Water mist extinguishers are multi-class rated, making them ideal for environments where different fire risks exist:
- Class A – Solid combustibles such as wood, paper, textiles
- Class B – Flammable liquids such as oils and fuels
- Class C – Safe around gas fires (though not always the first choice for suppression)
- Electrical Fires – Tested up to 35kV, safe for use on live electrical equipment
