What is the ideal temperature range for storing fire extinguishers?

The ideal temperature range for storing fire extinguishers is between 32°F and 120°F. This range ensures that the extinguishers remain effective and functional. The minimum temperature of 32°F is critical to prevent the contents from freezing, which could render the extinguisher inoperable when needed. On the upper end, 120°F is the threshold where the risk of the extinguisher's components degrading or the pressure inside the canister becoming unsafe increases. It is essential for fire extinguishers to be stored in environments that avoid extreme temperatures to maintain their reliability during emergencies.
