25 practice questions

1. The OSHA regulation that sets training and safety rules for workers who respond to hazardous materials releases is:

   1. A. 29 CFR 1910.120, known as HAZWOPER
   2. B. 29 CFR 1910.1030, the bloodborne rule
   3. C. 49 CFR 172, the DOT placarding rule
   4. D. 40 CFR 302, the EPA reporting rule
   Show answer

   Answer: A. 29 CFR 1910.120, known as HAZWOPER

   HAZWOPER (Hazardous Waste Operations and Emergency Response) sets OSHA's training levels, PPE, medical surveillance, and response-plan rules for hazmat responders. The bloodborne pathogens standard is the common mix-up because it is also an OSHA rule, but it covers infection control, not chemical releases.

2. A volunteer EMS agency operates in a state with no OSHA-approved plan for public employees. Its members are held to the same hazmat training rules through:

   1. A. The DOT Emergency Response Guidebook
   2. B. NFPA 1500 on safety
   3. C. EPA regulation 40 CFR 311
   4. D. The state's EMS scope of practice
   Show answer

   Answer: C. EPA regulation 40 CFR 311

   OSHA does not directly cover state and local public employees in states without an approved plan, so the EPA adopted the HAZWOPER requirements for them in 40 CFR 311. The ERG is a field reference, not a training regulation.

3. A paramedic trained only to the awareness level arrives first at an overturned tank truck that is leaking a liquid. Which action is within her training?

   1. A. Dike the spill downhill to slow its spread
   2. B. Read the placard and look it up in the ERG
   3. C. Shut the leaking valve while wearing SCBA
   4. D. Set up a decon line and wash the driver
   Show answer

   Answer: B. Read the placard and look it up in the ERG

   OSHA's awareness level (29 CFR 1910.120(q)(6)(i)) covers recognizing a release, identifying the material if possible from a safe distance, using the DOT Emergency Response Guidebook, securing the area, and calling for the right help. Reading the placard or ID number from a safe distance, with binoculars if needed, and looking it up in the ERG is therefore within her role. Building a dike is a defensive control task that needs operations-level training. Closing the valve is offensive work at the point of release, which belongs to hazmat technicians in chemical protective clothing; SCBA protects the lungs, not the skin. Setting up and running decon is an operations-level, mission-specific task done in PPE, not an awareness-level job.

4. You are trained to the hazmat operations level. At a warehouse, a drum is leaking a liquid toward a storm drain. An appropriate action for you is to:

   1. A. Close the drum's bung in a splash suit
   2. B. Overpack the drum in a Level A suit
   3. C. Neutralize the spill with an absorbent
   4. D. Block the drain from a safe distance
   Show answer

   Answer: D. Block the drain from a safe distance

   Operations-level responders take defensive actions, such as diking, damming, or covering a drain away from the point of release, to protect people and the environment. Closing or overpacking the leaking container is offensive action that requires technician training.

5. The key difference between the hazmat technician and operations levels is that technicians:

   1. A. Take offensive action to stop a release
   2. B. Protect nearby people from a safe distance
   3. C. Recognize a release and notify others
   4. D. Serve as liaison with federal agencies
   Show answer

   Answer: A. Take offensive action to stop a release

   Technicians approach the point of release to plug, patch, or otherwise stop it, which is offensive action. Protecting nearby people from a distance is the operations-level role, and liaison with outside agencies is typical of the specialist.

6. A hazmat specialist differs from a technician mainly by having:

   1. A. Authority to take command of the whole incident
   2. B. Training limited to recognition and notification
   3. C. Approval to give antidotes inside the hot zone
   4. D. Deep knowledge of certain agents or containers
   Show answer

   Answer: D. Deep knowledge of certain agents or containers

   Specialists have advanced, often product- or container-specific knowledge and support technicians and command, sometimes as liaison with other agencies. Command authority comes from the incident command structure, not from the specialist training level.

7. At a minimum, any EMS provider who might come upon a hazmat release in the course of work should be trained to the:

   1. A. Operations level
   2. B. Technician level
   3. C. Awareness level
   4. D. Specialist level
   Show answer

   Answer: C. Awareness level

   Anyone likely to discover a release must be able to recognize it, protect themselves, and call for help, which is the awareness level. Many agencies train EMS to the operations level, which is the tempting answer, but awareness is the minimum; technician and specialist training is for those who act on the release itself.

8. NFPA 470, first issued in 2022, matters to EMS because it:

   1. A. Sets the colors and numbers used on fixed-facility diamonds
   2. B. Combines hazmat competencies, EMS included, in one standard
   3. C. Defines rehab criteria for crews on extended incidents
   4. D. Replaces OSHA HAZWOPER as the legal training requirement
   Show answer

   Answer: B. Combines hazmat competencies, EMS included, in one standard

   NFPA 470 merged the former NFPA 472 (responder competencies) and NFPA 473 (EMS competencies) into a single standard. NFPA standards are consensus documents; they do not replace OSHA law, and the hazard diamond is NFPA 704.

9. Your paramedic team is assigned to treat patients in the warm zone before decontamination is finished. Under the EMS levels of NFPA 473 (now part of NFPA 470), this role calls for training at:

   1. A. EMS hazmat Level I
   2. B. The awareness level
   3. C. The specialist level
   4. D. EMS hazmat Level II
   Show answer

   Answer: D. EMS hazmat Level II

   EMS Level I responders care for patients in the cold zone who pose little risk of secondary contamination. Level II responders are trained to work in the warm zone, care for patients who may still be contaminated, oversee decon, and medically monitor the entry team. Awareness training covers recognition, isolation, and notification and does not prepare anyone to work in the warm zone. Specialist is an OSHA response level for people with product or container expertise, not an EMS patient care level. NFPA 470 (2022) absorbed NFPA 473's EMS competencies, and local protocols may use its newer chapter titles.

10. Under SARA Title III, the group responsible for writing the community's chemical emergency response plan is the:

    1. A. State fire marshal's hazmat bureau
    2. B. Local emergency planning committee
    3. C. Regional poison control center
    4. D. Hospital emergency management office
    Show answer

    Answer: B. Local emergency planning committee

    The Emergency Planning and Community Right-to-Know Act (SARA Title III, 1986) created local emergency planning committees (LEPCs), which use facility chemical reports to plan for releases. Fire officials and poison centers may take part, but the plan belongs to the LEPC.

11. Before a joint drill with the hospital, your EMS supervisor wants to know which chemicals are stored at a nearby plant. The most useful source is the plant's:

    1. A. Tier II chemical inventory report
    2. B. Most recent OSHA injury and illness log
    3. C. Shipping papers from its last delivery
    4. D. Annual fire sprinkler inspection report
    Show answer

    Answer: A. Tier II chemical inventory report

    Facilities that store reportable amounts of hazardous chemicals file Tier II inventory reports each year with the LEPC, the state, and the local fire department, which supports preincident planning. Shipping papers from the last delivery cover only that one shipment, not everything stored on site. The OSHA injury and illness log records worker injuries, not chemicals on hand. A fire sprinkler inspection report covers the fire protection system, not the chemical inventory.

12. HAZWOPER requires that hazmat responders complete refresher training or show competency:

    1. A. Every 2 years
    2. B. Every 4 years, with each new ERG
    3. C. At least once a year
    4. D. Once, at the time of initial hire
    Show answer

    Answer: C. At least once a year

    OSHA requires annual refresher training, or documented proof of competency, so rarely used skills stay current. The ERG is revised about every 4 years, which is the tempting distractor, but that cycle does not set training frequency.

13. An operations-level responder may do added tasks, such as technical decon or victim rescue, after extra training. NFPA calls these:

    1. A. Technician-level endorsements
    2. B. Specialist product credentials
    3. C. Awareness-plus certifications
    4. D. Mission-specific competencies
    Show answer

    Answer: D. Mission-specific competencies

    NFPA lets the authority having jurisdiction assign operations-level responders specific missions, such as PPE use, decon, product control, or evidence preservation, once they are trained for them. These responders remain at the operations level; they are not technicians.

14. Under HAZWOPER, the on-scene incident commander at a hazmat release must have:

    1. A. Operations and incident command training
    2. B. Technician training plus a degree in chemistry
    3. C. Awareness training and 5 years of experience
    4. D. Specialist training in the product involved
    Show answer

    Answer: A. Operations and incident command training

    OSHA requires the incident commander to be trained to at least the operations level and in the incident command system and the employer's response plan. Product expertise is not required of the commander; specialists and technical references advise command.

15. OSHA requires that members of an organized hazmat team receive:

    1. A. A one-time exam at hire with no follow-up
    2. B. Exams after reported exposures, not routinely
    3. C. Baseline and periodic medical exams
    4. D. Yearly blood levels for each stored chemical
    Show answer

    Answer: C. Baseline and periodic medical exams

    HAZWOPER medical surveillance includes an exam before assignment and periodic exams, usually yearly, to detect health problems and the effects of exposures over time. On-scene pre-entry vital signs are a separate check and do not replace this program. A single exam at hire misses effects that develop over years, and exams limited to reported exposures miss exposures nobody recognized. Routine blood levels for every stored chemical are not required; tests are chosen by the physician based on each member's exposure risk.

16. Which task is a typical EMS responsibility at a hazmat incident?

    1. A. Choosing the agent used to control the spill
    2. B. Medical monitoring of entry team members
    3. C. Directing the tactics of the entry team
    4. D. Plugging the leak once a suit is donned
    Show answer

    Answer: B. Medical monitoring of entry team members

    EMS commonly provides pre- and post-entry medical monitoring, rehab, and care for patients after decon. Tactical decisions and leak control belong to the hazmat group and its technicians.

17. The main reason EMS crews should not rush in to rescue victims at a hazmat release is that:

    1. A. Victims in the hot zone usually die before help arrives
    2. B. Most victims can walk out of the area without help
    3. C. Contaminated rescuers become patients and spread it
    4. D. Police must first identify each victim for legal reasons
    Show answer

    Answer: C. Contaminated rescuers become patients and spread it

    Unprotected rescuers who enter a release often become casualties, which removes them as resources and can carry contamination to the ambulance and hospital. Many victims do survive, so the answer is a trained, protected entry, not giving up on them.

18. A facility releases a chemical above its federal reportable quantity. Federal law requires the release be reported to the:

    1. A. National Response Center
    2. B. Regional poison control center
    3. C. Nearest Level I trauma center
    4. D. State EMS office
    Show answer

    Answer: A. National Response Center

    Releases at or above a reportable quantity must be reported to the National Response Center, staffed by the US Coast Guard, which alerts the federal agencies involved. Poison control gives medical advice but is not the federal notification point.

19. As defined by the US Department of Transportation, a hazardous material is any substance that:

    1. A. Is known to cause cancer in people or in animals
    2. B. Has a flash point below normal room temperature
    3. C. Is a gas stored in cylinders under high pressure
    4. D. Can harm health, safety, or property in transport
    Show answer

    Answer: D. Can harm health, safety, or property in transport

    DOT defines hazardous materials broadly as substances that can pose an unreasonable risk to health, safety, and property when transported in commerce. Carcinogens, flammable liquids, and compressed gases are examples, but none alone is the definition.

20. A trucking company's drivers sometimes help at roadside chemical spills. For hazmat in transport, placarding and shipping paper rules are set by:

    1. A. The EPA
    2. B. The Department of Transportation
    3. C. The Occupational Safety and Health Administration
    4. D. The National Fire Protection Association
    Show answer

    Answer: B. The Department of Transportation

    DOT, through the Pipeline and Hazardous Materials Safety Administration (49 CFR), regulates how hazmat is classified, packaged, placarded, and documented in transport. OSHA governs workplace safety and responder training, and NFPA writes voluntary consensus standards.

21. Under OSHA's Hazard Communication Standard, which is aligned with the Globally Harmonized System, employers must:

    1. A. Post a placard on each storage room with a UN number
    2. B. Train employees to the hazmat technician level
    3. C. Report stock to poison control
    4. D. Label chemicals and keep SDSs available
    Show answer

    Answer: D. Label chemicals and keep SDSs available

    The Hazard Communication Standard requires labels with standard pictograms, accessible safety data sheets, and worker training on the chemicals they use. Placards and UN numbers are DOT transport markings, and most workers need hazard training, not technician certification.

22. Under HAZWOPER, an employer whose workers will respond to hazmat releases must have:

    1. A. A written emergency response plan
    2. B. A decon trailer at each work site
    3. C. A physician on scene at each release
    4. D. Level A suits for its employees
    Show answer

    Answer: A. A written emergency response plan

    OSHA requires a written plan covering roles, training, communication, PPE, decon, medical care, and evacuation before workers respond. Specific equipment levels, such as Level A suits for everyone, are not required; the plan matches equipment to the expected hazards.

23. A hazmat team is about to send two members into the hot zone. OSHA rules for this entry require:

    1. A. One member who enters alone with a radio
    2. B. A buddy system with a backup team ready
    3. C. A paramedic who enters with the team
    4. D. A physician who signs off on the entry
    Show answer

    Answer: B. A buddy system with a backup team ready

    Entrants in the hot zone must work in pairs, and a backup team in equal PPE must be ready to rescue them, with EMS standing by. A paramedic does not enter unless trained and assigned; the backup team, not EMS, makes the rescue.

24. You are first on scene at a pipeline leak with a strong odor and no patients. When you request hazmat resources, the most useful details to give are:

    1. A. The odor and the color of the visible vapor
    2. B. The pipeline owner's name and phone number
    3. C. Location, wind direction, and any ID numbers
    4. D. The nearest hydrant and the road surface conditions
    Show answer

    Answer: C. Location, wind direction, and any ID numbers

    Responding units need to know where the release is, how they can approach it from upwind, and what the product might be, so ID numbers, placards, or markers from a safe distance are key. Odor and vapor color are poor and dangerous ways to identify a chemical, and many toxic gases are colorless. Hydrants and road conditions matter less to arriving units than the product and a safe upwind approach, and the pipeline operator's contact details can be obtained by dispatch or found on the line markers.

25. A paramedic on her agency's organized hazmat team is splashed with an unknown liquid through a torn suit during an entry. Under HAZWOPER, the employer must:

    1. A. Wait for symptoms before an evaluation
    2. B. Schedule the next routine yearly physical
    3. C. Provide a medical exam as soon as possible
    4. D. Remove the paramedic from the hazmat roster
    Show answer

    Answer: C. Provide a medical exam as soon as possible

    Hazmat team members are covered by HAZWOPER medical surveillance, which requires an exam as soon as possible after an employee is injured or possibly overexposed in an emergency, so delayed effects are found early and documented (29 CFR 1910.120(f)(3)(i)(C) and (q)(9)(i)). Waiting for symptoms is the tempting choice; that trigger applies to responders outside the team, and many chemicals cause delayed injury. The next routine yearly physical comes far too late to evaluate an acute exposure. Removing her from the roster is not required and does nothing to evaluate the exposure.
