OSHA PROGRAM DIRECTIVE #100-61 STD 1-5.8 OCT 30, 1978

TO: REGIONAL ADMINISTRATORS/OSHA

Subject: 29 CFR 1910.104(b)(3)(iii), Oxygen; Bulk Oxygen Systems; Distance Between Systems and Exposures; Fire Resistive Structures

1. Purpose

To establish guidelines on citing a violation of 29 CFR 1910.104 (b)(3)(iii).

2. Directives Affected

None.

3. Background

a. Inquiries from various sources have been received regarding OSHA enforcement of 29 CFR 1910.104(b)(3)(iii) which prescribes the following minimum distance between any bulk oxygen storage container and fire resistive structure;
Fire resistive structures twenty-five feet from any structure with fire resistive exterior walls or sprinklered buildings of other construction, but not less than one-half the height of adjacent side wall of the structure.
    b.  These inquiries have noted that the source standard for 29 CFR
         1910.104(b)(3)(iii) was National Fire Protection Association
         (NFPA) No. 566-1965, Standard for the Installation of Bulk Oxygen
         Systems.  This was redesignated at NFPA No. 50, paragraph 5-1-2,
         with the 1971 edition, which states:
Not less than one foot (or other distance to permit system maintenance) from buildings or other than wood frame construction, including fire resistive, heavy timber, noncombustible, and ordinary construction.
