Hazardous Materials Regulations, Definitions, and Communication Rules
The regulations domain tests the rulebook behind every other hazmat decision: which materials are regulated, who must be trained, and how the four communication requirements fit together. New Jersey CDL questions draw on 49 CFR Parts 171–180, which New Jersey adopts for intrastate and interstate operations.
Core rules
- A hazardous material is a substance or material capable of posing an unreasonable risk to health, safety, or property when transported, and that is listed or meets a hazard class definition in Part 173.
- A hazmat employee is anyone who affects hazmat transportation safety: loading, unloading, handling, inspecting, marking, labeling, placarding, preparing shipping papers, or operating the vehicle. Training is required within 90 days of hire and recurrent training at least every 3 years, with records kept.
- Bulk packaging means a maximum capacity greater than 119 gallons for a liquid, greater than 882 pounds for a solid, or greater than 1,000 pounds water capacity for a gas. Non-bulk is at or below those limits.
- The four communication requirements are shipping papers, package marking, package labeling, and vehicle placarding. They work together; a missing one is a violation even if the others are correct.
Worked example
A driver is offered a 150-gallon portable tank filled with gasoline. Because 150 gallons exceeds the 119-gallon liquid bulk threshold, the tank is a bulk packaging. Gasoline is a Class 3 flammable liquid, so the shipment needs a shipping paper with the basic description, a placard on the vehicle, and the tank marked and labeled as required. A 100-gallon drum of the same gasoline would be non-bulk.
Traps that cost marks
Exactly 119 gallons is not bulk. Training is every 3 years, not annually. A driver who only drives the loaded vehicle is still a hazmat employee. "Hazardous substance" is a narrower term than "hazardous material" and depends on the reportable quantity in one package.
