Study Notes
Safety Rules for Aerial Devices
- Maintain a minimum distance of 10 feet from overhead power lines when operating aerial devices to prevent electric shock.
- High voltages can arc significant distances; water on fireground increases conductivity, heightening risks.
- Avoid extending or retracting any aerial ladder while a person is on it to prevent crush injuries from shifting rungs.
Importance of Overhaul
- Efficient overhaul is crucial for preventing rekindling and ensuring all hidden fires are extinguished.
- A hasty or inadequate overhaul can lead to public dissatisfaction and increased fire loss.
- Historical example: In 2010, six firefighters suffered injuries due to a collapsed parapet wall after they inadequately overhauled a previous fire scene.
Understanding Overhaul
- Definition: Any action taken to expose hidden fire and ensure complete extinguishment.
- Damage may be necessary to locate hidden fire, but proper justification for openings is essential to occupy residents.
Phases of Overhaul
- Precontrol: Conducted under challenging conditions while the fire is active; focuses on stopping fire spread.
- Postcontrol: Detailed examination for remaining fire, prioritizing thoroughness over speed, with less pressure for immediate action.
Key Areas for Examination
- Examine vertical voids (e.g., shaft columns) and horizontal voids (e.g., cocklofts) for potential fire spread.
- Older building constructions often have concealed voids allowing fire movement; knowledge of building types is essential in identifying risks.
Thermal Imaging Cameras (TICs)
- TICs represent a significant advancement in firefighting, providing visual images of heat sources.
- Increasingly affordable, TICs improve efficiency in locating hidden fires and have proven life-saving in various scenarios.
Senses Utilized During Overhaul
- Sight: Visual indicators of fire (e.g., smoke, blistering paint) guide firefighters on where to investigate further.
- Hearing: Sounds of combustion (snap, crackle, pop) can direct attention to areas needing examination.
Careful Assessment Required
- Firefighters should be cautious when using touch during overhaul; injury can occur from high-temperature surfaces.
- Observe the “15-second, 2-minute rule” for temperature assessment on suspected surfaces before making openings.
Additional Precautions
- Smell is less utilized but can detect the difference between smoke and steam; SCBA should be worn to preserve this sense and protect lungs.
- Ongoing ventilation of the building is crucial to ensure a safe environment for firefighting personnel during overhaul operations.
