Due to their [[Volatility (chemistry)|volatility]], they are more toxic in confined areas than in open areas.<ref name="Walsh 150" />

[[Cyanide]] compounds occur in small amounts in the natural environment and in [[cigarette smoke]]. They are also used in several industrial processes and as pesticides. Cyanides are released when [[synthetic fabric]]s or [[polyurethane]] burn, and may thus contribute to fire-related deaths.<ref name="Walsh 151">Walsh, 151.</ref> [[Arsine]] gas, formed when [[arsenic]] encounters an acid, is used as a pesticide and in the semiconductor industry; most exposures to it occur accidentally in the workplace.<ref name="Walsh 151" />
