Simple water-based fire extinguisher: As clean water is used and environmentally friendly water-based extinguishing agent is added, it is non-toxic, odourless and free of dust and other residues when extinguishing the fire, which does not cause secondary pollution to the environment and does not deplete the ozone layer in the atmosphere. The fire extinguisher has an internal pressure indicator and a pressure filling mechanism, which makes it easy to service. This type of extinguisher can be used to put out Class A fires such as wood, bamboo, cotton fabric, paper etc., Class B fires such as petrol, paraffin, vegetable oil, grease etc. and Class F fires such as all types of vegetable oil. However, it is not used to fight gas and light metal fires and is widely used in homes and vehicles.
