Study Notes
- Fire fighters should check fire pumps manually instead of relying on remote annunciator panels.
- Systematic checks of the entire building should be conducted to verify that nothing is amiss.
- Two 2½-in. or two 3-in. hose lines should be connected to the fire department connection (FDC) for adequate water supply.
- Large buildings or complexes may have several FDCs supplying different sprinkler or standpipe systems.
- Pre-incident plans must address the location and flow of offsite water sources.
- The fire department should have access to plans for new structures and provide input regarding the best location for FDCs, fire hydrants, and other fire protection equipment.
- When there are signs of a fire and/or the sprinkler system is operating, the main objective is to support the system while ensuring that occupants are safe.
- When there is a confirmed working fire, an engine company must supply water by pumping into the FDCs, and the pump operator is required to remain at the apparatus.
- Large-diameter hose provides large quantities of water and greatly reduces friction loss, but it has potential problems to address.
- Large-diameter hose is typically tested to 200 psi, which is adequate for most sprinkler operations, but higher pressures may be required for standpipe operations.
- Department training should include potential difficulties in connecting to the FDC.
- Sprinkler systems should be shut down only after the fire is under control.
- Hose lines should be strategically positioned for an offensive attack and overhaul.
- Proper ventilation can limit fire spread and channel the fire.
- Property conservation tasks should be accomplished while extinguishment is in progress.
- The sprinkler system should be placed back in service by replacing fused sprinklers and reopening valves.
- Preincident planning is key to a successful operation at properties protected by a deluge system.
- Checking the control valve and fire pump is important.
- Deluge systems often trip interlocking devices when activated.
- It is better to shut down the deluge system too late than too early.
