Wet Chemical Class F Fire Extinguishers
Wet chemical Class F fire extinguishers are made for cooking oil and fat fires in commercial kitchens, school kitchens, restaurants and takeaways. They help you tackle fryer fires more safely because the discharge cools the oil and creates a sealing layer over the surface, reducing oxygen and helping prevent re-ignition. They also carry a Class A rating for materials such as wood, paper and textiles.
Where Wet Chemical Extinguishers Should Be Placed
Install them at kitchen exits, beside fryer areas and near cooking lines where oils or fats are used, but not so close that you would need to move through flames to reach them. They are most appropriate for commercial kitchens, school catering spaces, restaurant kitchens and takeaways where Class F risk is present and fast access matters. Keep the unit visible from the working area so you can identify it immediately in a high-stress kitchen incident.
Mounting Height, Fire Test Size And Discharge Facts
A 6 litre wet chemical extinguisher is commonly wall mounted with the carry handle around 1 metre or 3.3 feet from floor level, or placed on a stand where wall fixing is unsuitable. A 75F rating means it has been tested on a fryer fire containing 75 litres of oil, with published guidance linking that to a maximum surface area of about 0.11m². The supplied discharge time of 51.3 seconds gives you a longer, more controlled application than many smaller units.
What Correct Kitchen Placement Helps You Achieve
When this extinguisher is installed in the right kitchen positions, you improve first-response control for fryer fires, reduce panic around specialist oil-fire risks and give staff a clearer, safer option for tackling the fire type it is designed for.
- ✅ Better cover for deep fat fryer and cooking oil fire risks
- ✅ Longer discharge helps controlled application across the oil surface

- ❌ Putting it directly beside the fryer where flames could block access
- ❌ Hiding it behind doors, bins or catering equipment
- ❌ Mounting it too high for quick and safe removal
- ✅ Position it on the exit route from the cooking area
- ✅ Pair it with the rest of the kitchen fire safety setup required by your risk assessment
- ✅ Choose the wall bracket for fixed kitchens or a stand where drilling is impractical

Compare fire extinguishers by risk type
Where your site also needs smaller foam cover, compare 2 litre foam extinguishers for nearby workspaces alongside Class F provision. Useful when kitchens sit close to offices or stores.
For wider general workplace areas, consider 6 litre AFFF foam fire extinguishers as part of your wider fire point layout. Helpful for shared rooms away from cooking oil risks.
If larger capacity foam cover is needed elsewhere, review 9 litre AFFF extinguishers for larger spaces before completing your plan. Useful for open work areas and bigger premises.
For smart visible locations, compare stainless foam extinguishers for public interiors where appearance and fire readiness both matter. Suitable for customer-facing areas outside kitchen risks.
To review foam options separately from Class F needs, browse foam fire extinguisher categories for workplaces and select by location. Helpful when you are separating cooking hazards from general fire cover.
