§ 30-103. Portable cylinders and containers.

A. 

Portable vapor withdrawal cylinders with water capacities greater than 2 1/2 pounds which are or will be owned by the user or intended user are not to be filled or refilled unless the cylinder has been properly tested or requalified in accordance with United States Department of Transportation regulations and has attached thereto a warning label approved by the Chief Fire Marshal. Cylinder(s) shall not be released to the owner or his representative by the seller or refiller until it has been determined that the cylinder has not been filled beyond acceptable limits (42% of its water weight capacity), is free of leaks and is safe for use or continued use.

B. 

Containers, except those use in liquid withdrawal service up to and including 40 pounds' propane capacity, shall be checked for leaks immediately after filling. The test will be done by a qualified person who has a certificate of fitness by checking each connection with a soap-water solution or by total submersion in a water-filled container. Should a leak exist, the container shall be emptied immediately and marked with paint or indelible marker or other suitable means to positively identify a container that leaks. A leaking container shall not be transported from the filling site while it contains any product, either liquefied or vapor.

C. 

All portable Department of Transportation and Interstate Commerce Commission containers shall have the date of manufacture permanently stamped on the collar; if permanently attached, on the cylinder; and, in the case of containers more than 12 years old, shall have the date of the most recent inspection, month/year, marked on the collar or cylinder.

D. 

Every person, firm or corporation offering filled liquefied petroleum gas cylinders for sale or resale shall have a certified scale on the premises to ensure that each portable cylinder containing liquefied petroleum gas has not been filled beyond its safe capacity. Each such cylinder shall be weighed before delivery to the purchaser to ensure that the cylinder is not filled beyond acceptable limits.

E. 

Container storage forbidden.

(1) 

No container of liquefied petroleum gas, either in use or in storage, will be permitted inside or on the roof or balcony of any occupied building or in or on any construction attached to an occupied building, except as permitted in Subsections F and G below.

(2) 

Industrial lift trucks will comply with the provisions of the appropriate standards of the NFPA.

(3) 

Storage of containers must be outside the building, at least 25 feet from any building. Storage is to be in either a noncombustible top and bottom vented structure or surrounded by a substantial metal fence enclosure, such enclosure to be adequately secured against access by unauthorized persons.

F. 

Department of Transportation specification cylinders with a maximum water capacity of 2 1/2 pounds, used with completely self-contained hand torches and similar applications, may be stored or displayed in a building frequented by the public. The quantity of liquefied petroleum gas shall not exceed 200 pounds.

G. 

Temporary or emergency use of liquefied petroleum gas equipment in occupied or unoccupied buildings shall be approved by the Chief Fire Marshal prior to use. Any tank used inside any building shall be equipped with an excess flow valve to shut off the flow of gas if a hose or connector is severed.
