Study Notes
Dumpster/Compactor Fires
- Class A foam is recommended for extinguishing tightly-packed materials in dumpsters.
- Use appropriate size lines; booster lines are usually sufficient for standard dumpsters, while larger lines may be necessary for construction dumpsters.
- Avoid leaning over the edge of dumpsters; once a dumpster fire is controlled, it should not be approached further to prevent exposure to toxic fumes.
- Many larger dumpsters have side doors that can be utilized for better access to extinguish fires.
- Consider relocating dumpsters away from structures and vehicles, potentially requiring vehicle assistance to pull larger dumpsters.
Compactors
- Most compactors are standalone units that either compact or balk material into a detachable container, often located in fire-rated service areas.
- Compactor fires can be labor-intensive, with detached containers resembling a large dumpster.
- If a fire spreads into the compactor mechanism, it is crucial to lock out the energy source before addressing combustibles.
- Some rarer compactors come with trash chutes, which pose significant hazards to buildings and occupants; internal exposures must be assessed, particularly if fires are linked to blocked chutes.
- Modern compactors typically include fire detection and suppression systems.
Response to Areas Without Hydrants
- When relay pumping is necessary, employ the "Constant Pressure Method" (150 psi and 1000 ft of 5" hose per engine) as per the IFSTA Pumping Apparatus Driver/Operator handbook.
Water Tender Operations
- Water tender operations can involve tankers with or without pumps.
Tankers with Pumps
- Tankers equipped with pumps can supply water using a 3" line, compatible with TFD's 2½" National Standard Threads.
- It is advised to use two engines: one to pump fire streams and the second to receive water from the tanker. This ensures at least 1000 gallons are available for sustained operations.
- The forward engine pumps streams while the second engine maintains a full tank for reserve capacity during tanker swaps.
Tenders Without Pumps
- Tenders that lack pumps must unload their water into portable tanks; an engine must then draft from these tanks.
- TFD engines do not carry hard suction hoses and will rely on either a mutual aid engine drafting from a portable tank or allowing a mutual aid engine to directly supply water from their portable tank.
