Study Notes
Sizing Up Sprinklered Buildings
- Assess auxiliary fire-suppression systems like sprinklers, standpipes, and foam systems during size-up.
- Verify the presence of these systems; building codes often mandate standpipes in high-rises and foam systems in specific areas.
- Automatic sprinkler systems are less predictable; many large buildings may lack them while smaller ones could be fully protected.
- Signs of a sprinkler system include siamese connections, water motor alarm gongs, and water discharge from pipes.
- Prefire inspections provide vital information about the sprinkler system’s location and operational status.
Response to Sprinkler Alarms
- Upon arrival, establish if the sprinkler system is operational; building personnel can assist with information.
- A significant percentage of sprinkler alarms indicate minor issues rather than actual fires, leading to minimal initial responses.
- Serious fires in sprinklered buildings often have systems that might be out of service (OOS).
- Malware activity might result in an arsonist turning off sprinklers, complicating firefighting efforts.
- Treat fires in OOS sprinklered buildings with the same caution as non-sprinklered buildings, as both can be equally difficult to control.
Operating Sprinkler Systems
- Multiple riser systems require attention to fire department connections (FDC) below main control valves.
- If the OS&Y valve is closed, water cannot be pumped into the system or zone.
- Maintain a strategy to engage sprinklers quickly during an incident to aid in fire suppression.
- Monitor the effects of sprinkler discharge following activation and notify interior units of water flows.
Investigating False Alarms
- Decide whether to forcibly enter a structure during a false alarm or await the owner's arrival.
- Consider prefire planning knowledge about sprinkler systems; pressures may stabilize after a false alarm.
- Signs to confirm presence or absence of fire include water flow or alarms from the system.
Locating and Operating Control Valves
- Familiarize with the OS&Y valve, located at the sprinkler riser; indicates the valve's position by the stem's protrusion.
- Several types of control valves (PIV and WIV) can indicate whether the system is open or closed.
- Locating control valves early is crucial, especially due to modern hydraulic designs complicating the identification of systems.
Restoration of Sprinkler Protection
- Firefighters typically drain water from systems post-fire to prevent flooding and assist in salvage operations.
- Restoration of the sprinkler system may vary by department policy, with some opting for minimal intervention.
- A temporary measure may involve replacing fused sprinkler heads using spare heads and tools available on-site.
- Notify building owners in writing about any damage incurred from forced entry or repair actions.
Key Considerations
- Sprinkler systems generally offer considerable protection but require ongoing operational status to be effective.
- Awareness of building layout and system design enables better management of fire incidents involving sprinkler systems.
- Always ensure restoration of protection and functionality in sprinklered buildings after an incident to facilitate ongoing safety.
