Water fire extinguishers with additives are designed to enhance the performance of standard water units on Class A fires. By incorporating chemical additives, they improve wetting and penetration, allowing water to cool burning materials more effectively.
Why it works: additives reduce surface tension, helping water
soak deeper into burning materials and improving knock-down and cooling performance.
✅ Key benefits
- Enhanced Class A performance compared to standard water
- Improved penetration into porous materials
- Cost-effective upgrade over plain water extinguishers
- Familiar operation for users trained on water units
🏫 Best for
Offices, schools, retail spaces, warehouses and other environments where Class A fire risks dominate but improved performance over standard water is desired.
⚠️ Important considerations
Water extinguishers with additives are not suitable for live electrical fires and still rely on chemical agents. Disposal requirements and environmental considerations should be reviewed, particularly where sustainability is a priority.
💡 Considering alternatives
For broader protection or cleaner discharge in mixed-risk environments, alternative water-based technologies may be more appropriate:
- Water mist extinguishers — multi-risk coverage and safe for use around electrical equipment
- Standard water extinguishers — simple, chemical-free option for Class A fire risks
