How far away must oxygen cylinders and fittings be kept from oil or greasy material?

Oxygen cylinders and fittings must be kept at least 20 feet away from oil or greasy materials due to the highly reactive nature of oxygen. When oxygen is present, it can dramatically accelerate the combustion of flammable materials. Even the smallest amount of oil or grease can pose a significant risk when in proximity to an oxygen source, as these substances can ignite and cause serious accidents or fires.

The 20-foot distance serves as a safety measure to minimize the risk of oxygen reacting with oil or grease and thereby enhances safety protocols in environments involving oxygen cylinders. This precaution is part of standard safety guidelines outlined by various health and safety organizations, emphasizing the importance of maintaining a safe distance to prevent potential hazards in any setting that handles oxygen.
