Fire extinguishers are portable firefighting equipment used to suppress or extinguish small fires. They come in different sizes and types, each designed to extinguish fires caused by different types of materials. In Australia, fire extinguishers are used in a wide range of settings, including commercial buildings, industrial facilities, residential properties, and public spaces. They are an essential component of a building's fire protection system and can help prevent the loss of life and property in the event of a fire.
