Which type of oxygen system location is generally prohibited from having access to open flame areas?

The indoor oxygen system location is generally prohibited from having access to open flame areas due to safety concerns. Oxygen is a highly reactive gas that greatly supports combustion. In an indoor setting, the presence of open flames—for example, from candles, stoves, or heating equipment—poses a significant risk of fire or explosion in the event of an oxygen leak.

By having strict regulations against open flames in areas where oxygen is stored or used, the likelihood of igniting a fire due to accidental exposure to elevated oxygen levels is minimized. These safety measures are critical in healthcare facilities where medical gases are utilized, ensuring the protection of patients and staff who may be in close proximity to oxygen sources.

Other oxygen system locations, such as outdoor areas, central supply, and cryogenic systems, may have different regulations or be better suited to manage risks associated with open flames in a manner that does not compromise safety. However, the indoor environment presents unique challenges that justify stringent restrictions against the use of open flames. This is why the indoor oxygen system location is specifically designated as being off-limits to such hazards.
