Correct answer: Yellow with a flame over a circle
Class 5.1 Oxidizer placards are yellow with a flame-over-circle symbol, reflecting the material's ability to accelerate combustion.
Question 2: A forklift operator must transport a pallet labeled 'ORM-D' (Other Regulated Materials – Domestic). What does this designation indicate?
- The material requires full hazmat placarding on all sides
- It is a consumer commodity with limited hazmat regulation (Correct answer)
- It is exempt from all DOT transportation requirements
- It must be transported only by licensed hazmat drivers
Correct answer: It is a consumer commodity with limited hazmat regulation
ORM-D materials are consumer commodities that present limited hazard and are subject to reduced DOT packaging and labeling requirements.
Question 3: The four-digit UN/NA identification number on a hazmat placard or orange panel is used primarily to:
- Indicate the weight limit for the shipment
- Identify the specific hazardous material for emergency responders (Correct answer)
- Show the country of origin of the substance
- Confirm the carrier's authorization to transport hazmat
Correct answer: Identify the specific hazardous material for emergency responders
The UN/NA number uniquely identifies the hazardous substance, enabling emergency responders to quickly look up the correct response procedures.
Question 4: Class 6.2 Infectious Substance placards display which symbol?

Class 6.2 Infectious Substances use a white placard with the universal biohazard symbol to warn of biological hazard.
Question 5: When stacking hazmat pallets on a forklift, which factor related to placarding must be maintained?

- All placards must remain visible and unobstructed from each required direction (Correct answer)
- Only the top pallet's placard needs to be visible
- Placards may be removed temporarily during stacking operations
Correct answer: All placards must remain visible and unobstructed from each required direction
DOT requires placards to be visible from the direction they face; stacking must not block required placard visibility.
