How Vehicle Fire Suppression Systems Prevent Catastrophic Equipment Loss

Heavy-duty vehicles are an integral part of the work done in many industries. These vehicles face unique fire risks that can lead to expensive losses. They work under harsh conditions, such as extreme temperatures and with combustible materials, which increase their susceptibility to fires. Vehicle fire suppression systems can prevent catastrophic loss from fire and protect your valuable assets. 

Fire Risks for Heavy-Duty Vehicles

Some of the most common fire risks on heavy machinery include: 

• Fuel Leaks: Most vehicles run on diesel or gasoline, both of which are extremely flammable. Their engines run hot, and specialized features such as hydraulic lift systems can provide an ignition source if there are fuel leaks from injectors, fittings, or fuel lines. 
• Electrical Failures: Heavy machinery and commercial transport vehicles typically include complex electrical systems that contain multiple wires and connections. Failure in any of these parts, including faulty wiring, short circuits, or eroded insulation, can ignite a fire. 
• Flammable Materials: Industrial vehicles often work with flammable debris that can build up over time. When this debris accumulates, it can easily be ignited by a stray spark or high temperatures caused by friction between components. 
• Mechanical Failures: The mechanical components of a commercial vehicle undergo a lot of stress. Overheated engines, friction between parts such as hydraulic arms, and other mechanical issues can ignite fires, particularly when combined with fuel leaks or flammable materials. 
• Turbochargers and Exhaust System Failures: Turbochargers can reach extremely high temperatures. These high temperatures can ignite fires from leaking oil, cracked exhaust manifolds, or incomplete combustion in exhaust systems. 
• Cargo-Related Hazards: Often, the biggest fire hazard on commercial transport vehicles is the load they’re carrying. Flammable materials, such as chemicals, can easily combust if exposed to an ignition source. Organic materials, such as hay or compost, can spontaneously combust under the right conditions. 

Elements of a Vehicle Fire Protection System

Vehicle fire suppression system manufacturers have served as your first line of defense in the event of a fire. These systems can react as soon as a fire is detected, regardless of the state of the vehicle or any electrical or mechanical failures. The typical elements in a vehicle fire protection system can include: 

Detection Systems

There are several types of detection systems used to detect fires in vehicles. These include heat sensors, smoke detectors, or infrared sensors. They can be placed throughout the vehicle, particularly in critical areas such as the engine compartment, for rapid fire detection. 

Activation Mechanism

When the detection system identifies a potential fire hazard, the activation mechanism automatically triggers the suppression process. Many fire suppression systems also include a manual activation option.

Extinguishing Agents 

Distribution Systems

A network of pipes, hoses, and nozzles is used to disperse the extinguishing agent where it’s needed. The exact placement will depend on the type of vehicle, since the system needs to ensure access to all vulnerable areas. 

Control Panel

Many vehicle fire suppression systems contain a centralized control and monitoring system. This panel can display information about the system and monitor all of the elements involved. 

Industries That Can Benefit From Vehicle Fire Suppression Systems 

A fire protection system is a good idea for any vehicle, but there are some industries that are particularly high risk due to the types of vehicles involved or the environmental risk. These include: 

• The mining industry, including vehicles such as haul trucks, dozers, drills, and loaders
• The oil and gas industry, including vehicles such as blenders and frac pumps
• The logging industry, including equipment such as feller bunchers, log loaders, de-limbers, and wood chippers
• The steel industry, including equipment such as slag carriers and loaders 
• The waste handling industry, including equipment such as compactors, excavators, and loaders 
• Other industries, such as construction, transportation, coal, military, public transportation, and agriculture
