6303.4 Multiple class storage.

Except as otherwise specifically provided in this code, where more than one class of oxidizer is stored in the same control area, the maximum quantity allowed of each oxidizer shall be limited as follows: the maximum quantity shall be reduced by multiplying the maximum allowable quantity for each such material by the proportional amount that such material bears to the total quantity of oxidizer stored in the control area. The total of the proportional amounts shall not exceed 100 percent.

6303.5 Filling of portable containers.

Portable containers of oxidizing gases shall be filled at a compressed gas dispensing facility, except that:

   1.   liquid oxygen home care containers alternatively may be filled outdoors from a cargo tank designed to supply such containers. When a liquid oxygen home care container is filled from a cargo tank on an asphalt or combustible surface, a drip pan compatible with liquid oxygen shall be provided under home care container fill and vent connections during the filling process to minimize the risk of ignition of the combustible surface; and

   2.   liquid oxygen ambulatory containers alternatively may be filled in the residence or residential health care setting from the liquid oxygen home care container designed for such purpose, in accordance with the manufacturer's instructions.

6303.5.1 Smoking prohibited.

Smoking shall be prohibited in rooms or areas where liquid oxygen containers are filled.

	greater than 5,000 up to 10,000	400
	over 10,000	As required by the commissioner

 

For SI: 1 foot = 304.8 mm, 1 pound = 0.454 kg.

a.   Any quantity over the amount required for detached storage in accordance with FC 5003.8.2, or over the outdoor maximum allowable quantity for outdoor control areas.

6304.1.3 Explosion control.

Any room or other area in which Class 4 liquid or solid oxidizers are stored shall be provided with explosion control in accordance with FC 911 and the construction codes, including the Building Code.
