Regulatory requirements from the US Department of Transportation covering the safe transport of hazardous materials by road, rail, air, and water.
DOT compliance under 49 CFR covers hazardous materials transportation (HMR — Parts 171-180), including classification, packaging, marking, labelling, placarding, shipping papers, and emergency response information. Shippers must classify hazardous materials into one of nine hazard classes, select proper packaging, provide 24/7 emergency response contact, and train all hazmat employees within 90 days. DOT drug and alcohol testing (Part 40) applies to safety-sensitive transportation employees and includes pre-employment, random, post-accident, and reasonable suspicion testing.
