Why should safety precautions similar to those taken during aircraft refueling be applied when servicing the oxygen system?

The application of safety precautions similar to those taken during aircraft refueling when servicing the oxygen system is primarily due to the fact that oxygen supports combustion, which can occur violently. Oxygen is a highly reactive gas that enhances the flammability of materials; therefore, when handling or servicing systems that contain oxygen, it is crucial to be aware that even minor sparks or contact with combustible materials can lead to intense fires or explosions.

This need for caution is amplified in environments where there may be flammable materials, including oils, greases, or other hydrocarbon products that might come into contact with the oxygen. As a result, strict protocols are established to prevent such interactions, ensuring that any servicing of the oxygen system is carried out safely and with appropriate measures to mitigate fire hazards.
