Vehicle Fire Protection
Heavy equipment, mining vehicles, forestry machines, and other mobile equipment face significant fire risks from hydraulic leaks, fuel systems, electrical faults, and hot surfaces. Vehicle fire suppression systems provide automatic protection that can save lives and prevent total equipment loss.
Guspora designs, installs, and services vehicle fire suppression systems for a wide range of applications. We work with equipment owners, fleet managers, and contractors to ensure compliance with MSHA, insurance, and industry requirements.
Automatic Detection
Linear heat detection or spot detectors trigger suppression without operator action
Dual Agent Systems
Dry chemical for knockdown plus wet agent for cooling and re-flash prevention
Engine Shutdown
Automatic or manual engine kill switch integration

System Comparison
| System Type | Agent | Best For | Advantages |
|---|---|---|---|
| Dry Chemical | ABC or BC powder | General equipment | Fast knockdown, cost-effective |
| Dual Agent | Dry chemical + wet agent | High-hazard equipment | Knockdown + cooling/re-flash prevention |
| Liquid Agent | Foam or wet chemical | Specific applications | Cooling effect, no residue (foam) |
| Clean Agent | HFC or FK-5-1-12 | Electronics-heavy | No residue, safe for electronics |
Dry Chemical Systems
Most common for vehicle protection. ABC or BC dry chemical provides rapid flame knockdown. Suitable for most equipment types.
| Agent | ABC (monoammonium phosphate) or BC |
| Cylinder Sizes | 5 lb to 125 lb |
| Detection | Linear heat, spot detector, manual |
| Discharge Time | 8-20 seconds (size dependent) |
Dual Agent Systems
Combines dry chemical for initial knockdown with a liquid agent that provides cooling and prevents re-ignition. Required for many mining applications.
| Primary Agent | Dry chemical (knockdown) |
| Secondary Agent | Wet chemical or foam (cooling) |
| Discharge | Simultaneous or sequential |
| Best For | High-hazard, MSHA applications |
Detection Methods
Linear Heat Detection
Continuous detection cable routed through engine compartment. Detects heat anywhere along its length. Most common for vehicle applications.
Spot Detectors
Individual heat detectors placed at specific high-risk locations. Can provide faster response in known hot spots.
Manual Activation
Operator-activated systems with push button or pull cable. Often combined with automatic detection.
MSHA Requirements
Regular Service Required
Service Schedule
| Interval | Requirements |
|---|---|
| Daily (Operator) | Quick visual check: System armed light on, no visible damage to tubing or nozzles, manual actuator accessible. |
| Monthly | More thorough visual inspection: Check cylinder pressure gauge, examine detection tubing, verify nozzle positioning, test warning indicators. |
| Semi-Annual | Professional inspection recommended for high-use equipment: Complete system examination, function testing, documentation update. |
| Annual | Full professional inspection required: All semi-annual items plus weight verification, detection system test, cylinder examination, documentation for MSHA/insurance. |
| 5-6 Year | Agent replacement and cylinder service. Some manufacturers require more frequent service. Check your system requirements. |
| 12 Year | Hydrostatic test of cylinders or cylinder replacement. |
Annual Inspection Includes:
- Verify agent quantity (weight)
- Check cylinder pressure
- Inspect detection tubing/cable
- Test detection system function
- Examine all discharge nozzles
- Check mounting and brackets
- Test manual actuator
- Verify engine shutdown function
- Inspect all tubing and fittings
- Update inspection documentation
After Discharge Service:
- Inspect equipment for fire damage
- Investigate cause of fire/discharge
- Replace agent cylinder(s)
- Replace detection tube/cable
- Install new nozzle caps
- Verify all functions
- Document discharge event
- Return system to service
