Which of the following is a common safety feature found in barracks?

Fire extinguishers are a common safety feature in barracks because they are critical for preventing and controlling fires, which can pose significant risks in communal living environments. Given the nature of barracks, where many individuals live in close quarters, the risk of fires can increase due to shared cooking facilities, electrical equipment, and other potential hazards. Therefore, having accessible fire extinguishers can help ensure a quick response to a fire emergency, potentially saving lives and minimizing damage.

While first aid kits, emergency exits, and security guards are also important safety features in various settings, fire extinguishers are specifically designed to address one of the most immediate threats in such environments. First aid kits provide medical assistance in emergencies, emergency exits facilitate safe evacuation, and security guards ensure the overall safety of the premises, but fire extinguishers are directly associated with mitigating fire risks, making them a crucial element in barrack safety protocols.
