CHMM - Certified Hazardous Materials Manager Emergency Response and Recovery Questions and Answers

Question 1

During a large chemical spill at a manufacturing plant, the senior fire chief, the facility's emergency response manager, and a state environmental protection official are all on-scene with command authority. To ensure effective and coordinated management of the incident, which structure should be implemented under the National Incident Management System (NIMS)?

Accepted Answer

A Unified Command where all agency leaders jointly make decisions.

Answer

Unified Command is a NIMS structure used when multiple jurisdictions or agencies have responsibility for an incident. It brings together the Incident Commanders from the major organizations to coordinate an effective response, establish a common set of objectives, and share in decision-making, without any single agency losing its own authority.

Question 2

An employee who is part of an organized emergency response team is expected to take defensive actions, such as closing valves or deploying absorbent booms, to contain a release from a safe distance. This employee does not approach the point of release. According to OSHA's HAZWOPER standard (29 CFR 1910.120(q)), what is the minimum level of training required for this individual?

Accepted Answer

First Responder Operations Level

Answer

The First Responder Operations Level is for individuals who respond to releases for the purpose of protecting nearby persons, property, or the environment from the effects of the release. Their function is to contain the release from a safe distance, keep it from spreading, and prevent exposures. This level requires at least 8 hours of training.

Question 3

A CHMM is reviewing a Large Quantity Generator's (LQG) RCRA Contingency Plan. Which of the following elements is specifically required to be included in the plan according to 40 CFR 262, Subpart M?

Accepted Answer

An evacuation plan for facility personnel, including signals and routes.

Answer

According to 40 CFR § 262.261(f), a RCRA Contingency Plan for a Large Quantity Generator must include an evacuation plan for facility personnel where there is a possibility that evacuation could be necessary. This plan must describe the signal(s) to be used to begin evacuation and detail primary and alternate evacuation routes.

Question 4

What is the primary purpose of performing decontamination procedures on personnel during a hazardous materials emergency response?

Accepted Answer

To prevent the transfer of harmful materials into clean areas and protect responders from exposure.

Answer

The critical purpose of decontamination is to remove or neutralize contaminants from personnel and equipment. This protects workers from ongoing exposure, prevents the spread of contamination beyond the exclusion zone (cross-contamination), helps prevent the mixing of incompatible chemicals, and protects the community.

Question 5

A facility in the U.S. has an accidental, off-site release of a CERCLA hazardous substance in a quantity that exceeds its Reportable Quantity (RQ). The substance is also listed as an EPCRA Extremely Hazardous Substance (EHS). Which immediate notifications are required?

Accepted Answer

The National Response Center (NRC), the SERC, and the LEPC.

Answer

A release of a substance that exceeds the RQ under CERCLA requires immediate notification to the National Response Center (NRC). If that same substance is also an EPCRA EHS and is released in a reportable quantity, EPCRA Section 304 requires immediate notification to the State or Tribal Emergency Response Commission (SERC/TERC) and the Local or Tribal Emergency Planning Committee (LEPC/TEPC). Therefore, both sets of notifications are required.
