A driver is transporting a portable tank containing UN1978, Propane, Class 2.1. The tank has the appropriate placards and identification numbers. What additional information must be available to emergency responders in case of an incident?
- AA copy of the driver's medical certificate.
- BEmergency Response Information (ERI) for Propane.
- CA detailed invoice of the material's cost and origin.
- DThe shipper's internal tracking number for the tank.
Show answer & explanationAnswer & explanation
Correct answer: B. Emergency Response Information (ERI) for Propane.
In addition to shipping papers, placards, and markings, emergency response information (ERI) is a mandatory communication requirement for hazardous materials transport. This information, often found in an Emergency Response Guidebook (ERG), provides guidance on what to do in case of spills, fires, or exposures involving the specific hazardous material (49 CFR 172.602).
Why the other options are wrong
- A. A driver's medical certificate is a licensing requirement, not emergency response information for the cargo.
- C. Financial details are not emergency response information.
- D. Internal tracking numbers are not part of mandatory emergency response information.
Emergency Response Information (ERI)
Emergency Response Information (ERI) provides immediate guidance on how to handle spills, fires, or exposures involving hazardous materials, and must be readily available during transport.
- Required by 49 CFR 172.602.
- Often provided via an Emergency Response Guidebook (ERG).
- Critical for first responders.
Memory trick: HazMat's danger, quick to react, ERG's the guide, for safety's pact.
