MTA Emergency Response 4 — Questions and Answers
Question 1: During a transit emergency, the Incident Command System (ICS) designates one officer as the 'Incident Commander.' What is that person's PRIMARY role?
- Conduct all field arrests personally
- Oversee all aspects of the incident response and coordinate resources (Correct answer)
- Document every action taken by responding officers
- Serve as the sole liaison to the media
Correct answer: Oversee all aspects of the incident response and coordinate resources
The Incident Commander has overall authority and responsibility for managing the incident, including coordinating personnel and resources.
Question 2: A passenger reports smelling gas near a station utility room. The officer confirms a faint gas odor. What should the officer do IMMEDIATELY?
- Search the utility room using a flashlight
- Switch off any nearby electrical panels
- Evacuate the area and prohibit ignition sources (Correct answer)
- Ventilate the room by propping the door open and waiting inside
Correct answer: Evacuate the area and prohibit ignition sources
Gas leaks require immediate evacuation and elimination of all ignition sources; switches and electrical equipment can spark and ignite accumulated gas.
Question 3: A transit officer is performing CPR on a victim when an AED becomes available. After attaching the AED and it advises 'No Shock Recommended,' the officer should:
- Discontinue CPR since the AED detected no shockable rhythm
- Immediately resume CPR and continue until EMS arrives (Correct answer)
- Check the AED pads and reattach them before retrying
- Administer a manual shock using the AED override function
Correct answer: Immediately resume CPR and continue until EMS arrives
A 'No Shock Recommended' message means the rhythm is not shockable, but CPR must continue because the heart may not be beating effectively.
Question 4: While patrolling a transit station, an officer observes white powder spilled near an air vent. A nearby passenger is coughing. What should the officer do FIRST?
- Collect a sample of the powder for laboratory analysis
- Evacuate the immediate area and avoid contact with the powder (Correct answer)
- Fan the powder away from the vent with a jacket
- Wet a cloth and clean up the powder to prevent further spread
Correct answer: Evacuate the immediate area and avoid contact with the powder
Unknown white powder near a ventilation source should be treated as a potential biological or chemical agent; evacuation and hazmat notification are the first steps.
Question 5: Under the National Incident Management System (NIMS), the recommended span of control for a supervisor during an emergency is:
- 1 to 3 subordinates
- 3 to 7 subordinates (Correct answer)
- 8 to 12 subordinates
- As many as needed to resolve the incident quickly
Correct answer: 3 to 7 subordinates
NIMS recommends a span of control between 3 and 7 subordinates, with 5 considered optimal, to maintain effective supervision during emergencies.
Question 6: An officer is rendering first aid to a passenger with severe bleeding from an arm wound. Which technique should be applied FIRST?
- Apply a tourniquet above the wound immediately
- Elevate the arm and apply direct pressure to the wound (Correct answer)
- Pour water over the wound to clean it before applying pressure
- Apply an ice pack to constrict blood vessels
Correct answer: Elevate the arm and apply direct pressure to the wound
Direct pressure and elevation are the first-line methods to control external bleeding before considering tourniquet application.
Question 7: A transit officer responds to a report of a person experiencing a heart attack on a platform. The passenger is conscious and complaining of chest pain. Which action is MOST appropriate?
- Have the passenger walk briskly to keep blood circulating
- Have the passenger sit or lie down, loosen clothing, and call EMS (Correct answer)
- Administer water and instruct the passenger to take deep breaths
- Request the passenger's medical history before calling EMS
Correct answer: Have the passenger sit or lie down, loosen clothing, and call EMS
Keeping the patient calm, seated or lying down, and immediately calling EMS reduces cardiac workload and ensures rapid professional medical response.
