What happens if oil or grease is used on or near the emergency oxygen system?

Using oil or grease near the emergency oxygen system creates a significant fire hazard. Oxygen is not flammable by itself; however, it supports combustion, and when combined with flammable substances like oil or grease, it can lead to a highly volatile environment. The introduction of these substances increases the risk of an explosive reaction, especially if there is a spark or heat source present. This is why safety protocols explicitly advise against using any lubricants or flammable materials in the vicinity of oxygen systems. Ensuring the integrity and safety of the oxygen system is crucial for effective emergency response and preventing accidents.
