CDL Hazardous Materials Endorsement (HME)Emergencies and AccidentsEasy
A driver discovers a small fire in the cargo area of a trailer containing boxes placarded with 'ORM-D' (Other Regulated Materials - Domestic). The fire is confined to one box and appears to be igniting the packaging, not the product itself. What is the MOST appropriate initial action for the driver if it is safe to do so?
- ACover the burning box with a fire blanket to smother the flames.
- BAttempt to extinguish the fire using a fire extinguisher if trained and safe.
- COpen the trailer doors to ventilate the area and prevent heat buildup.
- DImmediately evacuate and call 911, awaiting emergency services.
Show answer & explanationAnswer & explanation
Correct answer: B. Attempt to extinguish the fire using a fire extinguisher if trained and safe.
ORM-D materials typically pose a relatively low hazard, similar to consumer commodities. If a small fire is confined and safe to approach, a driver trained in fire extinguisher use should attempt to extinguish it. Evacuating immediately for a minor ORM-D fire might be an overreaction if it's safely extinguishable, and ventilation could spread the fire.
Why the other options are wrong
- A. A fire blanket is an option, but a fire extinguisher is generally more effective for extinguishing small fires.
- C. Opening trailer doors can provide oxygen to the fire, potentially worsening it.
- D. While always an option, for a small ORM-D fire, immediate evacuation might not be the most effective first response if it's safely extinguishable.
ORM-D Fire Response
Initial actions for a small, contained fire involving ORM-D (Other Regulated Materials - Domestic), which are consumer commodities with relatively low hazard.
- ORM-D materials have limited hazard.
- Small fires can often be extinguished by the driver if safe.
- Prioritize safety, but don't overreact to minor incidents.
