SAFETY PROFILE：
Severe explosion hazard when shocked or exposed to heat. Acetylides are very sensitive to shock, friction, and heat. They explode readily and are among the few commercial explosives that contain no oxygen or nitrogen and therefore produce no gas. The explosion simply results from the large amount of heat instantaneously produced. Acetylides are used for detonating compositions, or in combination with lead azide in detonating rivets, where the acetylides reduce the flash point of the more insensitive azides. They are in a class with the fulminates and the azides as primary detonants. Because these materials are so sensitive to shock and temperature, they must be handled with extreme care. They must be kept cool, and should be kept wet if they are to be stored. (See FULMINATES for suggested precautions in storage and handling of acetylides.) Metal powders, such as finely divided Cu or Ag, should not be stored or kept with acetylene or acetylides because it is possible for these substances to react with these metal powders to form very sensitive acetylides, although they are not dangerous in themselves, can cause enough of a flash to ignite a possibly explosive mixture of gases and thus cause an explosion in a warehouse or storage area. Examples of commercially used acetylides are silver acetylide and copper acetylide. See also ACETYLENE. See also individual compounds.
