keep PART 172—HAZARDOUS MATERIALS TABLE, SPECIAL PROVISIONS, HAZARDOUS MATERIALS COMMUNICATIONS, EMERGENCY RESPONSE INFORMATION, TRAINING REQUIREMENTS, AND SECURITY PLANS
The regulation establishes the Hazardous Materials Table (49 CFR § 172.101), which classifies and lists hazardous materials for transportation, setting requirements for shipping papers, packaging, labeling, placarding, quantity limits, and vessel stowage to ensure safe transport by air, highway, rail, or water.
Americans would be worse off due to heightened risks of catastrophic accidents, environmental damage, and uninformed emergency response. The regulation prevents clear negative externalities in a cost-effective manner; uniform federal standards are necessary for interstate commerce and provide critical safety information that private ordering or state-by-state rules cannot reliably deliver.
