In which condition should CO2 fire extinguishers not be stored?

CO2 fire extinguishers should not be stored above 50 degrees Celsius because extreme heat can pose significant risks to the integrity and functionality of the extinguisher. At high temperatures, the pressure within the cylinder can increase significantly, potentially leading to a rupture or explosion. The CO2 inside the extinguisher is stored in a liquid state under pressure, and excessive heat can cause it to expand and raise the pressure to dangerous levels.

Storing CO2 extinguishers in a controlled environment, ideally below this temperature threshold, ensures that they remain safe and functional when needed. It is crucial to adhere to these guidelines for safety and to ensure that extinguishers operate effectively during an emergency.
