Which maintenance detail is stated for gauges, regulators, and valves on oxygen and acetylene tanks?

• A. Kept clean and free of oil and grease
• B. Kept dry and dusty
• C. Routinely painted orange
• D. Replaced weekly with new parts

Answer: (A)

Keeping gauges, regulators, and valves clean and free of oil and grease is essential when working with oxygen and acetylene. Oil and grease can ignite or explode in the presence of concentrated oxygen, and acetylene is particularly sensitive to contaminants. Even small amounts of oil can cause a flash or reaction inside regulators or fittings, leading to fires or equipment failure. Maintaining a clean, oil-free surface helps ensure accurate readings, prevents leaks, and reduces the risk of ignition during gas delivery. Dry and dusty conditions don’t address the ignition risk from oil or grease, and routine painting or weekly part replacement aren’t standard safety practices for these components.
