Wet Chemical Fire Extinguishers

What is a Wet Chemical Fire Extinguisher?

Vigil Wet Chemical Fire Extinguishers provide essential protection against Class F fires. This involves cooking oils and fats commonly found in commercial kitchens and catering environments. This is the only type of extinguisher that will safely extinguish cooking-related fires involving oils.

Featuring a lance, this Class F extinguisher helps to keep the user at a distance from the fire to avoid burn injuries. It emits a spray that prevents oils from splashing and blankets fires to prevent their spread.

What is a Wet Chemical Fire Extinguisher Used For?

Designed to tackle high-temperature grease fires safely and effectively, these extinguishers discharge a fine spray of potassium solution. This rapidly cools the burning oil and forms a soapy layer on the surface. This chemical reaction — known as saponification — seals the surface of the fuel to prevent re-ignition. Offering long-lasting fire suppression, it's an ideal unit for kitchens found in small mobile cafes to commercial settings.

Engineered to meet the highest UK and European standards, Vigil Wet Chemical Fire Extinguishers are EN3-certified and CE-marked. Manufactured to ensure reliability in demanding kitchen environments, these extinguishers have an impressive 75F fire rating. Their 13A fire rating also means they're suitable for use on Class A fires, involving paper and combustible solids.

What Colour is a Wet Chemical Fire Extinguisher?

The Vigil Wet Chemical Extinguisher features a bright yellow label, which reads as "Wet Chemical". Alongside this information, you will also find its fire rating and purpose on the front of the unit.

Each unit features a corrosion-resistant stainless steel cylinder, a reinforced hose, and a long lance applicator. The controlled discharge allows for precision application, ensuring that the extinguishing agent coats the burning surface evenly. This reduces the risk of cooking oils splashing or exacerbating fire spread.

Made in 6-litre models, these units suit both small catering outlets and large commercial kitchens. Their compact design and wall-mounting bracket ensure easy installation in compliance with kitchen safety regulations.

How to Maintain Wet Chemical Extinguishers

Maintenance is straightforward and fully in line with UK fire safety standards. Routine servicing ensures kitchen fire extinguishers remain fully charged and ready for use. The pressure gauge provides an instant visual check of operational status. 

The durable construction and long-lasting internal lining withstand the humid, heat-intensive conditions often found in professional kitchens. With proper care, Vigil Wet Chemical Fire Extinguishers deliver reliable, long-term fire protection for catering and hospitality settings.

It’s important to note that wet chemical extinguishers should never be used on electrical fires or flammable liquid fires. For comprehensive protection, complement units with CO₂ or foam extinguishers in adjacent areas where different fire risks may exist.

Vigil Wet Chemical Fire Extinguishers are a critical component of any professional kitchen’s fire safety plan. Their superior performance against high-temperature oil fires makes them a trusted choice for chefs and fire safety professionals. 

When installed and maintained correctly, they provide rapid, dependable response and help protect lives, property, and business continuity.
