NFPA 96 Compliant Semi-Annual Inspections Title 19 Licensed 24/7 Emergency Response

Hood Suppression You Can Rely On

Commercial kitchen fires are the leading cause of restaurant fires in California. Your hood suppression system is the last line of defense between a flare-up and a full kitchen loss. Delta Fire Equipment installs, services, inspects, and recharges wet chemical suppression systems for commercial cooking operations across all of California.

Health departments, fire marshals, and insurance carriers all require current semi-annual suppression system certifications. We keep your kitchen compliant — and your doors open.

  • Semi-annual inspections per NFPA 96 requirements
  • Wet chemical agent recharging and cylinder replacements
  • Nozzle coverage verification and hood interlock testing
  • Certificate of inspection provided — accepted by health dept. & fire marshal
  • New system installation and replacement for aging systems
  • Emergency response available when a system discharges

The Stakes in a Commercial Kitchen

Cooking fires account for nearly 60% of restaurant fires nationwide. A working, certified suppression system stops these fires within seconds — before they reach the hood plenum and flue. An uninspected or discharged system is one flare-up away from a total loss and potential closure.

How Kitchen Suppression Systems Protect Your Operation

Modern wet chemical systems activate automatically and shut off fuel simultaneously — stopping a cooking fire in seconds.

01

Detection

Fusible link detectors or electronic sensors in the hood plenum detect a fire, triggering the suppression system. Links are calibrated to activate at specific temperatures — typically 280°F to 500°F depending on your cooking equipment.

02

Agent Discharge & Fuel Shutoff

The wet chemical agent discharges through strategically placed nozzles, blanketing the cooking surface, plenum, and grease filters in a fire-suppressing foam. Simultaneously, a shunt valve cuts gas supply to all protected appliances.

03

Post-Discharge & Recharge

After discharge, the system cannot be used until it is cleaned, inspected, and recharged. Delta technicians respond quickly to restore your system and get your kitchen back in operation — minimizing downtime.

Wet Chemical & Dry Chemical Systems

We install and service all major kitchen suppression system configurations used in California commercial kitchens.

Wet Chemical Suppression Systems

The current standard for commercial cooking operations under NFPA 96. Wet chemical agent (potassium carbonate-based) reacts with hot grease to form a soapy foam that smothers and cools a fire simultaneously — making re-ignition nearly impossible.

Restaurants Hotels Cafeterias NFPA 96 Standard

Dry Chemical Suppression Systems

Legacy systems using dry chemical agent are still found in many existing California kitchens. We service and inspect these systems, and can advise on retrofit or replacement with modern wet chemical systems where required by code.

Kitchen Suppression Services

From a brand-new installation to an emergency post-discharge recharge, Delta handles every aspect of your kitchen suppression system.

New System Installation

We design and install suppression systems sized for your specific cooking equipment layout — from single fryers to complex multi-appliance hood arrays.

  • Coverage design per cooking appliance footprint
  • Nozzle placement per manufacturer specs
  • Gas valve and electrical interlock installation

Semi-Annual NFPA 96 Inspection

NFPA 96 and most health departments require suppression systems to be inspected every six months. We inspect, test, and certify your system — and provide documentation for your records and inspectors.

  • Nozzle condition and coverage verification
  • Fusible link and detection system test
  • Manual pull station, interlocks & agent cylinder check

Wet Chemical Recharge & Cylinder Service

After any discharge — accidental or fire-related — the system must be fully recharged before it can protect your kitchen again. We respond quickly to minimize kitchen downtime.

  • Agent recharge and cylinder hydrostatic testing
  • Nozzle and line cleaning post-discharge
  • System reset and re-commissioning

Repair & Component Replacement

Damaged nozzles, failed fusible links, corroded piping, or malfunctioning gas valves — we diagnose and repair suppression system deficiencies found during inspection or after a discharge event.

  • Nozzle and link replacement
  • Piping and fitting repairs
  • Gas valve and interlock replacement

System Upgrade & Replacement

Older dry chemical systems or systems with outdated components may no longer be supportable or code-compliant. We assess your system and provide options for upgrade or full replacement.

  • Code compliance review for existing systems
  • Dry-to-wet chemical conversion design
  • Full system replacement with minimal downtime

Health Department & Fire Marshal Compliance

We provide the documentation your health department and local fire marshal need — including the semi-annual inspection certificate, deficiency reports, and correction records.

  • Inspection certificates accepted statewide
  • Deficiency documentation and correction records
  • Coordination with AHJ and health inspectors

The Regulations That Govern Your Kitchen System

California commercial kitchen suppression is governed by multiple overlapping codes. Non-compliance puts your health permit, fire certificate, and insurance coverage at risk.

NFPA 96

Standard for Ventilation Control & Fire Protection of Commercial Cooking Operations

The primary national standard for commercial kitchen fire safety. Requires semi-annual inspection and service of hood suppression systems and specifies installation, cleaning, and maintenance requirements for all components.

Title 19

California Code of Regulations — Fire Safety

California state fire safety regulations adopt NFPA standards with local amendments. Title 19 compliance is required for all California commercial cooking operations. Our technicians are certified under Title 19.

Health Dept.

County Health Department Requirements

Most California county health departments require a current (within 6 months) suppression system inspection certificate as a condition of your food service permit. An expired certificate can result in immediate closure.

IFC / CBC

International Fire Code & California Building Code

Local fire departments and building departments reference IFC and CBC requirements during inspections. We ensure all installations and repairs satisfy both state and local code interpretations.

What Happens Without a Current Certificate

  • Health permit risk: Many counties will not renew or will suspend your food service permit if your suppression system certificate is expired.
  • Insurance exposure: A kitchen fire with an uninspected system may give your insurer grounds to deny a claim or reduce coverage.
  • Fire marshal citation: California fire marshals cite suppression system deficiencies and expired inspections as some of the most common restaurant violations.
  • Forced closure: In some jurisdictions, an un-certified suppression system is grounds for immediate closure until the system is brought into compliance.
  • Liability: If a fire occurs and your system was not properly maintained, you may face personal liability exposure beyond your insurance limits.
