ELA 963 Fire Hazards Practice Test

The way the US DOT labels flammable liquids is about transporting hazards, not about on-site safety ratings. DOT uses its own Hazardous Materials Regulations with clear shipping requirements: hazard class, UN number, proper shipping name, packing group, and specific labels or placards for transport. That system is distinct from NFPA 704’s on-site hazard diamond and from OSHA’s HazCom/GHS workplace labeling. So for DOT hazmat labeling, it does not follow NFPA or OSHA; it follows its own transport-focused system.
