Q: Are oxygen cylinder tanks (in holders) allowed to be stored in alcoves in corridors? Also, what about clean linen carts? I am told that our accreditation organization allows this, but I don’t know if CMS does.
A: Oxygen cylinders are permitted to be stored outside of a designated room, provided they are properly secured; they do not infringe upon the required corridor width; and the aggregate total of cubic feet of medical gas in cylinders (all gas, not just oxidizing gas) does not exceed 300 cubic feet per smoke compartment. So, a couple E size cylinders in holders, stored in an alcove sounds acceptable to me.
Under normal conditions, the presence of combustibles, such as paper, cardboard, plastics, and clean linen are not considered to be hazardous until the area in which they are contained exceeds 50 square feet. A clean linen cart in an alcove that does not exceed 50 square feet appears to not meet the requirements of a hazardous area (see 18.104.22.168), and therefore does not have to be contained in a room designated as a hazardous room. However, some accreditation organizations may take a different look at this, and consider the volume of a 6 foot tall, by 4 foot wide, by 2½ foot deep clean linen cart to be sufficient capacity of combustibles to be a significant threat, even though it does not meet the LSC definition of a hazardous area. I know that at least one accreditation organization requires the corridor and alcove to be sprinklered in order to store a clean linen cart there.
