Most Interesting Chemical: Sodium Nitrite - A
yellowish white crystalline solid. Noncombustible but will accelerate the
burning of combustible material. If large quantities are involved in a fire or
if the combustible material is finely divided, an explosion may result. If
contaminated by ammonium compounds, spontaneous decomposition can occur and the
resulting heat may ignite surrounding combustible material. Prolonged exposure
heat may result in an explosion. Toxic oxides of nitrogen are produced in fires
involving this material. Used as a food preservative, and to make other
chemicals. (Source: CameoChemicals.NOAA.gov).
