How many people are required to service the aircraft with gaseous oxygen?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

Gaseous oxygen servicing is a safety-critical task, because oxygen enhances combustion and even small contaminants can cause fires or explosions. Because of that, two trained people are required to perform the operation. One person operates and monitors the servicing equipment, ensures proper connections and flow, and handles the filling process. The second person serves as a safety observer, ensuring cleanliness by preventing oil, grease, or other hydrocarbons from entering the oxygen system, watching for leaks, and confirming that all safety steps are followed. Having two people allows immediate action if anything goes wrong, such as a leak or contamination. That’s why the correct approach is to have two people involved.
