Does Our Facility Require a Wheeled Extinguisher?
There is more involved in operating wheeled extinguishers than simple hand held extinguishers thus, personnel must be trained in there use.
If high hazard areas exist and there are not enough personnel on hand to operate several handheld units, wheeled extinguishers must be considered. This is because the wheeled extinguisher provides greater flow rate (more extinguishing agent per second), greater range, and greater capacity (holds more agent). The wheeled extinguisher is usually chosen because of the magnitude of the fire a special hazard, or a large extra hazard could produce.
The magnitude of the fire likely to occur also makes it necessary that wheeled extinguishers only be operated by those who have experience in using this type equipment, have used the equipment in training on a live fire, or have at least received special training.
The need for a wheeled extinguisher would also affect our selection of fire equipment service companies. Servicing this type unit, even the yearly maintenance of a wheeled extinguisher, requires specialized equipment. Specific instruction is also needed. The extinguisher company representative servicing a wheeled extinguisher should have the specialized instructions for this type extinguisher. Even a detail such as knowing how the hose must be placed on the rack may determine whether or not the unit will perform correctly when needed. See our article: How to Choose the Best Fire Extinguisher Service Company.
If risk assessment indicates the need for a wheeled unit, here are some factors to consider in selecting an extinguisher:
What class fire hazard is to be protected (ABC, BC)?
Is it to be outside?
Will we choose rubber tires?
Would wide-rimmed wheels be best?
Is to be indoors?
Will it fit through doorways and any narrow passages?
Do you have an approved place to park it?
