Read the first 6 EMR Environmental Emergencies and Hazmat Awareness flashcards as text

  1. At a hazmat scene, the placard on a tanker shows the UN number 1017. What does this indicate to the EMR?

    Answer: The placard number helps identify the substance using the Emergency Response Guidebook

    UN numbers on placards correspond to specific substances in the Emergency Response Guidebook (ERG), allowing responders to identify hazards and safe actions.

  2. A patient is found near an overturned pesticide tanker, drooling, with miosis and muscle twitching. What class of agent is responsible?

    Answer: Organophosphate or nerve agent (cholinergic toxidrome)

    SLUDGE signs (Salivation, Lacrimation, Urination, Defecation, GI distress, Emesis) and miosis indicate cholinergic poisoning from organophosphates or nerve agents.

  3. What is the correct order of decontamination priorities for a contaminated victim at a hazmat scene?

    Answer: Remove and bag clothing, then flush with large amounts of water

    Removing clothing eliminates up to 80% of contamination, followed by copious water flushing — this sequence protects both the victim and responders.

  4. A patient who fell through ice into a frozen lake is pulled out. Their core temperature is estimated at 30°C (86°F). What rhythm disturbance is most concerning?

    Answer: Ventricular fibrillation

    Severe hypothermia (below 30°C) makes the myocardium highly susceptible to ventricular fibrillation, which is the primary lethal rhythm concern.

  5. When responding to a potential radiation emergency, the EMR's best protection follows the three principles of:

    Answer: Time, distance, and shielding

    Minimizing time of exposure, maximizing distance from the source, and using shielding are the three fundamental radiation protection principles.

  6. A swimmer is rescued and is breathing but unconscious after a submersion incident. The EMR should:

    Answer: Place in recovery position, monitor airway, and prepare for deterioration

    Post-submersion patients can deteriorate rapidly due to secondary drowning or aspiration; maintaining airway and close monitoring during transport is critical.
