r <br />Hazard Communication & Safety Data Sheets <br />Large Chemical Containers and Buildings — For chemicals stored in large quantity containers, or for <br />buildings that house large amounts of chemicals a different system of identification is used, it may be placed <br />on the container or on the outside of the building, or both. This is known as the "NFPA" system, (National Fire <br />Protection Association). <br />The NFPA Diamond sign is used to warn firefighters and emergency responders of the hazards they may be <br />exposed to in the event of a chemical fire, spill or release to atmosphere. <br />Note that the NFPA diamond has no designation for PPE, nor does it carry an <br />area for the chemical name, however the colors and numbers are the same as <br />the HMIS system. <br />Instability Hazard <br />0 = Normally stable even under fire con- <br />ditions. <br />1 = Normally stable materials that can <br />become unstable at elevated temperatures <br />and pressures. <br />2 = Materials that readily undergo violent <br />chemical change at elevated temperatures <br />and pressures. <br />3 = Materials capable of detonation, or <br />explosive decomposition, or explosive <br />reaction, but that require a strong initiating <br />source, or that must be heated under con- <br />finement before initiation. <br />4 = Materials readily capable of detonation <br />or explosive decomposition or explosive <br />reaction at normal temperatures and pres- <br />sures. <br />Other Hazards <br />W = water reactive <br />OX = oxidizer <br />COR = corrosive <br />ACID = acidic <br />ALK = alkaline or caustic <br />® = radioactive <br />These are examples: other symbols may <br />be present. <br />Both HMIS and NFPA systems are designed to give you information on chemical hazards, they can be seen <br />in various locations at Unified facilities. If you need to label a container, ask your supervisor for the HMIS <br />label(s), all the information you need to correctly fill out the label can be found in the Safety Data Sheet for <br />that chemical. Remember: <br />• READ the Safety Data Sheets before using the chemicals <br />• NEVER use smell or taste as a means to identify a chemical El, y"F <br />• ALWAYS wear your PPE — Level B Minimum <br />• EVERY chemical container must carry a legible label SEP 19 2014 <br />• NEVER mix chemicals without proper knowledge or instruction <br />• REPORT spills or leaks immediately ENVIRONMENTAL HEALTH <br />DEPARTMENT <br />3 <br />
