Purpose Provides basic information for emergency personnel responding to a fire or spill and those planning for emergency response. Informs workers about the hazards of chemicals in workplace under normal conditions of use and foreseeable emergencies.
Number System: NFPA Rating and OSHA's Classification System 0-4
0-least hazardous
4-most hazardous
1-most severe hazard
4-least severe hazard
-The Hazard category numbers are NOT required to be on labels but are required on SDSs in Section 2.
-Numbers are used to CLASSIFY hazards to determine what label information is required.
Information Provided on Label
  • Health-Blue
  • Flammability-Red
  • Instability-Yellow
  • Special Hazards*-White
*OX Oxidizers
W Water Reactives
SA Simple Asphyxiants
  • Product Identifier
  • Signal Word
  • Hazard Statement(s)
  • Pictogram(s)
  • Precautionary statement(s); and

Acute (short term) and chronic (long term) health hazards. Both acute and chronic health effects are relevant for employees working with chemicals day after day. Health hazards include acute hazards such as eye irritants, simple asphyxiants and skin corroxives as well as chronic hazards such as carcinogens.
Flammability/ Physical Hazards on Label NFPA divides flammability and instability hazard into two separate numbers on the label.
Flammability in red section
Instability in yellow section
A broad range of physical hazard classes are listed on the label including explosives, flammables, oxidizers, reactives, pyrophorics, combustible dusts and corrosives.
Where to get information to place on label Rating system found in NFPA Fire Protection Guide to Hazardous Materials OR NFPA 704 Standard System for Identification of the Hazards of Materials for Emergency Response 2012 Edition. Tables 5.2, 6.2, 7.2 and Chapter 8 of NFPA 704 OSHA Hazard Communication Standard 29 CFR 1910.1200 (2012).
  1. Classify using Appendix A (Health Hazards) and Appendix B (Physical Hazards)
  2. Label using Appendix C
