The HMIS rating is a color-coded, alphanumeric system which gives information about the health, flammability and reactivity of the chemical in question. The system rates a material from a minimal hazard through a serious hazard. It also recommends the appropriate personal protective equipment to be worn when handling the particular chemical.
