DRY CHEMICAL FIRE SUPPRESSION SYSTEMS
INSPECTIONS, SALES, SERVICE, AND MAINTENANCE
WHAT ARE DRY CHEMICAL SUPPRESSION SYSTEMS?
Specialized fire protection solution designed to detect and extinguish fires in industrial environments like automotive paint booths, spray booths, and flammable liquid storage areas. Ideal for settings where flammable vapours, solvents, and combustible materials create fire hazards.
Dry chemical systems discharge a fine, powder-based agent—typically monoammonium phosphate or sodium bicarbonate—that rapidly interrupts the chemical reaction of fire, smothering flames and preventing re-ignition.
We specialize in the installation and inspection of dry chemical fire suppression systems for paint booths across Southern Ontario. Whether you operate a small auto body shop or a large industrial spray facility, we’ll ensure your system keeps your people and property safe.
SEMI-ANNUAL DRY CHEMICAL SUPPRESSION SYSTEM INSPECTIONS
The Ontario Fire Code, NFPA 17, and NFPA 33 require semi-annual inspections for all dry chemical fire suppression systems. These inspections ensure your system is fully operational, code-compliant, and ready to activate in the event of a fire.
Paint booths present unique fire hazards due to flammable vapours, overspray buildup, and multiple ignition sources.
What’s Included in a Dry Chemical System Inspection?
1. System Activation & Safety Features
-
Test automatic detection system
-
Replace fusible links as required
-
Verify manual pull station functionality
-
Inspect electrical and mechanical shutdown interlocks (fans, lights, etc.)
2. Discharge System
-
Inspect nozzles for clogs, alignment, and proper coverage over hazard areas
-
Check discharge piping and fittings for wear or corrosion
-
Confirm proper agent distribution pattern
3. Agent Cylinders & Pressure Levels
-
Inspect cylinder condition and mounting
-
Verify pressure gauge readings
-
Check for correct dry chemical agent type and quantity
4. System Signage & Accessibility
-
Ensure clear operating instructions are posted near system controls
-
Confirm access to manual actuation devices is unobstructed
WHY FREQUENT INSPECTIONS ARE ESSENTIAL
Facilities that handle flammable vapours, liquids, or combustible materials—such as paint booths, spray finishing areas, and chemical storage rooms—are considered high-risk environments.
During each semi-annual service, technicians check for:
Clear and unobstructed nozzles
Overspray, dust, and airborne particles can block nozzles and prevent proper discharge coverage.
Correct agent levels and pressure
Low pressure or insufficient agent volume can result in failed suppression or incomplete extinguishment.
Fire code and insurance compliance
Inspections are required by the Ontario Fire Code, NFPA 17, and NFPA 33. Failure to comply may result in fines, denied claims, or operational shutdowns.
SUPPRESSION AGENT & DISTRIBUTION
-
Dry Chemical Agent – A fine powder designed to interrupt the chemical reaction.
Agent Storage Cylinder – A pressurized steel cylinder that stores the dry chemical agent.
Discharge Piping and Nozzles – A network of steel piping connected to strategically placed nozzles.
DETECTION
- Heat Sensors/Fusible Links – These are temperature-sensitive devices that trigger the system when a fire is detected.
- Mechanical or Electric Detection Line – A network of cables or tubing that detects heat and activates the suppression system.
CONTROL & ACTIVATION
- Manual Pull Station – Allows staff to activate the system manually in case of an emergency.
- Automatic Release Mechanism – Engages the system when heat sensors detect a fire, releasing the suppression agent.
ALARM & MONITORING
- Alarm System Connection – Some systems integrate with fire alarm panels to alert staff and emergency services.
- Audible/Visual Alarms – Alerts occupants when the system is activated.
SUPPRESSION SYSTEM INSTALLATIONS
If you’re launching a new operation involving flammable liquids, vapours, or combustible materials—such as a paint booth or industrial spray area—a properly installed dry chemical fire suppression system is essential for meeting fire code and protecting your investment.
Adding and/or Modifying Equipment?
Changes to your facility layout or the addition of new spray equipment, ventilation systems, or storage areas may require updates to your fire suppression system.
