The responsibility for using a fire extinguisher primarily lies with individuals who are trained and competent to do so. Typically, the "responsible person" in a building or workplace—such as the employer, owner, occupier, or a designated fire warden or fire marshal—is accountable for ensuring fire safety measures are in place, including providing fire extinguishers and appropriate training for their use. While anyone can use a fire extinguisher as a last resort for escape (for example, to clear an exit route), actual use for firefighting should be performed only by those trained to use the extinguisher safely and effectively. Fire wardens or trained staff are often appointed to handle fire extinguishers in an emergency to control or extinguish small fires, but personal safety and the size/severity of the fire should always be considered before attempting to use one.
