MSDSMaterial Safety Data Sheet

of a chemical product. They are designed for:
workers who may be exposed to hazardous materials
emergency personnel (for example, firefighters),who may have to clean up a spill or release.

Blue: health hazard Red: flammability Yellow: (chemical) reactivity White: special codes for unique hazards.
Each is rated on a scale: from 0 (no hazard; normal substance) to 4 (severe
risk).
