Water (H20) & Water Mist Fire Extinguishers
Water fire extinguishers are a common and cost-effective option for fighting Class A fires. These include fires whose fuel source includes:
- Wood
- Paper
- Trash
- Plastics
- Fabric
- Rubber
Importantly, water fire extinguishers should not be used on electrical fires (Class C) because of a higher risk of electrocution. Water extinguishers are also not effective on fires caused by flammable liquids (Class B) or cooking oils (Class K). Water will have the opposite effect and can actually cause the spread of flames on these fires. Water Mist fire extinguishers on the other hand can be used on Class A fires and where the potential for a Class C fire exists. These fire extinguishers use a specialized nozzle and de-ionized water to provide safety from electrical shock. The fine mist also aids in the cooling effect of the agent and helps to reduce the scattering of burning material. Water fire extinguishers come in the standard 2.5 GAL size from Amerex, Ansul and Strike First Corporation.

Water and water mist fire extinguishers tend to be more expensive than small or moderately-sized ABC extinguishers. They are made of stainless steel construction and in the case of water mist fire extinguishers, are specialized units suitable for use in sensitive MRI machine environments.
Dry-chemical (powder) extinguishers use powder-based dry suppression agents that form a barrier between the oxygen and the fuel agent to extinguish a fire and are effective on class ABC fires. Powder fire extinguishers will leave behind a residue after discharge. Water-based fire extinguishers put out fires by removing heat from the chemical reaction and clean-up of the agent is less troublesome as it is water.
No, water extinguishers should not be used on electrical fires. Use on Class C fires can result in electrical shock to an individual trying to extinguish an electrical fire.
Yes, water mist extinguishers are designed to be used primarily on Class A fires. However, they can also be used where Class C fires have the potential to occur. The super fine de-ionized water mist produced by the extinguishing wand provides safety from electrical shock, unlike a water fire extinguisher.
The advantage of water mist fire extinguishers is that their suppression agent is the most economical to refill and is completely natural. Mist fire extinguishers utilize de-ionized water, making them safe for use in sensitive areas such as hospitals, libraries, and telecommunication facilities. These extinguishers are also typically easy to use, maintain, and service.
Water spray fire extinguishers work by spraying a jet of water at combusting materials, effectively cooling them and preventing reignition. Meanwhile, water mist fire extinguishers use microscopic water molecules that are so small they smother and cool fire without further damaging the burning material.
Water mist fire extinguisher pressure varies depending on the make and model of the extinguisher. Most models will operate within the range of 12 to 35 bars of pressure within the tank. The pressure of the tank helps to push the water molecules through the extinguishing wand.
