HANDHELD + WHEELED
Portable Fire Extinguishers
At the incipient stage of a developing fire, a portable fire extinguisher is intended to be quickly carried or wheeled to the hazard location, where its extinguishing agent is discharged to suppress further fire growth.
Unlike fixed fire suppression systems that designed to operate automatically, fire extinguishers are movable devices that require manual operation.

Wheeled CO₂ portable fire extinguishers recharged and serviced at the Fire Defense extinguisher and cylinder service facility in accordance with NFPA 10 requirements.
The incipient stage represents the earliest phase of a fire before it intensifies into a larger uncontrolled event.
Fire extinguishers are not designed to control fires that have grown beyond this initial stage. Therefore, only a narrow window of time exists in which an extinguisher can effectively suppress a fire.

Training + Education
The optimal time to use a fire extinguisher is during the beginning stage of a fire, when it is still small and localized. Because extinguishers contain a limited amount of extinguishing agent, correct operation is critical.
Using the wrong type of extinguisher or improper technique for a specific hazard can result in electrical shock, rapid fire spread, or loss of control. Personnel should be trained in extinguisher use and educated on the limitations and hazards associated with fire response in accordance with OSHA requirements.
Fire Defense provides training and educational programs for companies and individuals focused on the proper use of portable fire extinguishers.
Hands-on instruction and live demonstrations using actual extinguishers, either through controlled live fire scenarios or digital simulation, are available depending on location and customer preference.

For a portable fire extinguisher to reliably suppress an incipient fire, several critical factors must be addressed.
Selection: correct type, size, and quantity of extinguisher(s) for the specific fire hazards, occupancy group, and location conditions present.
Installation: mounted in designated and readily accessible locations in accordance with mounting height, travel distance, and visibility requirements.
Maintenance: fully charged, inspected, and serviced at intervals established by codes, standards, and manufacturer procedures so it remains operationally ready.
Operation: personnel trained and educated in proper extinguisher use.
Questions & Answers
When should a portable fire extinguisher be replaced instead of serviced?
Extinguishers should be replaced if they are non-rechargeable, fail inspection or hydrostatic testing, show signs of damage or corrosion, or no longer meet the required hazard classification or rating.
