  1. Which of the following best describes 'shelter-in-place' as a protective action during a hazmat release?

    Answer: Having people remain indoors with windows/doors closed to reduce exposure

    Shelter-in-place directs people to stay inside buildings with openings sealed to minimize exposure to outdoor contaminants.

  5. When responding to an unknown chemical spill, CAMEO (Computer-Aided Management of Emergency Operations) is primarily used to:

    Answer: Identify chemicals, model dispersion, and plan emergency responses

    CAMEO is a suite of software tools used to plan for and respond to chemical emergencies, including chemical identification and modeling.

  6. Which federal agency serves as the On-Scene Coordinator (OSC) for hazmat incidents occurring in coastal zones and inland navigable waterways?

    Answer: U.S. Coast Guard

    The U.S. Coast Guard serves as the federal OSC for coastal zone and navigable waterway hazmat incidents.

  7. A Material Safety Data Sheet (legacy) or Safety Data Sheet (GHS) Section 6 covers which emergency response topic?
