Portable Fire Extinguishers

Portable fire extinguishers are designed to fight small incipient fires or unusual ones that are not easily put out by water. The use of portable fire extinguishers is important for two reasons. First, firefighters use them on certain unusual fires that hoselines cannot put out and, second, citizens can use them to fight small fires before the fire department arrives. Firefighters must know how to use them and be able to teach others to use them. When used by untrained persons, fire extinguishers have been ineffective and dangerous, and have created deadly delays in calling the fire department. Proper instruction on the use of fire extinguishers can improve the effectiveness of a fire department and reduce the costly effects of fire.

Firefighters usually use hoses and water to fight fires and extinguishers are used only occasionally. Still when an extinguisher is needed, knowledge and skill are required if the unit is to be used properly and this requires practice. Firefighters must pay careful attention in training sessions and practice using extinguisher-operating skills whenever possible.

Many types of fire extinguishers are available for purchase and use today. Which is the best type of extinguisher depends on many factors and each should be considered prior to placing an extinguisher to use. The wrong extinguisher can be worse than no extinguisher.

Factors for selecting an extinguisher are the fuel, the people using it, and the building or place where it will be used. The first factor to consider is the type and amounts of fuels present that reveal what kind of fire to anticipate. The amount of fuel determines size; the wrong size extinguisher will not completely extinguish the fire.

Another factor is the construction of the building and its occupancy that identifies the hazards and conditions to protect.

A final factor would be the type of equipment protected and its ability to be cleaned without excessive damage.
