DOT Hazard Placards and Signs at ComplianceSigns

Our placards are available in a variety of sizes including DOT standard 10.75 x 10.75 inches, as well as other sizes for other uses. All are designed to meet DOT specifications 49 CFR 172.407(c) for labels or 49 CFR 172.519(c) for placards. All our DOT placards resist UV, chemicals, abrasion and moisture for long life.

What to Know About Chemical Placards

The DOT requires chemical placards for all carriers transporting hazardous materials by road. Carriers must ensure proper placard placement and compliance with DOT regulations, as identified in Hazardous Materials Regulations (HMR; 49 CFR Parts 171-185). See 49 CFR, Part 172, Subpart F, for complete placarding regulations, or Subpart E for labeling regulations.

Placards typically include a hazard classification number, UN or NA number, compatibility letters, defined colors, signal words and graphics.

Hazard Class Numbers:

Class 1 - Explosives
Class 2 - Gases
Class 3 - Flammable or Combustible Liquids
Class 4 - Flammable Solids
Class 5 - Oxidizers & Organic Peroxides
Class 6 - Poisons (Toxic)
Class 7 - Radioactive
Class 8 - Corrosive
Class 9 - Miscellaneous
DANGEROUS - for some instances when transporting packages with two or more categories of hazardous materials

Hazmat Placard Colors:

Orange - Explosive
Red - Flammable
Green - Non-flammable
Yellow - Oxidizers that are likely to combust when mixed with oxygen
White - Poisonous and bio-hazardous
Blue - Can become flammable when combined with water
Red / White - Can ignite when exposed to air
Red / White Stripes - Flammable solids
Red / Yellow - Organic peroxides that can ignite or explode
Yellow / White - Radioactive
White / Black - Corrosive
White / Black Stripes - Dangerous goods including non-classified, environmentally hazardous substances

UN and NA Numbers:

UN (United Nations) Numbers are four-digit numbers used to identify hazardous chemicals or classes of hazardous materials worldwide. NA (North American) Numbers are identical to UN numbers. If a material does not have a UN number, it may be assigned an NA number.

These numbers are used by first responders to identify materials, using a list in the U.S. DOT Emergency Response Guidebook (ERG).

In addition to hazard class, color and UN numbers, placards may also include specific hazard terms and illustrations to indicate specific dangers.
