• Description:
  Explosions due to azides used during analysis techniques are discussed. The ability of dilute sodium-azide (26628228) solutions to form explosive heavy metal azide salts after prolonged exposure to metals such as lead (7439921) or copper (7440508) is examined. Three specific instances of explosions caused by azides are related. The first concerns an explosion caused by the use of sodium-azide to prevent the growth of organisms in a water bath containing copper. The second deals with sodium-azide reacting with a brass plug in a water bath. The third incident involves plumbing fixtures that received the waste of blood cell counters where azides were used as diluents. Measures to prevent azide related explosions are outlined. Methods of decontaminating plumbing systems containing lead-azide are discussed. The advantages of using sodium-hydroxide (1310732) for this purpose are cited. Problems in decontaminating plumbing systems are outlined. An explosion occurring in a decontaminated plumbing system is described. [Description provided by NIOSH]
