FRA Hazardous Materials Transportation 3

Question 1

A railroad employee discovers a leaking tank car of anhydrous ammonia. What is the FIRST action required under FRA/DOT incident response rules?

Accepted Answer

Notify the emergency contact number on the shipping paper and isolate the area

Answer

The immediate priority is to isolate the hazard and notify emergency responders via the 24-hour emergency contact number listed on the shipping paper.

Question 2

Which packing group designation indicates the HIGHEST degree of danger for a hazardous material?

Accepted Answer

Packing Group I

Answer

Packing Group I (PG I) designates materials presenting the greatest danger, requiring the most stringent packaging standards.

Question 3

Under 49 CFR Part 174, where must hazmat shipping papers be kept while a train is in motion?

Accepted Answer

In a holder or location readily accessible to the train crew in the locomotive cab

Answer

Shipping papers must be immediately accessible to the train crew in the locomotive cab so they can be retrieved quickly during an emergency.

Question 4

What does the 'Z' suffix after a UN number on a shipping paper indicate?

Accepted Answer

The material is a marine pollutant

Answer

A 'Z' suffix (e.g., UN1234Z) is not standard; however, the marine pollutant designation (M) is a common modifier—but under DOT rules the 'RQ' prefix signals a reportable quantity, not 'Z'.

Question 5

Which federal agency has primary regulatory jurisdiction over hazardous materials transportation by rail in the United States?

Accepted Answer

PHMSA and FRA jointly

Answer

The Pipeline and Hazardous Materials Safety Administration (PHMSA) sets hazmat transport regulations, while the FRA enforces railroad safety compliance.
