63% of companies never test their physical security. They should check the perimeter on both sides and look for any attempted breaches. Foliage, weather conditions or topography changes can also affect security integrity. Companies should also check all fixtures and fittings, looking for damage and corrosion, and clear any litter and debris away. Accessibility When considering access control, speed gates offer an excellent solution for data centres. How quickly a gate can open and close is essential, especially when access to the site is restricted. The consequences of access control equipment failing can be extremely serious, far over a minor irritation or inconvenience. Vehicle and pedestrian barriers, especially if automated, require special attention to maintain effective security and efficiency. Volume control Data centres don’t generally make the best neighbours. The noise created from their 24-hour operation can be considerable. HVAC systems, event-triggered security and fire alarms, HV substations, and vehicle traffic can quickly become unbearable for residents. Secure and soundproof perimeter As well as having excellent noise-reducing properties, timber is also a robust material for security fencing So, how do you create a secure and soundproof perimeter? Fortunately, through LPS 1175 certification and CPNI approval, it is possible to combine high-security performance and up to 28dB of noise reduction capabilities. As well as having excellent noise-reducing properties, timber is also a robust material for security fencing. Seamlessly locking thick timber boards create a flat face, making climbing difficult and the solid boards prevent lines of sight into the facility. For extra protection, steel mesh can either be added to one side of the fence or sandwiched between the timber boards, making it extremely difficult to break through. A fair façade A high-security timber fence can be both, aesthetically pleasing and disguise its security credentials. Its pleasant natural façade provides a foil to the stern steel bars and mesh, often seen with other high-security solutions. Of course, it’s still important that fencing serves its primary purposes, so make sure you refer to certifications, to establish a product’s security and acoustic performance. Better protected The value of data cannot be overstated. A breach can have severe consequences for public safety and the economy, leading to serious national security implications. Countering varied security threats Data centres are faced with an incredibly diverse range of threats, including activism, sabotage, trespass, and terrorism on a daily basis. It’s no wonder the government has taken an active role in assisting with their protection through the medium of the CPNI and NCSC. By working with government bodies such as the CPNI and certification boards like the LPCB, specifiers can access a vault of useful knowledge and advice. This will guide them to effective and quality products that are appropriate for their specific site in question, ensuring it’s kept safe and secure.

Key considerations for robust residential security
Key considerations for robust residential security

In the UK, one burglary occurs every 106 seconds. This means by the time you've finished reading this article, at least three will have taken place. Selecting robust physical security options to protect property boundaries and homes is essential to limit crime rates and deter opportunistic intruders. With 58% of burglaries said to take place while the homeowner is in, it seems that even the second wave of lockdowns, and an increased number of people confined to their homes, won't do much to eliminate the risk of burglary. Prioritise security for peace of mind Security is paramount, and in the case of new build projects, should be considered from the very beginning of the design process, not as an afterthought. When it comes to securing pre-existing buildings, there are countless security options which will ensure the perimeter is robust enough to withstand opportunistic attacks. It's also worth noting that security features don't have to be complicated. There are plenty of high-tech digital systems flooding the market, which can go a long way to reduce the risk of burglary and will provide peace of mind to the end user. However, this article will demonstrate how traditional security measures, such as high-quality perimeter fencing, can ensure practical safeguarding of properties for years to come.  Selecting robust physical security options to protect property boundaries and homes is essential to limit crime rates Timber! There are a number of different materials which can be specified to create a strong boundary. From metal railings, to timber fence panels, they will each help deter criminals somewhat. Wooden fence panels are a popular choice for their appearance, and the right product and installation can help to increase security.Our timber acoustic fencing can also reduce noise by up to 32dB and has a solid face with no hand or footholds, while still retaining the attractive natural timber aesthetic of a typical garden fence. However, maintenance is key, and one of the first thing burglars will notice is the condition a fence is in, rather than a particular style. Therefore, old, broken or rotten fence panels are a green light for opportunistic thieves. These can be easily broken or bypassed with minimal effort. When specifying fences as part of a new build housing development, we would suggest opting for high-quality timber, as this will ensure that it is protected against rot. Look for products with an extended guarantee or those that don't need additional treatment over the years. The condition of the fence should still be regularly inspected, and simple methods such as clearing piles of leaves away from the base of the boundary can help to prevent rot which weakens the timber.  Securing fence panels The recent rising cost of timber has led to a dramatic increase in fence panel theft, and panels that can be lifted from the posts are an easy target. Mitigate this risk by screwing the fence panels into the posts. This makes it much harder for the panels to be removed from the posts and creates a more secure barrier.  Concrete posts do offer benefits, but we always advise on timber posts for any fencing. They're strong, just like concrete, but they continue the same natural theme as the rest of the fence. Moreover, if you screwed the panels to concrete posts, they would most likely crack and become damaged, and then be at risk to the elements.  Astute design Design is also important. Installing fence rails on the inside of properties to prevent them from being used as climbing aids is highly recommended. Even better, using panels without rails on high-end developments is a clever tip if you want a secure fence with a high-spec look. Security features don't have to be complicated High fences with solid panels and no gaps in between make it considerably harder for potential burglars to climb over. They also offer better privacy to conceal rear garden areas from intruders, and are much sturdier than other alternative panels.  One common mistake is designing in features such as trees or children's climbing frames too close to the boundary. These can be used by burglars as climbing aids when attempting to scale the fence, making access easy. Investigate the surrounding area, which flanks the outside of the property boundary, as an unfortunately placed bin or bench can also help criminals gain entry. If the removal of these items is not possible, designing in a spiky bush can help deter intruders. It's also worth noting that gardens with numerous large features such as bushes or sheds can also negatively impact the level of security. A clear line of sight across the entire garden is highly recommended where possible. If this view is blocked, it's considerably easy for intruders to hide undetected. Front gardens  While tall, solid fence panels are recommended for rear gardens to prevent intruders from being able to see in and climb over, the opposite is true for front gardens. For street-facing gardens, a low fence or hedge is recommended to provide a clear view from the house. It also makes it much harder for intruders to hide from passers-by or neighbours, who can raise the alarm during a burglary. Another useful security technique to consider is a gravel drive. These create noise, which means the homeowner will know when it is in use. Pair this with a strong boundary fence, the likelihood of burglary dramatically decreases. This article only scratches the surface in unveiling the sheer volume of effective home security options on offer to protect homes and gardens. These investments can help minimise the risk of traumatic break-ins, while also simultaneously boosting the aesthetic of the property and its surroundings.

Delta provides crash rated gates to enhance security at the Los Angeles International Airport
Delta provides crash rated gates to enhance security at the Los Angeles International Airport

The Nation’s Seaports and Airports throughput thousands of people and billions of dollars worth of materials every day. These ports comprise of massive plots of land located amongst densely populated communities. Seaports can see throughput of more than a thousand trucks on any given day, while airports need to accommodate often erratic traffic consisting of support vehicles, fire trucks and heavy equipment. Securing these facilities requires a varied combination of crash rated barriers. At locations where restricting access of passersby is just as important as stopping unwanted vehicles, crash rated gates are the best option. Los Angeles International Airport has used a variety of Delta Crash rated gates to protect fuel depots, hangers and runways. Access control devices In-ground wedge barriers have found favour at port roadways, allowing security personnel to screen trucks entering and exiting the port. Delta Scientific has worked with more than one hundred port locations to design the barrier system that best meets the demands of the facility. Airports across the nation are now taking measures to protect everyone, passengers and employees Though every effort is made to ensure the safety of air travellers, what is being done to protect those that work within the airports? What about the security of the cargo delivered? What about perimeter security breaches – allowing possibly dangerous terrorists and criminals onto federal aviation property, thereby endangering everyone within? Airports across the nation are now taking measures to protect everyone, passengers and employees, by installing vehicle access control devices. These new airport security systems are designed to stop anyone from driving any type of vehicle. Controlling vehicle access Originally used primarily to stop the constant risk of thefts at car rental agencies, bollards, barriers, barricades and crash gates are now common throughout airports, especially after 9-11. Booths were traditionally used for housing guards who collected parking fees. They’re often ballistic rated. From protecting the tarmac to passenger areas, airports today are especially conscious of controlling vehicle access. As a countermeasure to the increased theft of rental cars throughout the nation approximately 15 years ago, many rental car operators began using traffic controllers to disable unauthorised vehicles from entering or leaving their lots. Installation of these units all but eliminates drive or crash out thefts. Over 120 other car rental lots throughout the nation have installed some variety vehicle access control systems. Motorised traffic controllers The rounded corners and custom painted design complement their two 9-level parking structures The motorised traffic controllers (the ‘wrong-way’ teeth), warning signs and traffic and surface mounted controllers (i.e. gates) together prevent thefts of rental cars by disabling unauthorised vehicles from entering or leaving the lot. Almost every airport features parking/cashier booths. Some are fairly basic; others are upgraded. For instance, on the way out of the Minneapolis/St. Paul International Airport 18 prefabricated Delta parking/cashier booths help handle the airport’s doubled parking capacity of 13,000 spaces. Put in prior to 9-11, these booths are simultaneously aesthetically pleasing and contribute to the overall security of the airport by providing vehicle access control. The rounded corners and custom-painted design complement their two 9-level parking structures. Two heaters, double insulation and tinted glass help parking attendants to guard against both the Minnesota winters and sun. Increased security measures Contrast them with the bullet-resistant level 4 booths used at California’s Ontario Airport. These 6 x 12-foot buildings were manufactured to meet tight specification requirements, including structural calculations and wet seals from drawings by a Registered California Structural Engineer. Such barricades can be raised or lowered at will to stop traffic or let it through The ramp-up in guard booths illustrates the increased security measures airports now take with vehicle control. Soon after 9-11, the United States Air Force began deploying very high-security DSC501 barriers at its facilities around the globe. The DSC501 barricade will stop and destroy a 65,000 lb. vehicle traveling 50 mph. Such barricades can be raised or lowered at will to stop traffic or let it through. In an emergency, the thick steel plates or bollards pop out of the ground within 1.5 seconds. Commercial airports followed suit. Optic communication lines This barricade was originally designed for the U.S. Navy and has also been selected for use at U.S. Embassies. Set in a foundation only 18 inches deep, the Delta DSC501 is able to survive after a 5.4 million foot-pound impact. With its shallow foundation, it obviates the concerns of interference with buried pipes, power lines, and fibre optic communication lines, a major consideration at airports. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. Front face warning lights warn drivers that the barricade is in the ‘up’ position. There is also an open area on the front for signage. Diagonal yellow and white stripes are standard and optional colours and graphics are available. The open channel construction even lets airports specify hot dip galvanising. Securing access points The sliding gate system that is used in such an application must be crash rated Among the many FAA mandates airports must meet is one that requires securing access points to international freight lines. That includes access to air cargo facilities, where scores of trucks must go in and out on an hourly basis. That was the issue facing California’s largest fencing contractor, Alcorn Fence, at Los Angeles International Airport (LAX) for Qantas and Singapore Airlines. The sliding gate system that is used in such an application must be crash rated. Clear openings range from 12 to 30 feet. A linear crash gate will withstand the impact of a 15,000 lb vehicle striking the gate at 50 mph. To solve the problem, Alcorn Fence installed crash-tested swing gates on the runway that accesses the cargo facilities. Minimising installation costs The SCG1000 provides openings of up to 40 feet and the gates can be up to nine feet tall. Best of all no ground tracks are required, keeping installation costs to a minimum while protecting the integrity of the runway. These gates can be seen at LAX on the runway accessing the Singapore Airlines and Qantas Airlines terminals. This gate, like the SGC 1000, doesn't need a track, wheels or roller path across the entrance LAX additionally uses the SC3000 industrial gate in various places. This gate, like the SGC 1000, doesn't need a track, wheels, or roller path across the entrance or drive it protects. Thus, it adapts well to roads with high crowns, drainage gutters or other conditions that preclude ground tracks. Creating secure environments Aesthetics should not be overlooked. With smart designs, it's no longer necessary to choose between form and function. Airports can have them both. Designers are creating secure environments with more compatible and aesthetically pleasing architectural elements. With bollards, airports can create the look they want. Ranging from faceted, fluted, tapered, rings and ripples, colours, pillars, to shields, emblems and logos, bollards are aesthetically pleasing and versatile. In other words, they dress up airport security. Bollard systems operate individually or in groups of up to ten and are used for intermediate-level security applications. Individual bollards are up to 13.25 inches in diameter, up to 35 inches high and are usually mounted on 3-foot centres. Hydraulic and pneumatic versions can be operated by a variety of control systems. Manual versions are counter balanced and lock in the up or down position. Crash-resistant device All models are crash rated and lower to allow passage of authorised vehicles All models are crash rated and lower to allow passage of authorised vehicles. The incident at Glasgow International Airport raised new concerns for airports. The airport was evacuated after a green Jeep Cherokee struck the airport's terminal building and burst into flames. In such cases, a cost-effective fixed bollard array can be used instead of retractable bollards. However, airport infrastructures exacerbate installation problems caused by rough surfaces, turns, and lack of traditional foundation depth due to subsurface utilities and fibre optics, among others. Moreover, conventional barriers require surface areas to be completely level. Given the growing demand for a crash-resistant device that is easy to install, attractive, yet compliant with restrictive subsurface conditions, the DSC 600 Shallow Foundation Bollard was recently introduced. Unauthorised vehicle intruders Traditionally on curves, setbacks often end up too close to the facility. Now, airports can install bollards on the upper levels of parking structures and other unprotected facilities without using unsightly ‘make-do’ solutions to stop car bombers or negligent drivers. New DSC 600 Shallow Foundation Bollards will protect approaches to airport facilities New DSC 600 Shallow Foundation Bollards will protect approaches to airport facilities, drop-off and passenger loading areas at transportation hubs and other presently unprotected locations where unauthorised vehicle intruders have no obstacles to stop them. With the DSC 600 bollard modules, those facilities surrounded by streets, abutting sidewalks and set back on lawns can now be effectively protected. The new DSC 600 bollards will blend into curves, rough terrain or inclines easily. Setbacks can be as short as two feet, providing a much greater safety cushion for the airport facility. High-energy stops With a foundation only 14 inches deep versus the four feet typically required, Shallow Foundation Bollards can be installed within sidewalks, on top of concrete deck truss bridges or in planters as well as conform to the inclines and turns of a locale. The new 2-bollard modules, which can be arrayed in whatever length is required, will stop and destroy a 15,000-pound truck traveling 50 miles per hour. They have already successfully passed a K12 rating crash test, providing proof of their ability to provide high-energy stops. In fact, the DSC 600 is the first Shallow Foundation Bollard to successfully meet the U.S. Department of State Specification, Revision A that requires the bed of the attacking truck to go less than 39 inches beyond the point of impact. Total kinetic energy If the speed is reduced by 2/3rds, the force of impact will be reduced by nine times The new bollard modules also meet the 1-meter clearance regulations mandated by the Americans with Disabilities Act (ADA). Although the DSC 600 bollards will let people pass through them, they will stop vehicles dead in their tracks. Because of the relationship of velocity to the total kinetic energy possessed by a vehicle, airports typically force a vehicle to slow down before it reaches the bollard, or any other barrier in fact. The most frequently used technique is to require a sharp turn immediately in front of the barrier. When vehicle speed is reduced by 50 percent, the ‘hitting power’ is reduced by four times. If the speed is reduced by 2/3rds, the force of impact will be reduced by nine times. Reducing security risks Upon designing a way to slow down vehicle approach, they also assure that the attacking car cannot make a ‘corner cutting shot’ at a barricade. Often, only a light post defines a turning point and a speeding car can take it out and not even hesitate. Knolls and other impediments are typically employed. By their very nature, terrorist attacks are unpredictable and predicated on surprise. Staying one step ahead by identifying vulnerable areas, and securing them, is critical to staving off vehicular attacks. Terrorists typically don't go where they see barricades, so placing them wherever possible attacks can happen reduces security risks dramatically.

Delta Scientific’s DSC633 and DSC635 shallow foundation bollards help stop simulated bomb trucks at critical infrastructure sites

As the need for counter terrorist devices grew, Delta Scientific Corporation (Delta Scientific) answered the call and began building and crash testing barriers that would stop an attacking vehicle, allowing no infiltration to the premises. Over the years, Delta Scientific has designed, patented and crash tested numerous barriers, to meet the needs of specific government agencies and facilities. Collaboration with US agencies Over the last few decades, Delta Scientific has worked with many branches of the government, including all branches of the US Military, Department of Defense (DOD), Department of Homeland Security (DHS), Department of State (DOS), Department of Overseas Building Operations, Pentagon Force Protection Agency, Federal Bureau of Investigation (FBI), Department of Water and Power, Department of Veteran Affairs and the US Center for Disease Control (US CDC), along with municipal, county and state government agencies. The United States of America has repeatedly entrusted Delta Scientific to build the right crash rated barrier solution for critical infrastructure and to protect the nation’s citizens, in the service of their country. DSC633 and DSC635 single shallow foundation bollards DSC633 and DSC635 single shallow foundation bollards provide the highest level of protection against a vehicle attack Delta Scientific’s new patent pending DSC633 and DSC635 single shallow foundation bollards provide the highest level of protection against a vehicle attack. Tested to the new F2656-20 ASTM M30 and M50 standards, these new bollards provide the stopping power needed for modern threats. With a shallow foundation of only 24 inches (60.96 cm) and the ability to have single units, both bollards offer the flexibility and ease of installation, so as to cater to perimeter security needs. DSC630 Series bollards  Quite often, just stopping the bomb-laden truck is not enough. If the explosives in the truck detonate, all can be lost, irrespective of whether the truck was brought to a halt or not. The Delta DSC630 Series bollards feature static and dynamic penetration levels that hinder bomb loads to be moved, while still stopping the threats that they pose. Tested and proven to not only stop but also destroy the vehicle, Delta’s DSC630 Series bollards will keep a vehicle from repeatedly trying to breach the perimeter. The DSC635 bollard has a height of 44 inches (111 cm) and a diameter of 15.75 inches (40 cm) with a cover. Furnished with an array of decorative covers The DSC633 bollard has a height of 44 inches (111 cm) and a diameter of 13.75 in (35 cm) with a cover. Delta Scientific’s bollards can be furnished with an array of decorative covers, in order to enhance the look and match the aesthetic of the surrounding structures. These covers include stainless steel, powder coated aluminum, and fiberglass, with custom styling and painting also available. Lights, beacons, and audible devices can be added to the bollards for additional safety protocols. Shallow foundation bollards Delta’s shallow foundation bollards are often used to protect building perimeters and sports stadiums Delta Scientific has been manufacturing shallow foundation bollards and barricades in 24 inches (60.96 cm) or less height for decades. Shallow foundation bollards are the perfect solution for sidewalks, campuses, parking structures and government buildings, and corporate facility perimeters, where underground utilities and space limitations pose a problem for traditional deep foundation bollards. Delta’s shallow foundation bollards are often used to protect building perimeters and sports stadiums, as static arrays and used in conjunction with Delta’s active bollards and vehicle barricades, at entrances and exits. Delta Scientific Corporation is a worldwide renowned manufacturer of vehicle access control equipment, with over 260,000 square feet of production facilities in Palmdale, California. Delta’s three product lines consist of high-security vehicle barricade systems, parking control equipment, and guard booths.

Delta Security at the World’s Busiest Places

From airports to embassies, from warehouses to depots, Delta crash-rated gates stop unauthorised pedestrians and vehicles from entering places that they don't belong. Some models operate without contact with the ground across the opening, one is a manually operated swing gate and others operate with rack and pinion drives across V-groove wheel ground tracks while incorporating IR safety beam and safety edges. Swing versions are also available. The clear openings range from 12 to 30 feet (3,657 mm to 9,144 mm). The standard height for all, except the swing gate, is 109 inches (2,769 mm). There are five different models to choose from, assuring that any facility can incorporate a gate that will definitively meet its security demands. TT280: Exceeds every known  standard  The TT280 Linear Crash Gate withstands the impact of a 15,000 lb (66.7 km) vehicle striking the gate at 50 mph (80 kph), suffering no significant damage. The TT280 was created for the highest security applications such as embassies, government facilities, and corporate headquarters. The gate can be tailored to match the surrounding decor in a wide variety of architectural treatments. TT280 Linear Crash Gate withstands the impact of a 15,000 lb vehicle striking the gate at 50 mph The TT280 has been tested three times in full-scale configuration, each test at a successfully higher energy level, using the same gate, buttress, and foundation without any structural repairs or changes between tests. The gate met the test criteria in each case. Standard sizes are 108 inches (2.74 m) high and 144 inches (3.65 m) long. Clear openings of up to 33 feet (10 m) may be specified. SC3000S: High-security cantilever gate The SC3000S high security, the rolling gate is ideal for installations that need rugged performance. This gate will stop a 5,000 lb vehicle traveling 50 mph. The gates are fully cantilevered with no road track or overhead support. The gate leaf is supported by the main buttress at all times. When the gate system is closed, the gate leaf is locked into both the main buttress and the receiving buttress in a position to absorb the energy of a vehicle collision. The drive mechanism is electro-mechanical or hydraulic. The final drive is via rack and pinion with V-groove wheels in sub-grade or at-grade ground tracks.  The gate can be tailored to match the surrounding decor in a wide variety of architectural treatments. Standard sizes are 108 inches (2.74 m) high and 144 inches (3.65 m) long. Clear openings of up to 33 feet (10 m) may be specified. A non-crash-rated form—the SC3000—is also available. TT300: High-security rolling pedestrian gate The TT300 high security, rolling gate is ideal for installations that need a heavy-duty non-crash- rated gate but still demand rugged performance. The drive mechanism is electro-mechanical or hydraulic. TT300 high security, the rolling gate is ideal for installations that need a heavy-duty non-crash- rated gate  The final drive is via rack and pinion with V-groove wheels in sub-grade or at-grade ground tracks. The standard design is 9 feet (2.7 m) tall and is specifically designed for openings over 33 feet (10 m). The gate can be tailored to match the surrounding decor in a wide variety of architectural treatments. SGC1000: Manual crash-rated swing gate The SGC1000 fills the need for a rugged manual crash-rated swing gate. The design of the end support assemblies adds to its crash-rated performance. A ground track is not needed. The SGC1000 provides a clear opening of 12 to 30 feet (3,657 mm to 9,144 mm). The gate can be tailored to match the surrounding decor in a wide variety of architectural treatments. DSC288: High-security sliding gate  For the first time, a high security (DOS K12/ASTM M50– no penetration) gate can now fully match the perimeter fence in materials ranging from wood, steel, mesh, glass, fence pickets, or railings. Anti-climb, clear, or opaque ballistic infill are all available. The gate is guided from the rear side leaving out the front buttresses. This provides the architect and security engineer flexibility on the face treatment or infill of the gate. The gate can be supplied as an open frame for field fitting or supplied completely assembled. The crash beam behind the gate stops the vehicle, not the face. DSC288 Features The DSC288 features a shallow foundation of only 33.5 inches (85 cm) to avoid underground utility conflicts. It also significantly lowers the time and cost of implementation. A typical implementation can be completed in only three days. DSC288 features plug-and-play touch screen control panels with intelligent monitoring and programmable logic control For easy operation, it features plug-and-play touch screen control panels with intelligent monitoring and programmable logic control. A positive latch pin secures the gate in the fully closed position and protects against mobs forcing the gate open. Clear openings range from 120 inches (3m) to 360 inches (9.1 m). There are four versions: DSC288 Full Size Slide Gate DSC286 Low Profile Slide Gate DSC284 Sliding Beam Gate DSC290 Cantilever Gate Custom heights and widths are available A Variety of Power Options Depending on the gate, Delta gates can be powered manually, electro-mechanically, or hydraulically.
