Why should clients on long-term oxygen avoid petroleum-based ointments?

• A. Because petroleum is flammable in enriched oxygen environments.
• B. Because it causes odor.
• C. Because it dries out skin.
• D. Because it interferes with oxygen delivery.

Answer: (A)

In long-term oxygen therapy, the biggest safety concern is fire risk. Oxygen-rich environments dramatically increase how easily something can ignite and how rapidly a fire can spread. Petroleum-based ointments are highly flammable, so applying them to the skin where oxygen is being delivered creates a combustible mixture. Even a small spark or heat source can ignite these products, posing a serious hazard. That’s why nonflammable alternatives, such as water-based lubricants or products specifically approved for use with oxygen therapy, are recommended. The other factors listed—odor, skin drying, or interference with oxygen delivery—don’t address the primary risk in this context, which is the potential for ignition.
