Physical Hazards of Chemicals
The physical hazards of a chemical include its flammability and reactivity. Flammability is the tendency of a chemical to burn. The flashpoint, auto ignition temperature and flammable limits of the material may be found in the Safety Data Sheet (SDS), and are helpful in assessing the potential for a fire hazard under specified conditions.
Reactivity is the potential of the material to explode or react violently with air, water or other substances upon contact. The SDS furnishes this information in the Stability and Reactivity Data section.
