  1. An operator working with hydraulic systems develops sudden severe eye pain after a suspected high-pressure injection injury with no visible wound. The correct action is:

    Answer: Seek emergency medical care immediately — high-pressure injection is a surgical emergency

    High-pressure injection injuries appear minor but cause severe internal tissue damage requiring immediate surgical intervention.

  2. During a gas leak emergency, which action should an operator take FIRST before any other response?

    Answer: Eliminate all ignition sources and evacuate upwind

    Eliminating ignition sources and evacuating upwind are the first priorities to prevent explosion and protect personnel.

  3. What is the purpose of a tourniquet in emergency first aid for an industrial amputation injury?

    Answer: Control life-threatening arterial bleeding when direct pressure fails

    A tourniquet is used to stop severe arterial hemorrhage when direct pressure cannot control life-threatening bleeding.

  4. An operator is exposed to a corrosive acid on their skin. How long should the affected area be flushed with water?

    Answer: At least 20 minutes

    OSHA and ANSI recommend a minimum of 20 minutes of continuous water flushing for corrosive skin exposures.

  5. Which symptom combination is most characteristic of heat stroke (not heat exhaustion) in an industrial worker?

    Answer: Hot dry skin, confusion, and body temperature above 104°F

    Heat stroke presents with hot dry skin, altered mental status, and dangerously elevated core temperature — a life-threatening emergency.

  6. What information must be provided to emergency services (911) when reporting an industrial chemical release?

    Answer: Chemical name, quantity released, and number of injured personnel

    Emergency responders need the chemical identity, estimated quantity, and casualty count to dispatch appropriate resources and prepare treatment.

  7. A spill of flammable solvent ignites in a process area. Which action is INCORRECT?

    Answer: Open windows to ventilate the area

    Opening windows in a flammable vapor fire can increase oxygen supply and spread vapors to new ignition sources, worsening the fire.
