Final answer:
The hazard class, division, and compatibility of a material can be determined using the NFPA 704 Hazard Identification System, which uses a diamond symbol with different colored sections to represent different hazards.
Step-by-step explanation:
The hazard class, division, and compatibility of a material can be determined by using the National Fire Protection Agency (NFPA) 704 Hazard Identification System. This system uses a diamond symbol with different colored sections to represent different hazards. The red section indicates the fire hazard, the blue section indicates the health hazard, the yellow section indicates the reactivity hazard, and the white section indicates special hazards. Each hazard is rated on a scale from 0 to 4.
