Hazmat Placarding and Offering to the Carrier: 49 CFR 172.500
Every SOP generated from this template cites the paragraphs below, with a plain-language summary of what each one requires. Citations are informational and are not legal advice.
| Standard | Title | What it requires |
|---|---|---|
| 49 CFR 172.500 | Applicability of placarding requirements | Each person who offers for transportation or transports any hazardous material subject to the hazardous materials regulations must comply with the applicable placarding requirements of subpart F. The subpart does not apply to infectious substances, to hazardous materials authorized to be offered as a limited quantity when identified as such on a shipping paper or marked as such, to materials prepared under the small quantity and related exception provisions of the subchapter, or to combustible liquids in non-bulk packagings. |
| 49 CFR 172.101 | Purpose and use of the hazardous materials table | The Hazardous Materials Table designates the materials listed in it as hazardous materials for the purpose of transportation. For each listed material the Table identifies the hazard class or specifies that the material is forbidden in transportation, gives the proper shipping name, and specifies or references labeling, packaging, and related requirements. Column 3 contains the designation of the hazard class or division corresponding to each proper shipping name, or the word Forbidden. |
| 49 CFR 172.504 | General placarding requirements | Each bulk packaging, freight container, unit load device, transport vehicle, or rail car containing any quantity of a hazardous material must be placarded on each side and each end with the placards specified in Table 1 and Table 2 of the section, except as otherwise provided. For materials covered by Table 2 transported by highway or rail, placards are not required on a transport vehicle or freight container that contains less than 454 kg (1,001 pounds) aggregate gross weight of Table 2 materials; that exception does not extend to bulk packagings or to materials subject to the subpart's special placarding provisions. A vehicle with non-bulk packages of two or more Table 2 categories requiring different placards may display a DANGEROUS placard instead of the separate placards, but when 1,000 kg (2,205 pounds) aggregate gross weight or more of one category is loaded at one loading facility, the specific placard for that category must be applied. A non-bulk packaging containing only the residue of a Table 2 material need not be counted, and a CLASS 9 placard is not required for domestic transportation. |
| 49 CFR 172.506 | Providing and affixing placards: Highway | Each person offering a motor carrier a hazardous material for transportation by highway must provide to the motor carrier the required placards for the material being offered, prior to or at the same time the material is offered for transportation, unless the carrier's motor vehicle is already placarded for the material as required. No motor carrier may transport a hazardous material in a motor vehicle unless the required placards are affixed to it. |
| 49 CFR 172.502 | Prohibited and permissive placarding | No person may affix or display on a packaging, freight container, unit load device, motor vehicle, or rail car any placard described in the subpart unless the material being offered or transported is a hazardous material, the placard represents a hazard of the hazardous material being offered or transported, and the placarding conforms to the requirements of the subpart. Also prohibited is any sign, advertisement, slogan (such as Drive Safely), or device that by its color, design, shape, or content could be confused with a prescribed placard. Placards may be displayed for a hazardous material even when not required, if the placarding otherwise conforms to the subpart. |
| 49 CFR 172.516 | Visibility and display of placards | Each placard on a motor vehicle must be clearly visible from the direction it faces, and the required placarding of the front of a motor vehicle may be on the front of the truck tractor instead of or in addition to the front of the cargo body. Each placard must be securely attached or placed in a holder, located clear of appurtenances such as ladders, pipes, doors, and tarpaulins, located so far as practicable away from wheel spray, at least 3 inches away from any marking such as advertising that could reduce its effectiveness, displayed with its words or identification number horizontal reading left to right, and affixed to a background of contrasting color or bordered in contrast to the background. The placard must be maintained by the carrier in a condition so that its format, legibility, color, and visibility are not substantially reduced by damage, deterioration, or obscurement. |
Compliance checklist
What an inspector looks for
Placard requirements are determined from the completed shipping paper using the hazard class in Column 3 of the Hazardous Materials Table for every line item, including subsidiary hazards
49 CFR 172.101
Any quantity of a Table 1 material results in the specified placard on each side and each end of the vehicle, with no weight threshold applied
49 CFR 172.504
Table 2 materials are placarded when the aggregate gross weight on the vehicle reaches 454 kg (1,001 pounds), residue-only non-bulk packagings are not counted, and the exception is never applied to bulk packagings
49 CFR 172.504
A DANGEROUS placard is substituted for separate Table 2 placards only for non-bulk packages of two or more categories, and the specific placard is applied for any category loaded at 1,000 kg (2,205 pounds) or more at this facility
49 CFR 172.504
The required placards are provided to the motor carrier prior to or at the same time the shipment is offered, unless the vehicle is already correctly placarded, and the provision is recorded

No placard is displayed for a material that is not a hazardous material on the vehicle or that does not represent a hazard actually present, and no confusable sign or slogan is displayed

The offer-to-carrier handoff checklist, covering papers, emergency response information, placards, load compatibility, and package condition, is completed and signed before every hazmat load is released
