WHAT IS IN THE HAZARDOUS INGREDIENTS SECTION ON AN MSDS?
A chemical is not normally simply one chemical, but composed of several chemicals in a mixture. If the chemical is not a mixture, this section will list the hazardous chemical material and its health/physical hazards and permissible exposure limits. If the chemical is a mixture, the common name of the mixture and its hazardous ingredients will be listed along with the know health/physical hazards and exposure limits. It’s important to know and understand the chemical ingredients of any mixture, as a mixture may pose more than one health or physical hazard. The chemical manufacturer will explain the precautions and other information when using a mixture of any chemical. Carcinogens (capable of causing cancer) must be listed if they make up more than one-tenth of one percent of the total mixture. Any ingredients posing a physical hazard, such as harmful to skin or other physical hazards must also be listed.
