How shall gauges, regulators, and valves on oxygen and acetylene tanks be maintained?

• A. Kept clean, and free of oil and grease
• B. Kept wet with water
• C. Painted red
• D. Lubricated with oil

Answer: (A)

Safety around oxygen and acetylene equipment hinges on keeping all gauges, regulators, and valves clean and free of oil and grease. Oxygen is a strong oxidizer, and any oil or grease on a regulator, valve stem, or fittings can ignite or cause an explosion when exposed to oxygen flow. A tiny film of oil can act as fuel in the presence of oxygen, so cleanliness isn’t just about preventing leaks or aiming for accurate readings—it’s a critical fire-protection measure. Regularly cleaning these components with approved, non-ooil cleaners and wiping them dry helps ensure they seal properly, read accurate pressures, and operate safely. Oils or lubricants should never be used on oxygen or acetylene equipment. Wetting with water is not an appropriate method for maintenance, and painting or lubricating with oil introduces hazards rather than reducing them. If contamination is suspected, remove the equipment from service and have it cleaned or serviced by qualified personnel.
