How Sprinkler and Fire Suppression Systems Safeguard NYC Commercial Kitchens

5 Hidden Issues Even Top Suppression Technicians Miss That Can Lead to FDNY Range Hood Fire Safety System Failures

Maintaining a properly functioning range hood fire safety system is essential for NYC restaurants to pass FDNY inspections and avoid dangerous fire disasters. While most suppression technicians are skilled at identifying common issues, some hidden problems can still go unnoticed, resulting in inspection failures or fire risks. Here are five frequently overlooked problems:

1. Blocked or Inadequate Ductwork

Over time, grease and debris can accumulate in ductwork, even with regular cleaning. If technicians don’t thoroughly inspect hard-to-reach areas, these blockages can restrict airflow, compromise system performance, and fail to meet FDNY standards. This issue can also increase the risk of a fire spreading through the ventilation system.

2. Improper Nozzle Placement

Range hood fire suppression systems rely on nozzles to distribute extinguishing agents effectively. However, incorrect nozzle placement—such as being misaligned or too far from critical cooking equipment—can lead to incomplete suppression in the event of a fire. A technician might not notice subtle misplacements without careful attention to detail.

3. Worn or Expired Suppression Agent

Many technicians focus on the functionality of the system but overlook the condition of the suppression agent itself. Over time, suppression chemicals can degrade or expire, reducing their effectiveness. A thorough inspection should include verifying the age and condition of these agents to ensure compliance with FDNY requirements.

4. Unnoticed Electrical or Gas Line Hazards
Fire suppression systems work in conjunction with gas shutoff valves and electrical interlocks. If these components are malfunctioning or improperly connected, they may not activate during a fire. Some technicians may miss these issues if they focus solely on the hood and extinguishing mechanisms.

5. Incomplete Maintenance Records

The FDNY requires up-to-date and accurate maintenance logs for range hood systems. Missing or incomplete documentation, such as missed inspection dates or system upgrades, can lead to automatic inspection failures—even if the system itself is in good working order.
