Introduction

In the restaurant industry, fire safety isn’t optional—it’s essential. Kitchen fires are among the leading causes of property damage and injuries in commercial settings. The first line of defense? A well-maintained kitchen hood suppression system. But simply having a system installed isn’t enough; regular, professional inspections are critical to stay compliant, protect your staff and guests, and avoid costly violations or downtime.
This guide covers what you need to know to prepare for a kitchen hood suppression system inspection—so you can keep your doors open and your operations safe.

TLDR - Quick Guide

Routine kitchen hood suppression system inspections are required by law.
Key focus: system cleanliness, unobstructed nozzles, correct chemical levels, and up-to-date inspection tags.
Most violations result from blocked nozzles, missing or expired tags, and grease buildup.
Always schedule inspections with certified professionals.
Proactive maintenance prevents shutdowns and fines.

Detailed Breakdown

1. Why Kitchen Hood Suppression Inspections Matter

Kitchen hood suppression systems are designed to detect and suppress fires before they can spread. Local fire codes and the National Fire Protection Association (NFPA 96) mandate regular inspections for all commercial kitchens. Skipping or delaying inspections can lead to failed health and fire inspections, insurance claim denials, or even business closures after an incident.

2. Common Fire Hazards in Commercial Kitchens

Grease Accumulation: Built-up grease in hoods, ducts, and filters is a major ignition source.
Improper Equipment Placement: Cooking appliances moved or added without updating suppression coverage.
Blocked Nozzles: Items placed near hood outlets can block suppressant discharge.
Untrained Staff: Staff unfamiliar with system operation or fire response protocols.

3. Minimum Requirements for Passing Inspection

Before your scheduled inspection, make sure your system meets these minimum requirements:

System Cleanliness: All hoods, ducts, and filters must be free of grease and debris.
Nozzle Accessibility: Nozzles must remain unobstructed by equipment or supplies.
Proper System Charging: Chemical canisters or CO2 cartridges should be at the correct pressure and fully operational.
Manual Pull Stations: Clearly marked and easily accessible.
Up-to-Date Tags: Each system component must display a current inspection tag, dated and signed by a certified technician.
Correct Coverage: Suppression nozzles must be correctly positioned over all cooking appliances.

4. Who Is Responsible?

Restaurant Owners/Managers: Responsible for daily maintenance and ensuring inspection schedules are kept.
Service Providers (AAA Fire Protection): Certified to inspect, test, and maintain systems in compliance with NFPA and local codes.
Staff: Should be trained to respond quickly to fires and know how to activate manual pull stations.
