What might happen if a fire extinguisher is improperly stored?

Improper storage of a fire extinguisher can lead to a situation where it becomes ineffective when needed most. Fire extinguishers are designed to work optimally under certain conditions, including proper temperature ranges and levels of accessibility. If they are stored in environments that are too hot, too cold, or in locations where they can be knocked over or damaged, their internal mechanisms can fail or the extinguishing agent may settle or degrade.

For instance, if a fire extinguisher is placed in a location exposed to extreme temperatures, such as a garage or an uninsulated shed during winter, the materials inside may freeze, which impedes the extinguisher's functionality. In addition, placing it in areas where it can be obstructed makes it less available during an emergency. Therefore, ensuring that a fire extinguisher is stored correctly—such as in a controlled climate, upright, and easily accessible—is crucial to maintaining its readiness for use in case of a fire.
