MPOETC Emergency Response Procedures 4 — Questions and Answers
Question 1: An officer responds to a reported gas leak in an apartment building. Residents are still inside. What is the MOST important immediate action?
- Search each unit for the source of the leak
- Turn off light switches to prevent sparks
- Evacuate residents and prohibit use of flames or electrical devices (Correct answer)
- Open all windows to ventilate the building
Correct answer: Evacuate residents and prohibit use of flames or electrical devices
Evacuating the building and eliminating ignition sources protects lives until the gas company can safely address the leak.
Question 2: What does 'CBRN' stand for in emergency response planning?
- Chemical, Biological, Radiological, Nuclear (Correct answer)
- Critical Building Resource Network
- Command, Barrier, Rescue, Neutralize
- Civilian, Building, Rescue, Notification
Correct answer: Chemical, Biological, Radiological, Nuclear
CBRN refers to Chemical, Biological, Radiological, and Nuclear threats, representing categories of weapons of mass destruction.
Question 3: During a flooding emergency, a vehicle is submerged with an occupant inside. If the vehicle is still sinking, what is the BEST advice to give the occupant?
- Open the door immediately
- Wait until the vehicle fills with water before opening the door
- Break the window before the vehicle sinks (Correct answer)
- Call 911 and wait for rescue
Correct answer: Break the window before the vehicle sinks
Breaking a window before the vehicle sinks allows escape before water pressure makes door-opening impossible and before panic sets in.
Question 4: When applying a tourniquet to control severe extremity bleeding, where should it be placed?
- Directly over the wound
- 2–3 inches above the wound (Correct answer)
- As close to the hand or foot as possible
- Over a joint for maximum compression
Correct answer: 2–3 inches above the wound
A tourniquet should be placed 2–3 inches proximal (above) the wound on the limb, never over a joint.
Question 5: A large crowd event becomes unruly and officers must disperse it. According to standard crowd control principles, what is the FIRST step?
- Deploy chemical agents immediately
- Issue clear, loud verbal warnings and lawful orders to disperse (Correct answer)
- Charge the crowd with batons
- Arrest the most visible agitators first
Correct answer: Issue clear, loud verbal warnings and lawful orders to disperse
Crowd control policy requires officers to give clear verbal commands and lawful dispersal orders before escalating to physical force.
Question 6: An officer arrives at a scene where a victim has an impaled object in the chest. What is the correct field treatment?
- Remove the object and apply direct pressure
- Leave the object in place and stabilize it (Correct answer)
- Push the object further in to control bleeding
- Cover with a bandage and apply pressure around the object only
Correct answer: Leave the object in place and stabilize it
Impaled objects should never be removed in the field; they should be stabilized in place to prevent further injury and blood loss.
Question 7: What is the 'warm zone' (also called the contamination reduction zone) in a hazmat incident?
- The area where the hazmat source is located
- The area between the hot zone and cold zone where decontamination occurs (Correct answer)
- The command post area
- The perimeter established for civilian bystanders
Correct answer: The area between the hot zone and cold zone where decontamination occurs
The warm zone is the transitional area between the contaminated hot zone and the clean cold zone where decontamination of personnel and equipment occurs.
