CPS Firefighter Test Oral Information Comprehension Questions and Answers 1 — Questions and Answers
Question 1: Read the following radio transmission and answer the question that follows. 'Dispatch to all units responding to the structure fire at 1550 North Oak Street. Be advised, the reporting party states this is a vacant building, but neighbors have reported squatters may be inside. The fire is on the second floor of a two-story, wood-frame residence. A responding battalion chief reports a large column of black smoke is visible from five blocks away. Police are on scene and are attempting to control traffic.' Based on this transmission, which piece of information should raise the most immediate concern for the operational strategy of the first arriving fire crew?
- The presence of police on scene controlling traffic.
- The fire is located on the second floor.
- The building is a two-story, wood-frame residence.
- The possibility of squatters inside the vacant building. (Correct answer)
Correct answer: The possibility of squatters inside the vacant building.
The primary mission of the fire service is life safety. While all the information is important, the report of possible squatters elevates the incident from a simple structure fire in a vacant building to a potential rescue situation, which dictates a more aggressive interior search and rescue strategy.
Question 2: Read the following instructions from a Captain and answer the question below. 'Alright team, here's the plan. Engine 5, you'll be our water supply; lay a 5-inch line from the hydrant on the corner to Engine 1. Engine 1, you're the attack pumper. I need a 1.75-inch crosslay pulled to the front door for fire attack. Truck 1, you're assigned ventilation. I want a vertical vent over the main body of the fire as soon as the attack line is in place and flowing water. All crews, maintain radio discipline.' According to the Captain's orders, what action must be completed before Truck 1 begins its primary assignment?
- Engine 5 has established a water supply.
- The attack line from Engine 1 is inside the structure and actively flowing water. (Correct answer)
- All crews have confirmed the orders over the radio.
- Police have secured the perimeter of the scene.
Correct answer: The attack line from Engine 1 is inside the structure and actively flowing water.
The Captain explicitly states that Truck 1 should perform vertical ventilation 'as soon as the attack line is in place and flowing water.' This is a critical safety step to ensure that ventilation is coordinated with fire suppression to prevent creating a more dangerous fire environment for the interior crew.
Question 3: Read the following paragraph from a training manual and answer the question. 'When responding to an emergency involving downed power lines, extreme caution is paramount. Responders must treat all downed lines as energized and dangerous. A safety perimeter, often called a 'hot zone,' should be established at a distance equal to at least one full span between utility poles. No personnel or equipment should enter this zone. The primary role of the fire department is to secure the area and deny entry until the utility company can confirm the lines have been de-energized.' Based on the passage, what is the fire department's main responsibility at an incident with downed power lines?
- Attempting to move the power lines using specialized tools.
- Spraying water on the lines to cool them down.
- Isolating the area and preventing entry until the utility company arrives. (Correct answer)
- Immediately evacuating all buildings within one block of the incident.
Correct answer: Isolating the area and preventing entry until the utility company arrives.
The passage clearly states that the fire department's primary role is to secure the area and deny entry. This involves establishing a hot zone and waiting for the utility company, which has the proper training and equipment to handle the hazard safely.
Question 4: Read the following scenario description and answer the question. 'Upon arrival at a vehicle extrication, the Incident Commander gives the following order: 'Before we use the hydraulic spreader, the vehicle must be stabilized. I need a crew to place step chocks under the A-frame on the driver's side and use a rescue strut to support the C-pillar on the passenger side. Do not begin any cutting or spreading operations until stabilization is confirmed complete.'' What is the purpose of the actions ordered by the Incident Commander?
- To lift the vehicle off the ground to provide better access.
- To prevent the vehicle from shifting or moving during the extrication process. (Correct answer)
- To disconnect the vehicle's battery before using rescue tools.
- To create an opening for the hydraulic spreader.
Correct answer: To prevent the vehicle from shifting or moving during the extrication process.
Placing chocks and support struts are methods of vehicle stabilization. The commander's order to perform these actions before using powerful hydraulic tools is to ensure the vehicle remains stable, protecting both the victim and the rescuers from injury caused by unexpected movement.
Question 5: Read the following passage about fire extinguisher types. 'Class K fire extinguishers are specifically designed for fires involving commercial deep fryers that use combustible cooking media like vegetable or animal oils. They utilize a wet chemical agent that, when applied to the burning oil, creates a soapy foam blanket through a process called saponification. This blanket both cools the oil and smothers the fire by cutting off the oxygen supply. Using a Class A or B extinguisher on these fires can be ineffective and may even cause the burning grease to splash, spreading the fire.' According to the passage, how does a Class K extinguisher put out a grease fire?
- By displacing oxygen with a cloud of carbon dioxide gas.
- By creating a chemical reaction that forms a fire-suppressing foam blanket. (Correct answer)
- By rapidly cooling the entire appliance with a large volume of water.
- By interrupting the fire's chemical chain reaction with a dry powder.
Correct answer: By creating a chemical reaction that forms a fire-suppressing foam blanket.
The passage explicitly describes the process of saponification, where the wet chemical agent reacts with the burning oil to create a 'soapy foam blanket.' This blanket is the mechanism that smothers and cools the fire.
Question 6: Read the following statement from an officer. 'The search team reported that the structural integrity of the floor in the fire room is compromised. They described the floor as feeling 'spongy' underfoot, and they could hear audible creaking with any movement. Due to this report, I have pulled all crews out of that area and am switching our strategy from an offensive to a defensive attack.' What does the officer's statement imply?
- The fire is now under control and crews can exit.
- The officer needs more firefighters to enter the building.
- The risk of a structural collapse is too high for firefighters to operate inside. (Correct answer)
- The water supply for the firefighting operation has been lost.
Correct answer: The risk of a structural collapse is too high for firefighters to operate inside.
A 'spongy' floor and audible creaking are classic signs of failing structural components due to fire damage. The officer's decision to pull crews out and switch to a defensive (exterior) attack indicates that the risk of collapse has become unacceptable, making it too dangerous for interior operations.
