Do the shipping papers have:
• An entry with a proper shipping name, hazard class, and ID number?
• A highlighted entry or one with an X or RQ in the hazardous materials column?
If so, these are indications that the shipment includes hazardous materials.
Other clues suggesting hazardous materials include:
• What business the shipper is in (e.g., paint dealer, chemical supply, scientific supply house, pest control or agricultural supplier, explosives, munitions or fireworks dealer)
• Tanks with diamond labels or placards on the premises
• Type of package being shipped. Cylinders and drums often are used for hazardous materials shipments
• Hazard class label, proper shipping name, or ID number on a package
• Handling precautions noted
