After the fire is under control

Which of the following actions should be taken immediately when MAYDAY is broadcast? (469) [4.2.4, 4.3.5] All radio traffic ceases and only traffic relating to the MAYDAY is allowed. Personnel near the downed firefighter should proceed to assist with rescue. All assigned units are directed to assist with searching for the firefighter who has broadcast the MAYDAY. The MAYDAY crew is dispatched to locate the downed firefighter.

All radio traffic ceases and only traffic relating to the MAYDAY is allowed.

Cradle-in-arms lift/carry

Why must locating and isolating the fire be a priority before any search? (454) [4.3.9] Entering to search provides a ventilation opening to the structure, which could cause fire to spread. Smoke from the fire makes performing searches more difficult. Primary search cannot be performed until after the fire has been controlled. Property protection is a higher incident priority than life safety.

Entering to search provides a ventilation opening to the structure, which could cause fire to spread.

Hospital

Which is an accurate statement about using an air-monitoring device? (441) [4.3.21] If devices are used incorrectly, the safety of everyone around can be in jeopardy. Air-monitoring devices must be used under the supervision of a company officer. Air-monitoring devices can only measure one type of gas, so multiple varieties are needed at each incident. Only one type of air-monitoring device should be used at an incident.

If devices are used incorrectly, the safety of everyone around can be in jeopardy.

Why is breaching interior walls not a preferred method of escape? (472) [4.2.4, 4.3.5, 4.3.9] It could cause possible harm to victims sheltering in the next room. It requires strength, depletes air supply, and creates an additional flow path. It requires specialized tools and requires responders to remove SCBA. It inflicts too much damage on the structure.

It requires strength, depletes air supply, and creates an additional flow path.

Which of the following is one of the three principles of air management? (437) [4.3.5, 4.3.9] Turn your SCBA off once you have found an area of safe haven. Always use short, quick breaths. Always use short, quick breaths. Know your point of no return.

Know your point of no return.

Known locations of victims or occupants

How can you help rescuers find you if you are forced to shelter in place? (439) [4.3.9] Leave all doors open and marked to indicate your location Shine a light through available windows to draw attention to your location Do not go far from your assigned area Remain in the fire compartment

Shine a light through available windows to draw attention to your location

Why should personnel search behind doors and on the floor below windows? (460) [4.3.9] These places must be marked in the primary search. Smoke may overcome occupants while they are trying to escape. Visibility and air quality are best in these places. Occupants are most likely to find shelter in these places.

Smoke may overcome occupants while they are trying to escape.

How does staying low to the floor improve survivability? (470) [4.2.4, 4.3.5] It removes toxins such as carbon monoxide (CO) It allows you to exit a structure more quickly This places a battier between you and the fire, allowing you more time to find an egress point Temperatures are cooler and air may be less contaminated

Temperatures are cooler and air may be less contaminated

Why should firefighters exit the IDLH before their low-pressure alarm activates? (436) [4.3.5, 4.3.9] The remaining air is insufficient to exit even if no emergencies occur. The remaining air is an average, not specific to each firefighter, so it may be insufficient to exit from both short and long distances. The remaining air is insufficient to exit from deep inside a large structure and does not take into account emergencies that may be encountered. Hearing the alarm may cause panic, which will speed up air consumption.

The remaining air is insufficient to exit from deep inside a large structure and does not take into account emergencies that may be encountered.

What types of tools and equipment do search and rescue personnel carry? (452) [4.3.9] Thermal imagers and forcible entry tools pH meters and fluoride test paper Power saws and hydraulic tools Hydraulic rescue equipment

A primary search is: (456) [4.3.9] a slow, thorough search conducted after the fire is under control. performed by one person. a fast, thorough search performed either before or during fire suppression operations. not the time to rescue victims.

a fast, thorough search performed either before or during fire suppression operations.

A "MAYDAY" is called when: (467) [4.2.4, 4.3.5] there is a partial roof collapse. hazardous materials are found in a structure. a firefighter is in immediate danger. unconscious victims are located.

a firefighter is in immediate danger.

The AHJ should establish action levels that describe how firefighters should respond to high- or low-level alarms while performing: (448) [4.3.21] MAYDAY training. forcible entry. ventilation. air monitoring.

air monitoring.

When you are seeking to escape and you locate a window, you should: (472) [4.2.4, 4.3.5] break the window glass using heavy furniture in the room. use an escape rope to descend from the window. ask Command if opening the window will make interior conditions worse. break the glass and lower yourself to the ground head first.

ask Command if opening the window will make interior conditions worse.

You should leave the hazard zone: (438) [4.2.4, 4.3.5] once all victims have been rescued. if a PASS alarm is activated. when you reach 50% air consumption. at the same time as your team.

at the same time as your team.

If a fire is encountered in a room during search and rescue operations, rescuers should: (454) [4.3.9] close the door and report the conditions. abandon the search and immediately leave the building. leave the door open to provide ventilation to the compartment. mark the door with USAR-approved symbols.

close the door and report the conditions.

If you think your life is in immediate danger, transmit the MAYDAY signal and then: (468) [4.2.4, 4.3.5] activate your PASS device before communicating your situation to the IC. communicate your situation to the IC before activating your PASS device. call the rapid intervention crew. provide personnel accountability report.

communicate your situation to the IC before activating your PASS device.

heat levels and duration of the interior operations stay within acceptable limits for the PPE and SCBA provided.

One limitation of thermal imagers is that: (453) [4.3.9] they may not be able to help improve visibility in an obscured environment. if a structure is carpeted, they may not be able to detect fire on the floors below. they have a fairly long instrument response time. there are no fixed standards for interpretation of data.

if a structure is carpeted, they may not be able to detect fire on the floors below.

An advantage of using thermal imagers during search and rescue operations is: (452) [4.3.9] the ability to detect fires through carpeted floors. improved visibility in an obscured environment. detection of people under or behind furniture and on the opposite side of walls. the ability to see through water, glass, and other reflective surfaces.

Under normal conditions, air management increases your work time, but if you are lost or trapped, it: (434) [4.3.5, 4.3.9] will decrease your survivable time before rescue and increase your energy output. increases the amount of time you can survive before escaping or being rescued. will not be effective, because adrenaline and stress will drastically increase your consumption rate. decreases the amount of time you can survive before escaping or being rescued.

increases the amount of time you can survive before escaping or being rescued.

In order to conduct an effective search operation, firefighters must know the: (450) [4.3.9] location of the nearest water supply. layout or floor plan of the building. time the next apparatus will respond. age of the building.

layout or floor plan of the building.

If you are near the downed firefighter when a MAYDAY transmission is made: (469) [4.2.4, 4.3.5] immediately rush to assist with the rescue. immediately ventilate the area. listen closely for your orders after the transmission and do not freelance. exit the area immediately.

To be physically and mentally prepared for survival during search and rescue operations, you should: (434) [4.3.5, 4.3.9] allow the IC to look out for your crew members' safety. practice emergency exit techniques. push yourself past your limits. follow orders without question.

practice emergency exit techniques.

An advantage of marking with latch straps is that they: (454) [4.3.9] keep the door closed. are more fire resistant than other types of markers. are more visible than other types of markers. prevent the door from closing.

prevent the door from closing.

When any evacuation signal is given, all exiting crews must: (469) [4.2.4, 4.3.5] ensure that all victims have been evacuated before leaving the structure. confirm the evacuation order with the IC before exiting the structure. proceed to a designated safe area outside the collapse zone. activate their personal alert safety system (PASS) devices.
