UNUSUAL FIRE AND EXPLOSION HAZARDS: Ignites and is potentially
explosive in atmospheres of carbon dioxide. Chromium reacts violently
or explosively when heated with ammonium nitrate and bromine
pentafluorde. Chromium has an incandescent reaction with nitrogen oxide
or sulfur dioxide. Powders prepared by evaporation of mercury from
chromium amalgam may be pyrophoric.
