Delta Scientific prevents two vehicle attacks

August 2019 Editor's Choice, Access Control & Identity Management, Security Services & Risk Management

Delta Scientific recently announced that, on June 3, 2019, when a man couldn’t produce credentials at Mayport Naval Station, he gunned his engine and attempted to enter. The security staff activated their vehicle access barrier, a Delta DSC501, to rise out of the ground. The vehicle crashed into it and was brought to a standstill. The violator was taken to the hospital and died two days later.

Eight days later, on June 11, a man, driving a Ford F-350 truck, also tried to get on base. Again, the DSC501 popped out of the ground and the attacker collided with it and the truck was stopped in its tracks. The violator was arrested and is now facing charges.

“This high security barricade was originally designed for the US Navy and has also been selected for use at US Embassies, among many others. Set in a foundation only 18 inches deep, the Delta DSC501 is able to survive and operate after a 1.2 million foot/pound impact,” attests Greg Hamm, Delta Scientific vice president, sales and marketing. “In testing, the DSC501 not only stopped and destroyed a 65 000-pound (5.4 million foot/pounds) dump truck but the barricade continued to stand, preventing a potential second attack.”

In the United Kingdom, the DSC501 high security barricade has also been tested to stop a 7500 kg vehicle travelling 80 kmph, meeting the BSI standard PAS:68 2007. During this test, zero penetration occurred and the system was fully functional after the vehicle was removed – ready to face a second attack.

In the lowered position, the DSC501’s barrier ramp is completely flush with the roadway. Buttresses, counterweights and road plates do not obstruct authorised pedestrian or vehicular traffic. The DSC501 is raised and lowered to and from the guard position via hydraulic cylinders driven by Delta’s patent-pending hydraulic power unit. This unit can be configured to operate one or more DSC501’s and provide pass-through rates of 3 to 15 seconds, suitable for most inspection and identification station requirements. However, when danger is imminent, the barricade rises in less than 2 seconds.

The DSC501 is suitable for high water table locations and areas with corrosive soils. 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.

Its K12/L3 certification meets the government’s highest levels. With its shallow foundation and aesthetic design, this anti-terrorist barricade 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 DSC501 is suitable for high water table locations and areas with corrosive soils.
