What is Hazard Communication?
• Hazards and dangers should be made known to all personnel involved.
• Right-to-know Law by OSHA• Use of symbols, warnings and written
documentation to alert personnel.• NFPA Diamond, Pictograms, MSDS

Material Safety Data Sheets (MSDS)are one of the most important tools
available to employers for providing information, and protectionto workers from hazardous chemicals
which are used in the workplace.
