- The company's insurance carrier
- The most senior employee present
- The designated Incident Commander (Correct answer)
Correct answer: The designated Incident Commander
Under the Incident Command System, the Incident Commander holds primary accountability for all aspects of the emergency response, including strategy and resource use.
Question 2: What is the 'hot zone' in a hazmat incident response?
- The area where the media is briefed
- The command post location
- The decontamination corridor
- The area of highest contamination where entry requires full protective equipment (Correct answer)
Correct answer: The area of highest contamination where entry requires full protective equipment
The hot zone is the area of highest contamination immediately surrounding a hazmat incident, where only personnel with appropriate PPE may enter.
Question 3: Which route of entry is typically the primary concern for most airborne industrial chemicals?
- Dermal absorption
- Ingestion
