Hazardous materials pose a threat to the public. Millions of packages and shipments containing hazardous materials are transported daily. Placards affixed to each load alert handlers of the hazards associated with the contents. When accidents occur, placards identify the material so an appropriate response can be undertaken. The U.S. Department of Transportation regulates the handling and shipping of hazardous materials under Title 49 of the United States Code of Federal Regulations (49CFR), which is also known as the Federal Motor Carriers Safety Regulations (FMCSR). - Hazmat regulations require that non-bulk 119-gallon packages be marked with the material's proper shipping name (PSN), United Nations/North American (UN/NA) identification number, and the name and address of the consignor or consignee. Additional markings may be required depending on the material and shipment.

However, during transport, containers must also display the appropriate DOT markings and labels. Typical hazardous waste labels combine the required DOT and waste markings and provides space for the user to enter additional mandatory and voluntary information. - Placards are 273 mm x 273 mminhalation hazard class 2 image by k9dg from Fotolia.com
