Water Fire Extinguisher

Water fire extinguishers are still one of the most used fire extinguisher type.

Water fire extinguisher uses:

• Fires involving flammable solids, such as paper, wood, and textiles (‘class A’ fires)

Do not use water fire extinguishers for:

• Electrical fires – this would be highly dangerous and could result in electrocution
• Fires involving flammable liquids, such as petrol and paint (‘class B fires)
• Fires involving flammable gases, such as methane and butane (‘class C fires)
• Cooking fires involving oil and grease (‘class F fires)

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.
