2. Ensure the mask attached is for therapeutic use only

3. Verify that the gauge reads 3/4 to full

4. Only check the presence of the carry strap

The correct answer is: Verify that the gauge reads 3/4 to full

A key precaution when operating a portable oxygen bottle is to verify that the gauge reads 3/4 to full. This ensures that there is an adequate supply of oxygen available for use, allowing for effective response in situations where oxygen is needed, such as in emergencies or for passengers who may require supplemental oxygen. Monitoring the gauge is crucial, as operating with a low level of oxygen can compromise safety and well-being. Ensuring the oxygen bottle is well-stocked aligns with standard safety protocols and helps in maintaining readiness for any situation where supplemental oxygen might be necessary, thereby protecting both staff and passengers during flight operations.
