Water Mist Fire Extinguishers

Water mist fire extinguishers discharge water as a very fine mist that cools the fire with little collateral damage, making them a clean, versatile choice for busy internal areas. Choose from CheckFire CommanderEDGE, Firechief PureSafe, Jewel E-Series and Ceasefire models.

How to choose a water mist fire extinguisher

• Read the rating, not just the type. Ratings vary by model: most here cover Class A (solids) and Class F (cooking oils and fats), and several Jewel models also carry Class B (flammable liquids). Water mist tackles Class F fires by cooling, so for deep fat fryers compare with our wet chemical extinguishers.
• Check the electrical data for each model. Ceasefire states its portable watermist extinguishers are suitable for live electrical equipment up to 1000V from a distance of 1 metre, and Firechief lists a 35kV dielectric test for PureSafe watermist; always check the product data.
• Pick a practical size. Smaller units are lighter to carry, 6 and 9 litre units hold more agent, and wheeled units suit large areas. Confirm the right mix with your fire risk assessment or a competent person.

Complete the fire point with fire extinguisher stands and cabinets, and identify each unit with fire extinguisher ID signs. For where each type fits, read our fire extinguisher colours and types: where a water mist extinguisher fits guide and which fire extinguisher for electrical fires.

Water mist fire extinguisher FAQs

What is a water mist fire extinguisher?

It is an extinguisher that uses a special nozzle to break water into very fine droplets. The mist cools the fire, and because the water is so finely divided it causes little collateral damage.

What type of fire is a water mist extinguisher used for?

Most models in this range are rated for Class A and Class F fires, and some Jewel models also for Class B. Always check the individual extinguisher's rating.

Can you use a water mist extinguisher on electrical equipment?

Only where the manufacturer says so for that model, within the stated limits. For example, Ceasefire states its portable watermist units are suitable for live electrical equipment up to 1000V from a distance of 1 metre.

What colour is a water mist fire extinguisher?

A water mist extinguisher has a red body with a white label or colour-coded area identifying the agent.

Can a water mist extinguisher be used on cooking oil fires?

Models rated for Class F can be used on cooking oil and fat fires. Check the F rating on the label and compare it with a wet chemical extinguisher for commercial kitchens.

What sizes do water mist fire extinguishers come in?

Portable models range from 1.4 litres to 9 litres, and wheeled units come in 25, 50 and 100 litres. Your fire risk assessment should confirm the size and number you need.

Is water mist the same as plain water?

No. Water mist uses a fine spray to cool the fire and is rated for a wider range of fire classes than a plain water extinguisher, which is for Class A fires only.
