Study Notes
Commercial Occupancies
- High-rise buildings often have electrical rooms located on each floor.
- Isolating electrical issues to a single floor is crucial to maintain power to the entire building.
- Commercial properties may include UPS rooms that provide over 500 volts of DC for temporary power, posing acid release hazards from batteries.
Residential Occupancies
- Immediate disconnection of electricity during residential fires is important for safety.
- Firefighters must not engage in operations if energized circuits create life safety risks.
- Ground ladders should be handled with caution, avoiding electrical service areas and overhead wires.
- Signs of electrical issues include flickering lights and appliances giving shocks; the presence of strong electrical odors may indicate overheating equipment.
- Thermal Imaging Cameras (TICs) can identify hidden fires and overheating wires.
Response to Downed Lines
- Locating downed lines is highly dangerous and can lead to fatalities.
- Identify electrical entry points from a safe distance and locate both ends of the downed wire.
- Establish a "Danger Zone," extending at least the distance of one wire span beyond the damage.
- Persons in energized vehicles should remain inside until the electrical energy is eliminated.
- In cases where imminent risks are present, occupants may need to jump clear of the vehicle.
- Fires near utility poles should be left alone to avoid hazards related to overhead wires.
Night-Time and Limited Visibility Situations
- Advise residents of potential downed lines during low visibility or snow, cordoning off affected areas with caution tape.
- Remain on scene to monitor arcing from downed lines but return to service if no further hazards are present.
- Notify homeowners of arcing situations, ensuring they stay clear.
Notification of the Assistant Chief
- Certain conditions require alerting the Assistant Chief for expedited responses from PSO:
- Prolonged waiting for PSO assistance beyond one hour.
- When individuals are in contact with energized lines.
- Stalled operations due to electrical hazards.
- Vehicle incidents involving energized lines with occupants inside.
- Lines down on busy streets affecting traffic.
- The IC should relay status updates to the Assistant Chief over Subfleet communication.
High Call Volume Management
- During increased call volumes, prioritize emergency responses and allocate resources effectively.
- Precautions must be taken before leaving the scene of an electrical emergency, including notifying homeowners and securing the area with caution tape.
Substation and Underground Vault Response
- Firefighting at electric generating stations, substations, or vaults waits for utility agency representatives.
- Avoid directing water into manholes or underground electrical fires until approved by authorized personnel.
- Once de-energized, electrical equipment fires are treated as conventional Class A or B fuel fires.
