First Aid Workplace Safety 3 — Questions and Answers
Question 1: A worker collapses in a warehouse and is unresponsive with no normal breathing. The AED arrives. What is the correct order of actions?
- AED first, then CPR
- Call 911, start CPR, use AED as soon as available (Correct answer)
- Wait for paramedics before starting any intervention
- Give rescue breaths only until the AED arrives
Correct answer: Call 911, start CPR, use AED as soon as available
The chain of survival requires calling 911, starting CPR immediately, and using the AED as soon as it is available.
Question 2: Which hazard class does 'fall from elevation' belong to under OSHA's Fatal Four?
- Caught-in/between
- Struck-by
- Falls (Correct answer)
- Electrocution
Correct answer: Falls
Falls are one of OSHA's Fatal Four leading causes of construction fatalities and include falls from scaffolding, ladders, and roofs.
Question 3: An employee begins showing signs of heat exhaustion—heavy sweating, weakness, and cool clammy skin. What is the priority first aid step?
- Give the worker aspirin
- Move them to a cool area and provide cool water to sip (Correct answer)
- Apply ice packs directly to the skin
- Have them continue light work to stay moving
Correct answer: Move them to a cool area and provide cool water to sip
Moving to a cool environment and hydrating with cool water are the first steps to prevent progression to heat stroke.
Question 4: What is the minimum safe distance from power lines that unqualified workers must maintain, according to OSHA?
- 3 feet
- 6 feet
- 10 feet (Correct answer)
- 25 feet
Correct answer: 10 feet
OSHA requires unqualified workers to maintain at least a 10-foot distance from overhead power lines up to 50 kV.
Question 5: A coworker is struck in the head by a falling tool and loses consciousness briefly. Which response is most appropriate?
- Have the worker walk it off to assess stability
- Assume the injury is minor and monitor from a distance
- Keep the worker still, assume a possible spinal injury, and call EMS (Correct answer)
- Perform a head tilt-chin lift to check airway immediately
Correct answer: Keep the worker still, assume a possible spinal injury, and call EMS
Loss of consciousness after a head strike indicates potential spinal involvement; keep the worker immobilized and activate EMS.
Question 6: Which personal protective equipment (PPE) is required when working with bloodborne pathogens during first aid?
- Hard hat and safety boots
- Gloves and eye protection at minimum (Correct answer)
- Hearing protection and a respirator
- High-visibility vest and knee pads
Correct answer: Gloves and eye protection at minimum
OSHA's Bloodborne Pathogens Standard requires gloves and eye protection as minimum PPE when exposure to blood is possible.
Question 7: What does 'lockout/tagout' (LOTO) protect workers from?
- Chemical spills during maintenance
- Unexpected energization of machinery during servicing (Correct answer)
- Falls from elevated work platforms
- Noise-induced hearing loss
Correct answer: Unexpected energization of machinery during servicing
LOTO procedures ensure machinery cannot be accidentally energized while workers are performing maintenance or servicing tasks.
