First Aid Workplace Safety 4 — Questions and Answers
Question 1: A worker is found with a piece of metal impaled in the abdomen. What is the correct first aid approach?
- Remove the object quickly to reduce internal bleeding
- Apply pressure directly on the object to stop bleeding
- Stabilize the object in place and do not remove it (Correct answer)
- Push the object deeper to reduce air leakage
Correct answer: Stabilize the object in place and do not remove it
Impaled objects should be stabilized in place because removal can cause increased bleeding and organ damage.
Question 2: Which condition can result from prolonged exposure to noise levels above 85 dB in the workplace?
- Tinnitus and permanent hearing loss (Correct answer)
- Vertigo and loss of balance only
- Temporary color blindness
- Increased blood pressure only
Correct answer: Tinnitus and permanent hearing loss
Sustained noise above 85 dB damages hair cells in the cochlea, causing tinnitus and permanent noise-induced hearing loss.
Question 3: An employee is found unconscious near a gas leak. What should the first responder do first?
- Enter immediately and begin CPR
- Ensure the scene is safe before approaching the victim (Correct answer)
- Ventilate the area by opening windows, then enter
- Call the victim's name loudly from the entrance
Correct answer: Ensure the scene is safe before approaching the victim
Scene safety is the first priority; entering an environment with an active gas leak can incapacitate or kill rescuers.
Question 4: What is the correct technique for lifting a heavy object to prevent back injury?
- Bend at the waist, keep legs straight, and pull upward
- Keep the load far from the body for better leverage
- Bend the knees, keep the back straight, and lift with the legs (Correct answer)
- Twist the torso to redirect the load while lifting
Correct answer: Bend the knees, keep the back straight, and lift with the legs
Bending the knees and lifting with the legs keeps the spine neutral and transfers the load to stronger leg muscles.
Question 5: A coworker is experiencing chest pain radiating to the left arm and jaw. After calling 911, what should you do?
- Give the worker two acetaminophen tablets
- Have them lie flat on their back with legs elevated
- Help them sit or lie in a comfortable position and give aspirin if not allergic and not contraindicated (Correct answer)
- Encourage them to walk slowly to the medical room
Correct answer: Help them sit or lie in a comfortable position and give aspirin if not allergic and not contraindicated
Keeping the patient comfortable and giving aspirin (if appropriate) can reduce clot formation while awaiting EMS for a suspected heart attack.
Question 6: Which type of respirator protects against both particles and organic vapors?
- N95 filtering facepiece respirator
- Surgical mask
- Combination cartridge respirator with OV/P100 (Correct answer)
- Powered air-purifying respirator (PAPR) with HEPA only
Correct answer: Combination cartridge respirator with OV/P100
A combination cartridge respirator with organic vapor (OV) and P100 particulate filters protects against both chemical vapors and fine particles.
Question 7: What should a worker do if their clothing catches fire?
- Run to the nearest fire extinguisher
- Fan the flames to cool them quickly
- Stop, drop, and roll to smother the flames (Correct answer)
- Remove all clothing as quickly as possible
Correct answer: Stop, drop, and roll to smother the flames
Stop, drop, and roll smothers flames by cutting off oxygen and prevents the person from fanning the fire by running.
