What condition should be avoided when storing an emergency oxygen system?

When storing an emergency oxygen system, it is crucial to avoid extreme temperatures because they can negatively impact the integrity and functionality of the oxygen equipment. Temperature fluctuations can affect the pressure inside the oxygen tank and potentially lead to a reduced lifespan or malfunction of the system. Additionally, storing oxygen in environments with extreme heat can lead to increased pressure, which poses a safety risk. On the other hand, while high humidity, direct sunlight, and severe weather conditions can also be concerns for storage, extreme temperatures has a more direct and significant impact on the chemical and physical properties of the contents of the oxygen system. Proper storage conditions ensure that the emergency oxygen system remains effective and safe to use when needed.
