Oxygen-enriched air near a cannula raises fire risk near open flames or vaping/smoking
Because oxygen-enriched air significantly lowers ignition thresholds and accelerates combustion, anesthesia safety literature recommends keeping ignition sources at least 10cm from a nasal-cannula oxygen outlet at flow rates of 4 L/min or higher, a relevant fire-safety consideration for oxygen bars that may operate near candles, scented-oil diffusers, or permit nearby smoking or vaping.
Safety notes
Keep open flames, lit cigarettes/vapes, and other ignition sources well clear of the oxygen outlet and delivery tubing; avoid combining scented/aromatic additives delivered near an open flame with oxygen-enriched air.
