When sodium azide enters in contact with an acid, it produces volatile [[hydrazoic acid]] ({{Chem2|HN3}}), as toxic and volatile as [[hydrogen cyanide]] (HCN).

[[Heavy metals|Heavy metal]] azides, such as [[lead azide]] ({{chem2|Pb(N3)2}}) are [[primary explosives|primary]] [[high explosive]]s [[detonation|detonable]] when heated or shaken. Heavy-metal azides are formed when solutions of sodium azide or {{chem2|HN3}} vapors come into contact with heavy metals (Pb, Hg…) or their salts. Heavy-metal azides can accumulate under certain circumstances, for example, in metal pipelines and on the metal components of diverse equipment ([[rotary evaporator]]s, [[freeze drying|freezedrying]] equipment, cooling traps, water baths, waste pipes), and thus lead to violent explosions.<ref name="Rozycki1981" />
