OXIDIZER GASES—DISTANCE FROM STORAGE TO EXPOSURESa
|QUANTITY OF GAS STORED (cubic feet at NTP)||DISTANCE TO A BUILDING NOT ASSOCIATED WITH THE MANUFACTURE OR DISTRIBUTION OF OXIDIZING GASES OR PUBLIC WAY OR LOT LINE THAT CAN BE BUILT UPON (feet)||DISTANCE BETWEEN STORAGE AREAS (feet)|
|0 — 50,000||5||5|
|50,001 — 100,000||10||10|
|100,001 or greater||15||10|
For SI: 1 foot = 304.8 mm, 1 cubic foot = 0.02832 m3.
- The minimum required distances shall not apply where fire barriers without openings or penetrations having a minimum fire-resistance rating of 2 hours interrupt the line of sight between the storage and the exposure. The configuration of the fire barrier shall be designed to allow natural ventilation to prevent the accumulation of hazardous gas concentrations.
