This article shall apply to all storage and handling of liquefied petroleum gas and the installation of all equipment pertinent to systems for such uses.
A. 
A permit shall be obtained for each installation of liquefied petroleum gas employing a container or an aggregate of interconnected containers of over 2,000 gallons water capacity and for each permanent installation, irrespective of size of containers, made at buildings in which people congregate for civic, political, educational, religious, social or recreational purposes. Such buildings shall include schools, churches, hospitals, institutions, hotels and restaurants, each having a capacity of 20 or more persons.

Within the limits established by law restricting the bulk storage of liquefied petroleum gas for the protection of heavily populated or congested commercial areas, the aggregate capacity of any one installation shall not exceed 2,000 gallons water capacity; except that in particular installations this capacity limit may be altered at the discretion of the Chief of the Fire Department after consideration of special features such as topographical conditions, nature of occupancy and proximity to buildings, capacity of proposed tanks, degree of private fire protection to be provided and facilities of the local Fire Department.
A. 
Gas for fuel purposes in either the liquid or vapor phase shall not be piped into any building at pressures in excess of 20 psig except as follows:
(1) 
Buildings used exclusively to house equipment for vaporization, pressure reduction, gas mixing or gas manufacturing or distribution;
(2) 
Buildings, or portions of buildings, separated from other portions by walls, partitions and floor and ceiling assemblies of noncombustible material having a fire resistance rating of not less than two hours, used exclusively to house internal combustion engines or industrial processes;

Portable containers shall not be taken into buildings except as provided in § 198-82.
Containers and first stage regulating equipment shall be located outside of buildings other than buildings especially provided for this purpose, except that containers and regulating equipment may be used indoors under the following conditions:

In industrial applications where oxygen is not required;
D. 
In use as a motor fuel; or
E. 
In storage awaiting use or resale.
