You should never allow smoking around an oxygen cylinder. True or False?

• A. Not Applicable
• B. Sometimes
• C. True
• D. False

Answer: (C)

Oxygen-rich environments dramatically increase the risk that a flame will ignite and spread. A cigarette is a strong ignition source and leaves embers and flammable residues that can easily ignite nearby fuels such as clothing, bedding, or liniments. When oxygen is present, materials burn more readily and burn hotter and faster, so a small spark or ember around an oxygen cylinder can lead to a rapid, dangerous fire. Because of this, the safe rule is to never allow smoking around an oxygen cylinder. This isn’t a situation where “sometimes” or “false” would apply—smoking near oxygen is inherently unsafe. Always ensure no ignition sources are present in areas with oxygen access and follow the proper safety protocols.
