Wet Chemical Fire Extinguishers Australia
Wet Chemical Fire Extinguishers for Commercial Kitchens, Restaurants, Cafés, Food Trucks and Cooking Oil Fire Protection
Wet chemical fire extinguishers are specifically designed to combat fires involving cooking oils and fats, making them one of the most important fire safety products in commercial kitchens and food preparation environments. From restaurants and cafés through to hotels, clubs, food trucks, aged care facilities and institutional kitchens, wet chemical extinguishers provide specialised protection for one of the most dangerous fire hazards found in modern workplaces.
Unlike general-purpose fire extinguishers, wet chemical extinguishers are engineered to tackle high-temperature cooking oil fires that can rapidly spread and reignite if the incorrect firefighting method is used. For this reason, they are commonly regarded as the preferred fire extinguisher for commercial cooking environments throughout Australia.
At Industro, we supply wet chemical fire extinguishers suitable for hospitality venues, commercial kitchens, catering businesses, educational facilities, healthcare providers and food service operations nationwide. Whether you operate a small café or a large commercial kitchen, our range provides reliable fire protection designed to address the unique hazards associated with cooking oils and fats.
What Is a Wet Chemical Fire Extinguisher?
A wet chemical fire extinguisher contains a specialised extinguishing agent designed specifically for cooking oil and fat fires.
When discharged onto burning oil, the extinguishing agent reacts with the surface of the oil to create a cooling and smothering layer. This process helps suppress flames, reduce temperatures and minimise the risk of re-ignition.
Wet chemical extinguishers are specifically developed for environments where cooking oils and fats are regularly used.
Common applications include:
- Commercial kitchens
- Restaurants
- Cafés
- Hotels
- Clubs
- Food courts
- Food trucks
- Catering operations
- School canteens
- Aged care facilities
What Types of Fires Can a Wet Chemical Fire Extinguisher Be Used On?
Class F Fires
The primary purpose of a wet chemical extinguisher is to combat Class F fires.
Class F fires involve:
- Deep fryer oils
- Vegetable oils
- Cooking fats
- Animal fats
- Commercial cooking oils
These fires burn at extremely high temperatures and can become highly dangerous if inappropriate extinguishing methods are used.
Class A Fires
Wet chemical extinguishers may also provide protection against certain Class A fires involving:
- Paper
- Cardboard
- Timber
- Textiles
However, their primary purpose remains protection against cooking oil and fat fires.
Why Wet Chemical Fire Extinguishers Are Essential in Commercial Kitchens
Commercial kitchens present a unique fire environment.
Unlike offices, warehouses and workshops, hospitality venues frequently contain:
- Deep fryers
- Commercial cooktops
- High-temperature oils
- Open flames
