Crash-rated barriers have long history with U.S. Department of State

Crash-rated barriers have long history with U.S. Department of StateVisit any U.S. Embassy throughout the world, including major embassies, such as Beijing, and smaller ones in Estonia, Indonesia, Papua New Guinea, Ivory Coast, Guatemala, Nepal, Lithuania and Madagascar, even consulates in Florence, Italy, Sarajevo, Vienna and cities in Germany, Greece, Macedonia and Saudi Arabia, and you will find them protected from vehicle assaults and some even from bio-attacks.

The following provides examples in which highly-secure, crashrated, vehicle barricade systems and bollards have saved lives as well as buildings and property from the destruction of attacks.

U.S. Embassy in Dar Es Salaam, Tanzania and Nairobi, Kenya. In Tanzania, 1998, a crash-rated, moveable barricade prevented an attacker’s vehicle from entering the rear compound of the building, thus, reducing the loss of lives and damage to the facility. Unfortunately, no barricades were used at the embassy in Kenya when it was bombed the same day.

By September of that year, however, 14 barriers, including moving- wedge barricades and crash-rated bollards, were shipped to these two embassies.

Harry S. Truman Building. At the dedication of the U.S. Department of State headquarters, held in Washington, D.C. on Sept. 22, 2000, bollards provided a first line of defense by securing the diplomatic and congressional drive entrances.

These custom, stainless-steel bollards feature lights to improve visibility at night. They are designed to destroy the front suspension system, steering linkage, engine crank case and portions of the drive train of any 15,000-pound, non-armored or non-tracked vehicle hitting them at 62 mph. The system will also stop a 30,000-pound vehicle traveling at 44 mph.

These bollards are raised and lowered into the guard position by a remote controlled, precision, hydraulic power unit or a precision pneumatic power system. Under emergency conditions, the bollards can be raised in as little as a single second. And, with the exception of minor, non-structural damage, such as scratches, they are fully operational after taking a 65 mph hit from a five-ton vehicle.

Yemeni port of Aden. Just one month after the dedication of the U.S. Department of State headquarters and within hours after the terrorist bombing of the USS Cole at the Port of Aden, on Oct. 12, 2000, barriers were airlifted to Yemen for deployment there and at nearby, prospective targets.

U.S. Embassy in Yemen. At the most recent attack in September 2008, barricades were up protecting the entrance and keeping bombers outside the compound. These barriers tested at K54, which will stop a 65,000-pound truck, traveling at 70 mph. That’s 5.4 million foot-pounds of energy!

At the entrance to the embassy, the barrier creates a sally-port with a crash-resistant gate to tightly control traffic into the embassy. It is lowered to let in a car, while the gate in front of the car stays closed. The barrier in back then raises, and the car is sandwiched between it and the gate. Once searched and approved, the gate opens, and the car is allowed to enter the embassy.

U.S. Embassy in Amman, Jordan. Situated in the middle of one of the most volatile areas of the world, this embassy relies on a crashrated barrier to protect its facilities from the threat of terrorism. The barrier protects the compound from charging vehicles and creates a sally-port, similar to that at the Yemeni embassy, which tightly controls traffic into the embassy.

U.S. Consulate in Peshawar, Pakistan. In 2010, barricades helped retain attackers by preventing a bomber’s vehicle from crashing past pedestrian gates, forcing the attackers to detonate a truck bomb far from the building. The barricades successfully stopped the attack vehicle away from the building and diminished the high-pressure shock wave of a bomb blast, saving lives and the property.

With more than 170 U.S. Embassies and Consulates in 130-plus countries, it is imperative to incorporate premier, perimeter protection that meets or exceeds U.S. Department of State and Department of Defense certification standards, while providing high-security in order to counter terrorism.

    I’m a recovering alcoholic, ten years sober this June. I almost wrote “recovered alcoholic,” because it’s a problem I’ve long since put to bed in every practical sense. But anyone who’s dealt with addiction knows that that part of your brain never goes away. You just learn to tell the difference between that insidious voice in your head and your actual internal monologue, and you get better at telling the other guy to shut up. Read Now

    My first security trade show was in 2021. At the time, I was awed by the sheer magnitude of the event and the spectacle of products on display. But this was the first major trade show coming out of the pandemic, and the only commentary I heard was how low the attendance was. Two representatives from one booth even spent the last morning playing catch in the aisle with their giveaway stress balls. Read Now
