13. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS "The ability of a material to cause injury to a person through contact or entry to the body via inhalation, ingestion, skin contact or eye contact"

14. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS Heat from a fire. Force from an explosion. Health hazards resulting from long-term exposure, either chronic or repeated to low concentrations of hazardous materials.

15. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS Materials that, under emergency conditions, can be lethal. 4

16. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS Materials that, under emergency conditions, can cause serious or permanent injury. 3

17. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS Materials that, under emergency conditions, can cause temporary incapacitation or residual injury. 2

18. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS Materials that, under emergency conditions, can cause significant irritation. 1

19. NFPA 704 – Hazard Identification SystemHEALTH HAZARDS Materials that, under emergency conditions, would offer no hazard beyond that of ordinary combustible materials. 0

20. NFPA 704 – Hazard Identification SystemFLAMMABILITY HAZARDS The ability of a material to burn under one set of conditions, but not under others. The form or condition of the material. The inherent properties of the material.

21. NFPA 704 – Hazard Identification SystemFLAMMABILITY HAZARDS Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature or that are readily dispersed in air and will burn readily. 4

22. NFPA 704 – Hazard Identification SystemFLAMMABILITY HAZARDS Liquids and solids that can be ignited under almost all ambient temperature conditions. Materials in this degree produce hazardous atmospheres with air under almost all ambient temperatures or, though unaffected by ambient temperatures, are readily ignited under most all conditions. 3

23. NFPA 704 – Hazard Identification SystemFLAMMABILITY HAZARDS Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials in this degree would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air. 2

24. NFPA 704 – Hazard Identification SystemFLAMMABILITY HAZARDS Materials that must be preheated before ignition can occur. Materials in this degree require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. 1

25. NFPA 704 – Hazard Identification SystemFLAMMABILITY HAZARDS Materials that will not burn under typical fire conditions, including intrinsically noncombustible materials such as concrete, stone and sand. 0

26. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS "degree of intrinsic susceptibility of materials to release energy"

27. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS “capable of rapidly releasing energy by themselves either through self-reaction or polymerization"

28. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS Whether an area should be evacuated. If a protected location should be used while fighting a fire. Whether caution should be used when approaching a spill or fire. If the application of extinguishing agents is appropriate. Or whether a fire can be fought using normal procedures

29. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS Materials that in themselves are readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures pr pressures. 4

30. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS Materials that in themselves are capable of detonation or explosive decomposition or explosive reaction, but that require a strong initiating source or that must be heated under confinement before initiation. 3

31. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS Materials that readily undergo violent chemical change at elevated temperatures and pressures. 2

32. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS Materials that in themselves are normally stable, but that can become unstable at elevated temperatures and pressures. 1

33. NFPA 704 – Hazard Identification SystemINSTABILITY HAZARDS Materials that in themselves are normally stable, even under fire conditions. 0

34. NFPA 704 – Hazard Identification SystemSPECIAL HAZARDS “cause special problems or require special fire-fighting techniques."
