Dear Mr. Larson:
This is in response to your letter dated October 10, 1978, requesting a clarification of 29 CFR 1910.104(b)(3)(iii) and (iv).
29 CFR 1910.104(b)(3)(iii) of the General Industry Safety and Health Standards applys if the bulk oxygen storage system is located above ground and out of doors.
29 CFR 1910.104(b)(3)(iv) of the General Industry Safety and Health Standards applys if the bulk oxygen storage system is located or installed in a building of fire resistive construction at least 10 feet from any opening in adjacent walls. Spacing from such structure shall be adequate to permit maintenance, but shall not be less than 1 foot.
If I can be of any further assistance, please feel free to contact me.
Sincerely,
