Hazard Communication Program

Each HSC component must have a written Hazard Communication Program that complies with OSHA standards and the Texas Hazard Communication Act for hazardous chemicals. This program is available from your components safety officer. It requires the following:

  • Employee training (including recognition of signs of exposure)
  • Labeling procedures
  • MSDSs for chemicals at each workplace
  • Instructions on how to read and interpret MSDSs
  • Chemical inventory reporting procedures
  • Recordkeeping requirements
  • Emergency response procedures

Refer to your components Hazard Communication Program for detailed information on these topics.

An integral part of hazard communication is hazard identification. Everyone who works with hazardous chemicals should know how to read and interpret hazard information. Signs, like the NFPA diamond in the illustration below, alert employees to the known hazards in a particular location.

Hazard codes

The following is a detailed explanation of the NFPA hazard classification codes:

Health (Blue):

4 - Can cause death or major injury despite medical treatment (Deadly)

3 - Can cause serious injury despite medical treatment (Extremely Hazardous)

2 - Can cause injury. Requires prompt medical treatment (Moderately Hazardous)

1 - Can cause irritation if not treated (Slight Hazardous)

0 - No hazard

Flammability (Red)

4 - Very flammable gases or liquids

(Flash point below 73o F)
3 - Can ignite at normal temperatures

(Flash point below 100o F)

2 - Ignites with moderate heat (Flash

point between 100 - 200o F)

1 - Ignites with considerable

preheating (Flash point above 200o F)

0 - Will not burn

Reactivity (Yellow)

4 - Readily detonates or explodes

3 - May detonate or explode with strong initiating force or heat under confinement

2 - Normally unstable, but will not detonate

1 - Normally stable. Unstable at high temperature and pressure.

0 - Normally stable and not reactive with water.

Specific Hazard (White)

Oxidizer - OX

Acid - ACID

Alkali - ALK

Corrosive - COR

Use No Water ? W

Radioactive - radioactive symbol
