These apply to Type I hoods (grease-producing appliances) and associated fire suppression systems (e.g., UL 300-compliant). Safety Precautions Turn off all power to the ventilation system (fans, blowers, and cooking appliances) to prevent electrical hazards, per NFPA 96 11.4. Ensure proper ventilation in the kitchen to avoid inhaling cleaning fumes or grease residues. Use exhaust fans or open windows if safe. Wear protective gloves and eyewear when handling degreasers or cleaning agents. Clean Fan Blades, Motors, and Components Remove fan covers and access panels (as per Mechanical Code Chapter 5) to reach fan blades, motors, and ducts. Use an FDNY-approved degreaser or a solution of warm water and dish soap to remove grease and dirt buildup. Grease accumulation exceeding 1/8 inch requires immediate cleaning per NYC FC §609.5.3. Scrub components thoroughly with a non-abrasive brush and rinse with clean water. Ensure no water enters electrical components. Inspect and Lubricate Bearings and Motors Check fan bearings and motors for wear, corrosion, or damage. Excessive wear (e.g., grinding noises) may require replacement. Lubricate bearings according to manufacturer specifications (e.g., use food-safe lubricants for kitchen environments). Refer to the equipment manual for guidance. Replace worn bearings or motors with manufacturer-approved parts to maintain warranty and compliance. Check Electrical Connections Inspect wiring, switches, and connections for fans and blowers. Look for loose, frayed, or damaged wires, which can cause malfunctions or fire hazards. Secure all connections and replace damaged components with UL-listed parts, per NFPA 96 9.2. Ensure fire suppression system integration (e.g., auto-shutoff for gas/electric) is functional, as required by NYC FC §904.11. Test the System Restore power and test fans and blowers for smooth operation. Listen for unusual noises (e.g., rattling, grinding) or vibrations. Verify airflow meets design specifications (check CFM ratings in the system’s documentation). Confirm fire suppression system activation (e.g., Ansul system) during tests, as required semi-annually by NYC FC §904.5. Schedule Professional Assistance If issues persist (e.g., poor airflow, electrical faults, or suppression system failures), contact an FDNY-certified technician with W-64/P-64 Certificates of Fitness. Complex repairs, such as duct replacement or fire suppression recalibration, require professionals like Master Fire Prevention to ensure compliance. Maintain cleaning logs and tags onsite for FDNY inspections to avoid fines up to $10,000 per violation. Note: Regular maintenance (weekly for filters, quarterly for high-volume systems) prevents grease fires and ensures compliance. See our compliance timeline for detailed schedules.
