25.1447(c)(3) Equipment standards for oxygen-dispensing units
ED Decision 2017/015/R
It is acceptable that oxygen outlets/units of dispensing equipment are not provided within an area where people are likely to congregate (for instance a waiting area for lavatory facilities, a bar/lounge area etc.), provided the applicant demonstrates that sufficient oxygen-dispensing outlets are within five feet or five seconds reach of the area and that no visual obstruction exists between the potential oxygen users and the outlets, such as curtains or partitions, unless another method of indication (e.g. an ‘oxygen in use’ light) is provided in the area.
There should be at least two outlets and units of dispensing equipment in toilets, washrooms, galley work areas etc. In such areas where occupancy of more than two persons can be expected, the number of outlets (within the area or within five feet or five seconds reach) should be consistent with the expected maximum occupancy.
In the case of a shower, there should be an oxygen outlet and unit of dispensing equipment immediately available to each shower occupant without stepping outside the shower. Reaching through an opened shower cubicle door is acceptable, in which case the door should be sufficiently transparent so that the location of the mask and the required actions to access it are immediately obvious.

Oxygen dispensing units on large airplanes must be readily accessible. Outlets should be within five feet/seconds reach of congregation areas, unobstructed or indicated. Toilets/galleys require at least two outlets, scaled to occupancy. Showers need immediate access to oxygen without exiting, potentially through a transparent door.
