In nitrogen servicing operations, non-involved personnel must maintain a minimum distance from the servicing point. How far?

• A. 10 feet
• B. 30 feet
• C. 50 feet
• D. 20 feet

Answer: (D)

When handling nitrogen servicing, the risk comes from a high-velocity gas jet and the possibility of cold or freezing effects from the gas. To protect anyone not involved in the operation, a safe-distance rule is used so that personnel aren’t in the path of the vent or exposed to a sudden release. The minimum distance required is 20 feet. This distance provides enough clearance so that a leaking or venting line won’t strike or injure a person, and it helps prevent exposure to the cold gas or any potential pressure surge. Keeping everyone at least 20 feet away minimizes the chance of injury if something momentarily releases or vents. Other distances are either too close to be safe or more conservative than necessary for typical nitrogen servicing duties.
