Fire extinguisher serves as a handheld, active means of addressing small fires by employing dry or wet chemical agents to control or extinguish them in emergency situations. However, its utility is limited; it's not designed for tackling fires that have escalated beyond control, reached ceilings, or present imminent dangers to users, such as restricted escape routes, smoke hazards, or potential explosions. Typically, these extinguishers feature a cylindrical

pressure vessel containing the extinguishing agent, although variations with non-cylindrical vessels exist.
