At what temperature range is it recommended to store fire extinguishers?

Storing fire extinguishers in the temperature range of 32°F to 120°F is recommended because this range ensures that the integrity and functionality of the extinguisher are maintained. Fire extinguishers contain pressurized substances, and extreme temperatures—both cold and hot—can affect the pressurization and chemical effectiveness within the extinguisher.

In colder temperatures, if the extinguisher drops below freezing, the contents may freeze or become less effective, while in excess heat, the pressure inside the canister can increase, potentially leading to a failure in the device. Therefore, maintaining the extinguisher within the recommended temperature range is crucial for ensuring it operates effectively when needed. This recommendation aligns with standards set by organizations that regulate fire safety equipment, promoting both reliability and safety.
