Figure 1: STORAGE OF COMPRESSED GASES OUTDOORS These distances do not apply where protective structures having fire resistance rating of two (2) hours interrupt the line-of-sight between un-insulated portions of the bulk oxygen storage installation and the exposure. The protective structures protect un-insulated oxygen storage containers or supports, control equipment, and system piping (or parts thereof) from external fire exposure. Liquid oxygen storage containers are insulated. Such containers may provide line- of-sight protection for un-insulated system components. Interruption of the line-of-sight means that an “eye” on any part of the un-insulated portion of the bulk oxygen storage installation cannot “see” any part of the exposure. 301
