| FYI | Bulk oxygen storage systems shall be located aboveground out of doors, or shall be installed in a building of fire-resistive or noncombustible construction, adequately vented, and used for that purpose exclusively. The location shall be such that containers an associated equipment shall not be beneath or exposed by failure of electric power lines, piping containing all classes of flammable or combustible liquids or piping containing flammable gas.
The basis for the Oxygen system related plan review comments is NFPA-55, Chapter 9, 2005 Edition.
THE SYSTEM IS REQUIRED TO COMPLY WITH NFPA 55, TABLE 9.3.2 "MINIMUM SEPARATION DISTANCES BETWEEN BULK LIQUID OXGYEN SYSTEMS AND EXPOSURE HAZARDS"
ATTENTION: THE LOCATION AND FOUNDATION APPEAR TO BE COMPLIANT SUBJECT TO CORRECTION OF DISAPROVED COMMENTS BELOW. |
