Why should oily substances not be used with medical gas tanks?

Using oily substances with medical gas tanks is particularly dangerous because they can react with the gases contained in the tanks. Many medical gases, such as oxygen, can support and enhance combustion. If an oily substance is present, the risk of fire or explosion is significantly heightened. This is due to the fact that oxygen and other reactive gases can ignite oil-based substances, leading to hazardous situations that can result in serious injuries or even fatalities.

The safety protocols surrounding medical gases emphasize keeping these substances free from contaminants, such as oils or greases, to prevent chemical reactions that could occur under high pressure or when the gas is released. Ensuring that tanks and their associated equipment are clean and free from such materials is crucial to maintaining safety standards in medical environments.
