Water fire extinguishers are a simple, effective solution for tackling Class A fires involving solid combustible materials such as wood, paper, textiles and cardboard. They work by cooling the burning material below its ignition temperature, helping to prevent re-ignition.
Why it works: water absorbs heat extremely efficiently, rapidly reducing fire temperature and stopping the combustion process at its source.
✅ Key benefits
- Highly effective on Class A fires
- Simple and intuitive to use
- No toxic gases released during discharge
- Cost-effective solution for low-risk environments
🏫 Best for
Schools, offices, shops, warehouses and other environments where the primary fire risk involves ordinary combustible materials rather than liquids or electrical equipment.
⚠️ Important considerations
Standard water extinguishers are not suitable for electrical fires and may contain additives to improve performance. Where electrical equipment is present or a more versatile solution is required, alternative water-based technologies are often preferred.
💡 Considering alternatives
In many modern indoor environments, enhanced water-based extinguishers offer greater flexibility and cleaner performance:
- Water mist extinguishers — suitable for multiple fire classes and safe for use around electrical equipment
- Water extinguishers with additives — enhanced performance on Class A fires using chemical additives
