A Bremer wall, or T-wall, is a twelve-foot-tall (3.66 m) portable, steel-reinforced concrete blast wall of the type used for blast protection throughout Iraq and Afghanistan. The Bremer barrier resembles the smaller 3-foot-tall (0.91 m) Jersey barrier, which has been used widely for vehicle traffic control on coalition military bases in Iraq ...
A blast pen and memorial at the former RAF Kenley A Hawker Hurricane in a revetment at RAF Wittering in 1940. A blast pen was a specially constructed E-shaped double bay at British Royal Air Force (RAF) Second World War fighter stations, being either 150 ft (46 m) or 190 ft (58 m) wide and 80 ft (24 m) front-to-back, accommodating aircraft for safe-keeping against bomb blasts and shrapnel ...
U.S. and Afghan soldiers standing behind a blast wall made from HESCO bastions in Afghanistan in 2012. A blast wall is a barrier designed to protect vulnerable buildings or other structures and the people inside them from the effects of a nearby explosion, whether caused by industrial accident, military action, or terrorism.
Explosion protection is used to protect all sorts of buildings and civil engineering infrastructure against internal and external explosions or deflagrations. It was widely believed [ 1 ] until recently that a building subject to an explosive attack had a chance to remain standing only if it possessed some extraordinary resistive capacity.

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 ...
The primary North American document that deals with outdoor high-voltage transformer fire barriers is NFPA 850. [1] NFPA 850 outlines that outdoor oil-insulated transformers should be separated from adjacent structures and from each other by firewalls, spatial separation, or other approved means for the purpose of limiting the damage and potential spread of fire from a transformer failure.
Blast shelters are a vital form of protection from nuclear attacks and are employed in civil defense. There are above-ground, below-ground, dedicated, dual-purpose, and potential blast shelters. Dedicated blast shelters are built specifically for the purpose of blast protection (see bunker). Dual-purpose blast shelters are existing structures ...
