Quantity-distance (QD) is the foundation of DOD explosives safety standards. It defines levels of protection from blast based on relationships between the quantity of explosive material (NEW) and distance. The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or ...
A briefcase or suitcase bomb with about 50 pounds (22.67 kg) of explosives has a 150-foot (46 m) standoff distance. [3] Larger car bombs or truck bombs have a much larger standoff distance, as the blast radius is bigger. [3] A car bomb with a 500-pound (226.79 kg) bomb has a 320-foot (97.5 m) standoff distance.

Because there are different ways to set off explosives, there are several different components to the safety testing of explosives: Impact testing: The impact testing of explosives is performed by dropping a fixed weight onto a prepared sample of the explosive to be tested from a given distance.
Mont-Blanc, laden with high explosives, caught fire and exploded, devastating the Richmond district of Halifax. At least 1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time. [1]
Series 5 tests are used to determine if an article can be assigned to HD1.5 'Very Insensitive Explosive'; series 6 tests are used to determine the classification of an article within Hazard Divisions 1.1, 1.2, 1.3, or 1.4; and series 7 tests are used to determine if an article can be assigned to HD 1.6 as an article containing predominantly ...
The net explosive quantity (NEQ), also known as net explosive content (NEC) or net explosive weight (NEW), of a shipment of munitions, fireworks or similar products is the total mass of the contained explosive substances, without the packaging, casings, bullets etc. [1] It also includes the mass of the TNT-equivalent of all contained energetic substances.

A blast radius is the distance from the source that will be affected when an explosion occurs. A blast radius is often associated with bombs , mines , explosive projectiles ( propelled grenades ), and other weapons with an explosive charge.
