Labeling Hazardous Waste

All hazardous waste needs to be properly labeled.

There are certain requirements set by both the DOT and the EPA for the marking of hazardous waste containers before and during shipment.

Generators of hazardous waste may keep hazardous waste on site as long as they follow the rules in 40 CFR part 262, subpart C (1). Depending on each individual’s generator status, hazardous waste may need to be marked with “Hazardous Waste” along with other signifying information such as the accumulation start date.

EPA regulation regarding the labeling of  non-bulk packaging of hazardous material must include the following verbiage:

HAZARDOUS WASTE-Federal Law Prohibits Improper Disposal. If found, contact the nearest police or public safety authority or the U.S. Environmental Protection Agency.
Generator’s Name and Address _____________.
Generator’s EPA Identification Number __________________.
Manifest Tracking Number ___________________.

The DOT standard for hazardous waste begins before shipment of waste to an offsite location, regardless of whether the shipment is for treatment, disposal or storage.

For shipments of hazardous material, including hazardous wastes, the DOT requires each non-bulk package (maximum capacity no more than 119 gallons) to display, at a minimum:

  • The Proper Shipping Name and identification number of the hazardous material [49 CFR 172.301(a)];
  • The name and address of the shipper and/or the designated recipient [49 CFR 173.301(d)];
  • The diamond hazard labels for the primary (and most subsidiary) hazard classes of the hazardous material [49 CFR 173.400, 173.402]. (2)

The DOT has very detailed specifications for hazard labels, but the Department does not specify formats for package markings, saying only that all package markings must be durable, visible, in English, and not obscured or confused by other markings.

A generator of hazardous waste can use a commercially available pre-printed label, such as our own  labels, or they may use any other means as long as the markings on the label conform to both the EPA and DOT requirements.
