Water Based Fire Extinguishers
Stored pressure water extinguishers and water type extinguishers are rate A. They are good for paper or wood fires. While this limits their usefulness in many situations, they still have a specific application. They are an economical choice when deployed into appropriate areas.
- Utilizes water, antifreeze, wetting agents, and loaded stream fire protection as the agent.
- Manufactured to ANSI/UL8 and 711 standards.
- Typical uses include schools, theaters, department/retail store rooms.
- Foam fire extinguishers are rated AB. AFFF and FFFP extinguishing agent is a film-forming surfactant in water that turns into mechanical foam. On class A fires, the agent acts as both a coolant and penetrate to reduce the fire. On class B fires the agent acts as a barrier to exclude air or oxygen from the fuel. Grades of these agents are also suitable for protection of water-soluble flammable liquids (polar solvents) such as alcohols, acetones, esters, ketones, and so forth. These should be referenced specifically on the nameplate.
- Wet chemical extinguishers that are rated class K were developed for high efficiency cooking equipment with high energy input rates and fro the wide-spread use of vegetable oils with high auto-ignition temperatures. The agent works as a coolant and forms a blanket to prevent re-ignition.
Service information: Trained personnel should perform annual inspections for proper weight, condition, and pressure. Due to different requirements based on agent type, internal inspections vary and agent replacement also will vary. It is important to check the label and manufacturer's instructions and follow the requirements. Never use a different agent other than listed on the label. Hydro-testing on liquid pressure cylinders are required not less than every 5 years.
