First Aid Workplace Safety 5 — Questions and Answers
Question 1: A worker is unresponsive, and you have confirmed no pulse. The AED analyzes the rhythm and says 'No shock advised.' What should you do?
- Stop and wait for EMS to arrive
- Resume CPR immediately and continue until EMS arrives (Correct answer)
- Reattach AED pads and reanalyze immediately
- Deliver a precordial thump to the chest
Correct answer: Resume CPR immediately and continue until EMS arrives
When the AED advises no shock, CPR should be resumed immediately because a non-shockable rhythm still requires circulation support.
Question 2: Which of the following is a leading cause of workplace fatalities in the US construction industry, according to OSHA?
- Repetitive strain injuries
- Electrocution (Correct answer)
- Heat stroke
- Hearing loss
Correct answer: Electrocution
Electrocution is one of OSHA's Fatal Four construction hazards, responsible for a significant percentage of construction worker deaths annually.
Question 3: An employee has a deep laceration on the forearm with heavy bleeding. Direct pressure has been applied for 10 minutes and bleeding has not stopped. What is the next step?
- Remove the bandage to inspect the wound
- Apply a tourniquet 2–3 inches above the wound and note the time (Correct answer)
- Apply ice directly to the wound to constrict vessels
- Have the worker elevate their arm and rest
Correct answer: Apply a tourniquet 2–3 inches above the wound and note the time
When direct pressure fails to control life-threatening extremity bleeding, a tourniquet applied 2–3 inches above the wound is the next intervention.
Question 4: What is the recommended depth of chest compressions for adult CPR?
- 1–1.5 inches
- At least 2 inches (5 cm) (Correct answer)
- 3–4 inches
- As deep as possible regardless of depth
Correct answer: At least 2 inches (5 cm)
Current AHA guidelines recommend compressing the adult chest at least 2 inches (5 cm) but not more than 2.4 inches for effective CPR.
Question 5: A new employee notices a frayed electrical cord on a piece of equipment. What is the safest course of action?
- Wrap the frayed section with electrical tape and continue using it
- Avoid the cord and report the hazard to a supervisor immediately
- Unplug the equipment and tag it out of service (Correct answer)
- Move the cord away from foot traffic and monitor it
Correct answer: Unplug the equipment and tag it out of service
Unplugging and tagging defective equipment out of service prevents accidental use and eliminates the electrical shock or fire hazard immediately.
Question 6: Which factor most increases the risk of slips and falls in a warehouse environment?
- Proper use of safety signage
- Adequate lighting throughout aisles
- Wet or oily floor surfaces without warning signs (Correct answer)
- Clearly marked pedestrian walkways
Correct answer: Wet or oily floor surfaces without warning signs
Wet or oily floors with no warnings are a primary cause of slip-and-fall incidents; immediate cleanup and signage are required.
Question 7: When treating a worker with suspected hypothermia after prolonged outdoor cold exposure, which action should be avoided?
- Moving the worker to a warm indoor area
- Removing wet clothing gently
- Vigorously rubbing or massaging the extremities (Correct answer)
- Covering the worker with warm blankets
Correct answer: Vigorously rubbing or massaging the extremities
Vigorous rubbing can cause cold blood from the extremities to rush to the core and trigger dangerous cardiac arrhythmias in hypothermic patients.
