or who are expected to recognize such hazards
- personnel are expected to protect themselves, call for trained personnel and
protect the area

- Analyze the incident to detect hazardous materials
- ID the chemical name, UN#, placard or other markings

3 - can cause serious or permanent injury
4 - can be lethal
Rating numbers for flammability hazard (red part of diamond)
0 - will not burn
1 - must be preheated before ignition can occur
2 - must be heated or high ambient temperature to burn
3 - can be ignited under almost all ambient temperatures
4 - will vaporize and readily burn at normal temperatures
Rating numbers for instability hazard (yellow part of diamond)
0 - stable
1 - normal stable. High temperatures make unstable
