Part 1: Sprinkler System — Visual Checks (NFPA 25)
These items can be checked by a non-specialist. They mirror the monthly and annual visual inspection items from NFPA 25. Walk the full building and check every area where sprinkler heads are installed.
Control valves and water supply
- All control valves (OS&Y, PIV, butterfly) are in the fully open position. Stems on OS&Y valves should be extended; butterfly and PIV valves should have their locking device engaged in the open position.
- No control valve is partially closed, wedged, or blocked from view.
- Control valve location signs are posted and legible at each valve.
- Water pressure gauges read within the normal range shown on the system data plate. Gauges are not broken, cracked, or fogged.
- The fire department connection (FDC) on the exterior is visible, unobstructed, and capped. No landscaping, fences, or stored material is blocking access. Caps are present and removable.
- The FDC area is marked with a sign visible from the driveway approach.
Sprinkler heads
- No heads show signs of paint, whitewash, or any coating. (Painted heads must be replaced — paint alters the heat-response time.)
- No heads are corroded, show white mineral deposits, or have visible damage. Corroded heads must be replaced.
- All heads are correctly oriented — upright heads point up, pendent heads point down, sidewall heads are horizontal. A rotated or knocked-askew head must be reported to your contractor.
- No heads are obstructed by shelving, equipment, signs, or stored material within 18 inches below the deflector plate.
- Heads near heat sources (HVAC supply registers, skylights, equipment with heat discharge) have the correct high-temperature rating for their location. Standard heads (135–165°F) in a location that regularly exceeds 100°F ambient will activate prematurely.
- The sprinkler cabinet contains the required stock of spare heads — at least 6, or 1% of the total system count (whichever is greater) — plus a head wrench. Cabinet is visible and accessible.
Pipes and hangers
- Visible piping shows no signs of active leaking, mineral deposits, or staining that indicates a slow leak.
- Pipe hangers appear intact — no missing, bent, or disconnected hangers. Unsupported sections of pipe can shift and change head orientation.
- No piping has been cut, capped, disconnected, or modified in a way that doesn't appear on the original system drawings. Unauthorized pipe modifications are a serious violation.
- Pipe insulation (where required in cold areas) is intact with no gaps that expose pipe to temperatures below 40°F.
Alarm and monitoring
- The water-flow alarm device (bell, horn, or electric alarm) is present and unobstructed.
- If the system is connected to a monitoring company, verify the account is active. Call your monitoring company to confirm they show the system as "normal" — not in alarm, supervisory, or trouble condition.
- The system's last inspection tag is present at the riser and shows a date within the required inspection cycle.
- Any open trouble signals on the fire alarm panel related to the sprinkler system (tamper, supervisory, flow) are logged, have a known cause, and are being actively resolved.
Part 2: Kitchen Hood Suppression System (NFPA 96)
These checks apply to any restaurant, café, commissary kitchen, or food service operation with commercial cooking equipment. Walk these items before each semi-annual service visit, and check monthly as part of your kitchen safety routine.
Visual condition
- The agent storage container (tank or cartridge) is mounted securely in its bracket. It has not been moved, dropped, or physically damaged.
- The pressure gauge on the agent container is in the green zone. A gauge in the red (high or low) must be reported to your contractor immediately — do not continue using the cooking equipment until the system is serviced.
- All discharge nozzles in the hood are present, pointing in the correct direction, and free of grease buildup or blockage. A clogged nozzle will not discharge agent properly.
- Nozzle blow-off caps (where present) are intact and not damaged. These caps keep grease out of the nozzles between activations.
- The fusible link(s) on the system are intact — not melted, bent, corroded, or missing. Fusible links are replaced by your contractor at each service, but physical damage between services requires immediate attention.
- No cooking equipment has been added, moved, or replaced since the last service. Any change to the appliance layout requires re-evaluation of nozzle coverage by your contractor.
Manual pull station
- The manual pull station (often a red handle on a cable) is visible, unobstructed, and accessible without walking toward the cooking equipment.
- The pull station cable shows no kinks, breaks, or missing sections.
- All kitchen staff know where the pull station is and how to use it. (Pull stations should be included in your new employee fire safety orientation.)
Gas shutoff interlock
- The gas or electric shutoff valve that the suppression system controls is accessible and not blocked by equipment or stored material.
- The shutoff valve is not locked, zip-tied, or otherwise prevented from closing. (This is a fire-code violation and a serious life-safety issue — the interlock must be able to operate.)
- Your staff know how to manually reset the shutoff valve after a system activation or false trigger. This is a separate step from restocking the agent — the fuel cannot be restored until the system has been recharged and recertified by a licensed technician.
Hood and duct grease management
- The grease filters in the hood are cleaned on the schedule required by NFPA 96 (daily or weekly for high-volume cooking, monthly for lower-volume). Filters are not damaged, bent, or missing.
- The grease collection cup or drip pan below the filters is not overflowing. A full grease cup is a fire hazard entirely separate from the suppression system.
- The suppression system service tag on the hood shows a date within the last 6 months (or 3 months for solid-fuel cooking). Expired service means the system may no longer be in working condition.
Part 3: Clean Agent System (NFPA 2001)
For server rooms, data centers, or other spaces protected by FM-200, Novec 1230, Inergen, or similar clean agent systems.
- Agent storage cylinders are mounted securely in their racks and have not been moved or physically damaged.
- Cylinder pressure gauges (or scales, for liquid agents) show reading within the manufacturer's normal range. A cylinder that is low by more than 5% must be recharged before the space can be considered protected.
- The control panel for the system shows no trouble or alarm conditions. A steady green light (or equivalent "normal" indicator) is the expected status.
- The manual abort station (where installed) is clearly labeled and accessible. Staff should know that pressing abort during the pre-discharge warning gives them a short delay to evacuate — it does not permanently disable the system.
- The manual discharge station (separate from abort) is clearly labeled and accessible for use only as a backup in case the automatic detection fails.
- All penetrations in the protected room — cable trays, conduit entries, HVAC dampers, door frames — are sealed. An unsealed room cannot hold agent concentration long enough to suppress the fire. Even small gaps matter.
- The room doors are self-closing (spring-hinged or magnetic hold-open with fail-safe release) and close fully without gaps.
- All HVAC dampers in the room are operational and set to close automatically on system activation. Open dampers allow agent to vent immediately, preventing suppression.
- Audible and visual pre-discharge alarms (sounder, strobe) are functioning. These are the warning system for any person in the room at time of activation.
- The system's last inspection tag or certificate is present and within the required service interval (semi-annual visual, annual full inspection).
Part 4: After-Inspection Actions
When you find a deficiency on this checklist, here's how to handle it.
| Finding | Urgency | Action |
|---|---|---|
| Control valve partially or fully closed | Immediate | Open valve fully. Call your contractor to inspect and document. If you cannot verify why it was closed, treat as a potential system impairment. |
| Kitchen hood pressure gauge in red | Immediate | Do not use cooking equipment until the system is serviced and recertified. Call your contractor today. |
| Sprinkler head painted, corroded, or damaged | Within 30 days | Schedule head replacement with your contractor. Do not attempt to replace heads yourself — incorrect installation will void the system's listing. |
| Storage material within 18 inches of a sprinkler head | Before next business day | Move the material. This one you can fix yourself. It's one of the most common and most citable violations. |
| FDC blocked or capped missing | Within 7 days | Clear obstruction and order replacement caps from your contractor. File in your maintenance log. |
| Service tag expired | Within 30 days | Schedule your overdue inspection. If an inspector visits before you do, this will be a citation. |
| Clean agent cylinder low or empty | Immediate | The space is unprotected. Schedule recharge immediately and notify any monitoring company of the impairment. |
| Hood nozzle blocked with grease | Within 7 days | Call your contractor. Nozzle cleaning requires disassembly and may require agent pressure testing to confirm integrity. |
Posting and recordkeeping requirements
- NFPA 25 requires that current inspection records be available for review on-site. Keep the last two inspection reports in a binder at the riser or in the building manager's office.
- NFPA 96 requires that the current kitchen hood inspection report be posted in the kitchen or available for review by the inspector.
- For clean agent systems, the enclosure integrity test report and last annual service report should be maintained in the protected room or the equipment room.
- Any system impairment (a portion of the system taken out of service for repair) must be logged with the date, affected zone, reason, and planned restoration date. Many jurisdictions require notification to the fire department or monitoring company when a system is impaired.
