HMR Placarding Table 1

Table 1 lists hazardous materials by category for which placarding is required for any quantity of material contained in the freight container, unit load device, transport vehicle, or rail car. No material listed in Table 1 is duplicated in Table 2. Each material will be exclusive to one table.

Table 1 lists the required placard and the section reference number for the following classes and divisions of hazardous material:

• Division 1.1
• Division 1.2
• Division 1.3
• Division 2.3
• Division 5.2
• Division 6.1
• Class 7

Placarding requirements for hazard division numbers 5.2 and 6.1 are divided between Table 1 and Table 2 based on additional description information.

• All Division 5.2, Type B liquid, or solid, temperature-controlled organic peroxides are covered by Table 1, while all the other Division 5.2, organic peroxides are covered by Table 2.
• All Division 6.1, Inhalation hazard, Zone A or B material is covered by Table 1 and placarded with the Poison Inhalation Hazard placard. All other Division 6.1 materials are covered by Table 2 and placarded with the Poison placard.

Not all Class 7 radioactive materials require placarding. The exception for Class 7 in Table 1 states that placarding is required for "Radioactive Yellow-III label only." The footnote to Table 1 notes that a placard is also required for exclusive-use shipments of low-specific-activity material and surface contaminated objects when shipped in accordance with 49 CFR §173.427. Placards are not required for radioactive material labeled White-I or Yellow-II.
