How water extinguishers work:
Water has an extreme cooling effect.
When it is directed at flames, it lowers the overall temperature, making it impossible for the fire to burn.
Pros and Cons of water fire extinguishers:
Pros: highly cooling and so puts fires out rapidly; no negative environmental impact.
Cons: only works on one class of fire; dangerous if the water comes into contact with electrical equipment.
Who needs water fire extinguishers?:
Whilst water fire extinguishers are the ‘original’ extinguisher, these days it is quite common to recommend foam extinguishers instead, as foam extinguishers tackle both class A and class B fires.
However, environments which store large quantities of combustible materials may benefit from having water fire extinguishers. Examples include:
• Warehouses
• Storage units
• Paper mills
• Textile factories
Water fire extinguishers are also well suited for domestic use, especially in living rooms and bedrooms. They are best paired with a CO2 extinguisher, so that electrical fire risk is also covered.
