Wet chemical fire extinguishers are specifically designed to tackle Class F fires involving cooking oils and fats. They are a critical safety requirement in commercial kitchens, where traditional extinguishers are ineffective or unsafe.
Why it works: the wet chemical reacts with hot oils to create
a soapy layer that smothers flames, cools the oil surface, and helps prevent
dangerous re-ignition.
✅ Key benefits
- Essential for Class F fires involving cooking oils and fats
- Prevents re-ignition through chemical saponification
- Safe to use on deep fat fryers and commercial cooking equipment
- Widely required to meet commercial kitchen safety standards
🍳 Best for
Commercial kitchens, restaurants, takeaways, catering facilities, food production areas and any environment using deep fat fryers or large volumes of cooking oil.
⚠️ Important considerations
Wet chemical extinguishers are not a general-purpose solution and should only be used where cooking oil fire risks exist. They contain chemical agents and are not suitable for electrical or flammable liquid fires outside kitchen settings.
