Water Fire Extinguishers are good for tackling fires involving burning paper, wood and soft furnishing (Class A fires), as the water soaks into the materials and cools them, while extinguishing the fire. This type of extinguisher does not contain harmful chemicals but has a low fire fighting rating. Due to this water fire extinguishers are usually large and heavy to overcome their lack in fire fighting power. It is also important to remember that water is an electrolyte and conducts electricity. Care must therefore be taken with regards to accidental use on exposed power cables. However, both the weight and the conductivity problems can be overcome by using water extinguishers with environmentally friendly additives. Water extinguishers with additives have a higher fire fighting rating which, therefore, allows the use of smaller and lighter extinguishers. Neither do they conduct electricity. As they are mostly free of harmful substances, water fire extinguishers are especially suitable in households where children have access to the extinguishers and an accidental discharge is possible.
