The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or protection.
A blast wave phenomenon is an incident involving the violent release of energy created by detonation of an explosive device.
This pressure increase or “shock front,” travels radially outward from the detonation point, with a diminishing velocity that is always in excess of the speed of sound in that medium.
These fragments usually are small, initially travel at thousands of feet per second, and may be lethal at long distances from an explosion.
All explosives compound molecules are potentially unstable held together with weak bonds in their outer shell.
This does not imply that there is a time lapse between blast and fragmentation effects of explosives; in fact it happens so fast that humans cannot notice the delay without specialized equipment.
The primary concern for explosives safety with a fire involving A&E is that it may transition to a more severe reaction, causing detonations of additional or more hazardous explosives devises and placing more people or property at a greater degree of risk of damage, destruction, injury, or death.
The finding triggered research by scientists in the United States into safer conventional explosives that could be used in nuclear weapons.
The test projectile is fired under controlled conditions at a hard surface to measure the reactions and thresholds of different explosives to an impact.
They are responsible to recommend to military command ways to store A&E that reduce the risk of injury or death to service men and women in case of an accidental detonation or if the A&E supply is hit by enemy attack.
This management process also ensures that risks above those normally accepted for A&E activities are identified and approved at the proper level of command.
They must also work with ammunition cleanup sites insuring that safety laws and regulations as well as industry standards are followed.
