ACS element text (the applicant demonstrates understanding of)

Combustion hazards in an oxygen-rich environment.

Bottom line

Pilots should be aware of the increased danger of fire when using oxygen. Oils and greases may catch fire if exposed to oxygen, and therefore cannot be used for sealing the valves and fittings of oxygen equipment. Smoking during the use of any kind of oxygen equipment must also be strictly forbidden.
