Why must emergency oxygen be stored away from heat, spark, flame, and explosive environments?

Emergency oxygen must be stored away from heat, spark, flame, and explosive environments because it is a compressed gas that supports combustion. Oxygen itself is not flammable, but it enhances the burning of other materials. When oxygen is present in higher concentrations, even materials that are typically not combustible can ignite more easily and burn more intensely. This is crucial for ensuring safety, as improper storage in environments where there are sources of ignition can lead to fires or explosions, especially if oxygen leaks into the surrounding atmosphere. Thus, maintaining proper storage conditions is essential for preventing hazardous situations and ensuring the safety of everyone involved.
