Trolley Mounted Fire Extinguishers for Industrial & High-Risk Environments

Trolley mounted fire extinguishers provide larger quantities of extinguishing agent for specialist and higher-risk environments where standard hand-portable extinguishers alone may not provide sufficient firefighting capacity.

Also known as wheeled or mobile fire extinguishers, these units are designed to be moved to the point of use and are commonly associated with industrial, aviation, manufacturing, fuel-handling and other specialist fire risks.

Kings Fire can assess the risks present, advise on suitable trolley mounted extinguisher provision, source and commission appropriate equipment and provide ongoing servicing.

What Is a Trolley Mounted Fire Extinguisher?

A trolley mounted fire extinguisher is a larger-capacity mobile extinguisher mounted on wheels so that it can be moved by an operator to the location of a fire.

Depending on the model and extinguishing medium, units can contain substantially more extinguishing agent than conventional portable extinguishers and normally incorporate a hose, horn or discharge lance to allow the operator to apply the extinguishing medium from a suitable position.

Their purpose is not simply to provide a bigger version of an ordinary extinguisher. They are specialist firefighting appliances intended for risks where additional extinguishing capacity, discharge duration or range may be required.

Where Are Trolley Mounted Extinguishers Used?

Trolley mounted extinguishers are most commonly considered for larger or higher-hazard commercial and industrial environments.

Typical applications may include aircraft hangars, airports and aviation facilities, fuel storage and handling areas, manufacturing plants, engineering facilities, warehouses, process industries and other sites where significant flammable-liquid, machinery or specialist fire risks are present.

They may also be appropriate where the scale of a particular fire risk means that a conventional portable extinguisher could provide insufficient extinguishing capacity.

The requirement should always be established from the actual fire hazards and operational environment rather than installing a trolley unit simply because the premises are large.

Types of Trolley Mounted Fire Extinguishers

Trolley mounted extinguishers are available with different extinguishing media depending on the fire risks being protected.

CO2 trolley units can provide larger quantities of carbon dioxide for appropriate Class B and electrical equipment risks where a clean, non-residue extinguishing agent is desirable.

Dry powder trolley units are available for a range of industrial applications, with the exact powder selected according to the fire classes and substances involved. Specialist high-performance powders such as Monnex may also be available for demanding flammable-liquid risks.

Foam trolley units may be appropriate for certain Class A and Class B fire risks where a larger quantity of suitable foam extinguishing agent is required.

The correct medium, capacity and fire rating must be selected for the particular risk rather than choosing a trolley unit on size alone.

Trolley Units to BS EN 1866

Wheeled or mobile fire extinguishers are covered by BS EN 1866-1.

This standard addresses the design, performance and testing of mobile fire extinguishers, which are distinct from the smaller hand-portable extinguishers normally manufactured to BS EN 3.

Where Kings Fire specifies a trolley mounted unit, the individual product, fire rating and manufacturer's certification will be considered alongside the particular fire risks and operating environment.

Choosing the Right Trolley Mounted Extinguisher

Selecting a trolley mounted extinguisher requires more than simply deciding how much extinguishing agent is required.

Consideration should be given to the materials and processes involved, likely fire size, extinguishing medium, fire rating, discharge characteristics, operator access and the route over which the unit would need to be moved.

Floor surfaces, steps, doorways, external terrain and the ability of personnel to safely manoeuvre the unit can all affect whether a wheeled extinguisher is a practical solution.

For some higher-risk environments, a trolley mounted extinguisher may form only one part of the overall fire protection arrangements and should not automatically be regarded as an alternative to an appropriate fixed firefighting system.

Professional Supply, Commissioning & Servicing

Kings Fire can advise on trolley mounted fire extinguisher provision for specialist commercial and industrial environments.

We can review the fire risks and operating conditions, identify an appropriate extinguishing medium and capacity, source suitable equipment and commission it at the premises.

Trolley mounted extinguishers also require ongoing inspection and maintenance. Kings Fire can provide servicing where applicable in accordance with the particular equipment and manufacturer's requirements.

For wider portable firefighting requirements, trolley units can be considered alongside the premises' conventional fire extinguisher provision.
