OIT Emergency Response and First Aid 2 — Questions and Answers
Question 1: A worker collapses and is unresponsive with no pulse. What is the correct compression-to-ventilation ratio for adult CPR with two rescuers?
- 30:2
- 15:2 (Correct answer)
- 10:2
- 5:1
Correct answer: 15:2
Two-rescuer adult CPR uses a 15:2 ratio, allowing more frequent ventilations with a second trained responder available.
Question 2: Which fire extinguisher class is appropriate for electrical equipment fires at an industrial facility?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Class C extinguishers use non-conductive agents and are rated for energized electrical equipment fires.
Question 3: An operator notices a coworker has a chemical splash in both eyes. What is the first action to take?
- Apply eye drops immediately
- Flush eyes with water for at least 15 minutes (Correct answer)
- Cover eyes with a sterile pad
- Transport to hospital without delay
Correct answer: Flush eyes with water for at least 15 minutes
Immediate flushing with water for a minimum of 15 minutes is the first priority for chemical eye exposure.
Question 4: Under OSHA's Hazard Communication Standard, what document provides first aid measures for a specific chemical?
- Emergency Response Guidebook (ERG)
- Safety Data Sheet (SDS) (Correct answer)
- Job Hazard Analysis (JHA)
- Process Safety Management Plan
Correct answer: Safety Data Sheet (SDS)
The Safety Data Sheet (SDS) Section 4 specifically covers first aid measures for each hazardous chemical.
Question 5: When using an AED, what must you do immediately before delivering a shock?
- Start chest compressions
- Ensure no one is touching the patient (Correct answer)
- Check for a pulse
- Apply supplemental oxygen
Correct answer: Ensure no one is touching the patient
All rescuers must stand clear of the patient before AED shock delivery to prevent accidental electrocution.
Question 6: A pressure relief valve on a vessel vents unexpectedly. What is the operator's first emergency response priority?
- Reset the relief valve manually
- Evacuate the immediate area and notify supervision (Correct answer)
- Increase feed rate to stabilize pressure
- Log the event and continue normal operations
Correct answer: Evacuate the immediate area and notify supervision
Unexpected relief valve activation indicates an overpressure event; evacuation and notification are the immediate priorities.
Question 7: Which type of wound requires the most immediate concern for tetanus infection in an industrial setting?
- Clean shallow cut
- Puncture wound from a rusty nail (Correct answer)
- Superficial abrasion
- Minor burn
Correct answer: Puncture wound from a rusty nail
Deep puncture wounds, especially from rusty or contaminated objects, carry the highest risk of tetanus infection.
A worker collapses and is unresponsive with no pulse.
