Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
A blast valve is placed in air intake/exhaust pipes, that remains open normally, but automatically closes when strong pressure is applied in either direction. Blast dampers operate in the same fashion and are related or identical to blast valves, the former name however is generally used to describe blast mitigation devices, for more ...
The technology of protection [4] can range in price dramatically but where the type of device is rational to use, is typically from the least to the most expensive solution: explosion doors and vents (dependent on quantities and common denominators); inerting: explosion suppression; isolation – or combinations of same.
The PMN-2 mine casing is made from injection-molded plastic. In general, the color is leaf-green, but occasionally brown examples may be encountered. The top of the mine has a black rubber X-shaped pressure plate. The filling is an RDX/TNT based explosive that is quite similar to Composition B. As with the PMN-1, the PMN-2 has an unusually ...
X-Series PB-7910T Gas-Engine Backpack Leaf Blower. Echo’s yard machines rarely lack for power, but the PB-7910T backpack gas engine leaf managed to exceed expectations, maxing out with an air ...
The Advanced Bomb Suit (ABS) is a full body bomb suit designed to protect explosive ordnance disposal (EOD) soldiers from threats associated with improvised explosive devices, including those related to fragmentation, blast overpressure, impact, heat, and flame. Manufactured by Med-Eng, the ABS uses new material technology and design to improve ...
An explosion vent or rupture panel [1] [2] is a safety device to protect equipment or buildings against excessive internal, explosion-incurred pressures, by means of pressure relief. An explosion vent will relieve pressure from the instant its opening (or activation) pressure p stat has been exceeded.
Parts of the bomb suit overlap for maximum protection. The suit protects in several different ways. It deflects or stops projectiles that may come from an exploded device. It also stops or greatly decreases the pressure of the blast wave being transmitted to the person inside of the suit.
