OIT Emergency Response and First Aid 3 — Questions and Answers
Question 1: What is the correct treatment for a second-degree thermal burn covering the forearm of an operator?
- Apply butter or oil to soothe the burn
- Cool with cool (not ice) water for 10-20 minutes (Correct answer)
- Pop any blisters to prevent infection
- Wrap tightly with non-breathable tape
Correct answer: Cool with cool (not ice) water for 10-20 minutes
Cool running water for 10–20 minutes reduces tissue damage; ice, butter, and popping blisters worsen outcomes.
Question 2: An operator is found unconscious in a confined space with suspected toxic atmosphere. The first responder should:
- Enter immediately to pull the victim out
- Don appropriate respiratory protection before entering (Correct answer)
- Call out to the victim to assess responsiveness
- Ventilate the space with a fan before entering without PPE
Correct answer: Don appropriate respiratory protection before entering
Entering a toxic atmosphere without proper respiratory protection risks creating additional casualties.
Question 3: During a facility emergency, the Emergency Assembly Point (EAP) is primarily used to:
- Store emergency equipment
- Account for all personnel after evacuation (Correct answer)
- Coordinate fire suppression activities
- Stage incoming emergency responders
Correct answer: Account for all personnel after evacuation
The EAP allows supervisors to conduct headcounts and ensure all personnel are safely evacuated.
Question 4: A worker inhales chlorine gas and is coughing severely. After removing them from exposure, what is the next priority?
- Have them drink large amounts of water
- Monitor breathing and administer oxygen if available (Correct answer)
- Induce vomiting to clear the toxin
- Apply a chemical neutralizer to the face
Correct answer: Monitor breathing and administer oxygen if available
Respiratory support and oxygen administration address the primary hazard of chlorine inhalation — impaired breathing.
Question 5: Which NFPA diamond section indicates health hazard rating for a chemical?
- Red (top)
- Blue (left) (Correct answer)
- Yellow (right)
- White (bottom)
Correct answer: Blue (left)
The blue section on the left of the NFPA 704 diamond indicates the health hazard rating on a scale of 0–4.
Question 6: A coworker's clothing catches fire. What is the correct response sequence?
- Run to get a fire extinguisher first
- Stop, drop, and roll — then cool burns with water (Correct answer)
- Remove burning clothing immediately regardless of injury
- Douse with any available liquid including solvents
Correct answer: Stop, drop, and roll — then cool burns with water
Stop, drop, and roll extinguishes flames; cooling with water then addresses burns — solvents are never appropriate.
Question 7: What does the term 'universal precautions' mean in workplace first aid?
- Using the most powerful PPE available for every task
- Treating all blood and body fluids as potentially infectious (Correct answer)
- Calling 911 before beginning any first aid
- Only trained medical personnel may provide first aid
Correct answer: Treating all blood and body fluids as potentially infectious
Universal precautions means assuming all blood and body fluids are infectious to protect the first aider from bloodborne pathogens.
