OFA Emergency Response & Scene Assessment 2 — Questions and Answers
Question 1: When approaching an industrial accident scene with chemical spills, what is your FIRST priority?
- Call 911 immediately
- Identify the chemical using SDS sheets
- Ensure the scene is safe for rescuers (Correct answer)
- Begin triage on injured workers
Correct answer: Ensure the scene is safe for rescuers
Rescuer safety is always the first priority; entering an unsafe chemical scene can create additional casualties.
Question 2: A worker is unresponsive after a fall from height. What should you assess FIRST?
- Breathing and circulation
- Pupil response
- Level of consciousness (Correct answer)
- Spinal alignment
Correct answer: Level of consciousness
Level of consciousness (LOC) is the first step in primary assessment using the AVPU scale (Alert, Voice, Pain, Unresponsive).
Question 3: Which of the following best describes the purpose of a primary survey in emergency response?
- Gather a complete medical history
- Identify and treat life-threatening conditions immediately (Correct answer)
- Document all injuries for legal purposes
- Determine the mechanism of injury
Correct answer: Identify and treat life-threatening conditions immediately
The primary survey (DRABC) rapidly identifies and manages life-threatening conditions such as airway obstruction, absent breathing, and severe bleeding.
Question 4: You arrive at a scene where a co-worker has been electrocuted and is still in contact with the power source. What do you do?
- Pull the victim away using your bare hands quickly
- Use a dry wooden stick to push the victim free
- Do not approach until the power is confirmed off (Correct answer)
- Begin CPR immediately from a distance
Correct answer: Do not approach until the power is confirmed off
Electrical current can arc and kill a rescuer; never approach until a qualified person has confirmed power is disconnected.
Question 5: The acronym SAMPLE, used during secondary assessment, stands for Signs/Symptoms, Allergies, Medications, Pertinent history, Last oral intake, and:
- Level of consciousness
- Events leading to the emergency (Correct answer)
- Location of pain
- Skin color and temperature
Correct answer: Events leading to the emergency
The 'E' in SAMPLE stands for Events leading to the emergency, helping to understand what precipitated the patient's condition.
Question 6: When managing multiple casualties at a workplace incident, which triage tag color indicates a patient who is deceased or has unsurvivable injuries?
- Red
- Yellow
- Green
- Black (Correct answer)
Correct answer: Black
Black triage tags are assigned to deceased victims or those with injuries so severe that survival is unlikely even with immediate care.
Question 7: A scene size-up at a construction site should include an assessment of all of the following EXCEPT:
- Number of patients
- Mechanism of injury
- Need for additional resources
- Patient's insurance information (Correct answer)
Correct answer: Patient's insurance information
Scene size-up focuses on safety, number of victims, mechanism of injury, and resource needs — not administrative or insurance details.
