According to 49 CFR 172, how many pounds of hazardous materials can be transported without a placard?

• A. 220 lbs
• B. 330 lbs
• C. 440 lbs
• D. 550 lbs

Answer: (C)

The correct understanding of the regulations under 49 CFR 172 indicates that hazardous materials can be transported without a placard up to a threshold of 440 pounds. This regulation is essential for maintaining safety and clarity in the transport of hazardous materials, ensuring that emergency responders are aware of potential risks without having to guess the nature of the cargo. The 440-pound limit establishes a clear policy where shipments below this weight do not necessitate the display of placards, allowing for easier movement of non-threatening loads while still retaining the necessary precautions. This understanding is crucial for compliance and safety in the transportation of hazardous materials, particularly for first responders who may need to intervene in case of incidents. The other weight limits stated in the options either exceed or fall below this threshold and do not reflect the established guidelines, hence reinforcing the importance of knowing the correct limit for proper regulation and safety compliance.
