CHMM Planning for Hazardous Materials 5 — Questions and Answers
Question 1: The National Response Framework (NRF) is built on which foundational incident management system that provides a standardized approach to command, control, and coordination?
- Emergency Support Function (ESF) structure
- Incident Command System (ICS) within NIMS (Correct answer)
- Unified Command Protocol (UCP)
- Federal Emergency Management System (FEMS)
Correct answer: Incident Command System (ICS) within NIMS
The NRF is grounded in NIMS, which uses ICS as its core incident management structure to ensure interoperability across all responding agencies.
Question 2: Under RCRA, generators of hazardous waste must maintain a contingency plan that addresses all of the following EXCEPT:
- Emergency coordinator contact information
- Emergency equipment list and its location
- Evacuation plan for facility personnel
- A five-year financial assurance projection for cleanup costs (Correct answer)
Correct answer: A five-year financial assurance projection for cleanup costs
RCRA contingency plans address emergency response procedures, coordinator contacts, equipment inventories, and evacuation — financial assurance projections are not a contingency plan element.
Question 3: In developing a facility emergency response plan, a 'consequence analysis' is used to:
- Determine the likelihood that a specific emergency scenario will occur
- Estimate the potential impacts — on people, environment, and property — of a hazardous material release (Correct answer)
- Calculate the regulatory fines associated with a reportable release
- Identify which employees are responsible for emergency response actions
Correct answer: Estimate the potential impacts — on people, environment, and property — of a hazardous material release
Consequence analysis evaluates the magnitude of harm from a hypothetical release scenario, informing protective action planning and resource allocation.
Question 4: Which section of the Emergency Planning and Community Right-to-Know Act (EPCRA) requires facilities to report accidental releases of extremely hazardous substances and CERCLA hazardous substances?
- Section 302
- Section 304 (Correct answer)
- Section 311
- Section 313
Correct answer: Section 304
EPCRA Section 304 requires immediate notification to the SERC and LEPC whenever a reportable quantity of an EHS or CERCLA hazardous substance is released.
Question 5: When selecting personal protective equipment for a hazardous materials incident where the chemical identity is unknown, the initial responding hazmat team should use:
- Level C protection with air-purifying respirators
- Level B protection as a minimum until the substance is identified (Correct answer)
- Level D protection with monitoring equipment only
- Level A protection regardless of available monitoring data
Correct answer: Level B protection as a minimum until the substance is identified
Level B is the minimum acceptable starting protection for unknown hazards because it provides supplied-air protection while allowing greater mobility than Level A.
Question 6: A shelter-in-place order is most appropriate when:
- The release is immediately life-threatening and evacuation cannot be completed before exposure (Correct answer)
- The release involves a flammable gas that could ignite inside occupied buildings
- There are sufficient evacuation routes available for all affected residents
- The incident is expected to last more than 24 hours
Correct answer: The release is immediately life-threatening and evacuation cannot be completed before exposure
Shelter-in-place is preferred when evacuation would expose people to the hazard longer than staying indoors with windows and doors sealed.
Question 7: Which federal agency publishes the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), which serves as the regulatory framework for responding to oil spills and hazardous substance releases under CERCLA?
- OSHA
- EPA (Correct answer)
- FEMA
- DOT/PHMSA
Correct answer: EPA
EPA promulgates and maintains the NCP (40 CFR Part 300), which establishes the national response system and procedures for oil and hazardous substance incidents.
