What Makes Wet Chemical Fire Extinguishers Unique?

Wet chemical fire extinguishers are specialized equipment that utilize a mixture of water and potassium acetate to effectively suppress fires. Unlike traditional extinguishers that may not be effective against grease fires, these extinguishers smother the flames and create a barrier between the fuel and oxygen. This unique chemical reaction works exceptionally well against Class K fires, which are common in kitchens.

Tip: Ensure that your establishment is equipped with Wet Chemical Fire Extinguishers wherever deep frying equipment is present.

  2. Aim at the Base of the Fire: Position the nozzle so that you are targeting the flames directly.
  3. Squeeze the Handle: This releases the extinguishing agent onto the fire.
