Our wet chemical fire extinguisher is specially designed to tackle Class F fires involving cooking oils and deep fat fryers, making it the essential choice for kitchens in restaurants, cafés, holiday parks, and residential settings. The fine spray gently lays down a thick foam blanket, rapidly cooling the burning oil and preventing re-ignition without splashing. Safe, reliable, and fully compliant with British Standards, this extinguisher is also effective on Class A fires, providing wider protection for kitchens and food preparation areas. Easy to operate and eco-friendly, it offers peace of mind where cooking risks are present.

- Monthly Check: Confirm the extinguisher is in its correct location, visible, and undamaged. Make sure the pressure gauge is in the green and the lance is clean and securely attached.
- Annual Service: A qualified technician must inspect and service the extinguisher once a year, checking the weight, internal pressure, and overall condition.
- 5-Year Extended Service: Wet chemical extinguishers require a full discharge and refill every 5 years, along with a thorough internal inspection.
