Explosives classes

Low Level Waste. The NRC 10CFR61 specifies the nature of the protection required for waste containers (20). Class A wastes must meet minimum standards, including no use of cardboard, wastes must be solidified, have less than 1% Hquid, and not be combustible, corrosive, or explosive. Class B wastes must meet the minimum standards but also have stabiHty, ie, these must retain size and shape under soil weight, and not be influenced by moisture or radiation. Class C wastes must be isolated from a potential inadvertent intmder, ie, one who uses unrestricted land for a home or farm. Institutional control of a disposal faciHty for 100 years after closure is requited. 

Dust explosions class, St Dusts are classified in accordance with the Kmax values. 

Explosion. Use shielding when working with explosive classes such as acetylides, azides, ozonides, and peroxides. Peroxidizable substances such as ethers and alkenes, when stored for a long time, should be tested for peroxides before use. Only sparkless flammable storage refrigerators should be used in laboratories.

The most sensitive of the military explosives classed as primary explosives. In a finely divided state, it is as sensitive as mercury fulminate. Veiy sensitive to heat, shock, and friction. Sharp blows or metal-on-metal friction is sufficient to cause detonation. Readily detonated by bullet impact and may be ignited by sparks. Not normally ignited or detonated by static electricity generated on the body or in routine handling. Extremely sensitive to ignition by lead azide but not from the spit of a fuze. Very insensitive to flame, shock, and friction in primacord so must be detonated by cap. Does not detonate under long, slow pressure.
