Container location.
LP-gas containers
shall be located with respect to buildings, public ways and lot lines of
adjoining property that can be built upon, in accordance with Table

a. Minimum distance for underground
LP-gas containers shall be measured from the pressure relief device and the
filling or liquid-level gauge vent connection at the container, except that all
parts of an underground LP-gas container shall be not less than 10 feet from a
building or lot line of adjoining property that can be built upon.
b. For other than installations in
which the overhanging structure is 50 feet or more above the relief-valve
discharge outlet. In applying the distance between buildings and ASME LP-gas
containers with a water capacity of 125 gallons or more, not less than 50
per cent of this horizontal distance shall also apply to all
portions of the building that project more than 5 feet from the building wall
and that are higher than the relief valve discharge outlet. This horizontal
distance shall be measured from a point determined by projecting the outside
edge of such overhanging structure vertically downward to grade or other level
upon which the LP-gas container is installed. Distances to the building wall
shall be not less than those prescribed in this table.
c. Where underground multicontainer
installations are comprised of individual LP-gas containers having a water
capacity of 125 gallons or more, such containers shall be installed so as to
provide access at their ends or sides to facilitate working with cranes or
hoists.
d. At a consumer site, if the aggregate
water capacity of a multicontainer installation, comprised of individual LP-gas
containers having a water capacity of less than 125 gallons, is 500 gallons or
more, the minimum distance shall comply with the appropriate portion of Table
6104.3of this rule, applying the aggregate capacity rather
than the capacity per LP-gas container. If more than one such installation is
made, each installation shall be separated from other installations by not less
than 25 feet. Minimum distances between LP-gas containers need not be
applied.
e. The following shall apply to
above-ground containers installed alongside buildings:
1. LP-gas containers of less than a
125-gallon water capacity are allowed next to the building they serve where in
compliance with items 2, 3 and 4.
2. Department of transportation (DOTn)
specification LP-gas containers shall be located and installed so that the
discharge from the container pressure relief device is not less than 3 feet
horizontally from building openings below the level of such discharge and shall
not be beneath buildings unless the space is well ventilated to the outside and
is not enclosed for more than 50 per cent of its perimeter.
The discharge from LP-gas container pressure relief devices shall be located
not less than 5 feet from exterior sources of ignition, openings into
direct-vent (sealed combustion system) appliances or mechanical ventilation air
intakes.
3. ASME LP-gas containers of less than
a 125-gallon water capacity shall be located and installed such that the
discharge from pressure relief devices shall not terminate in or beneath
buildings and shall be located not less than 5 feet horizontally from building
openings below the level of such discharge and not less than 5 feet from
exterior sources of ignition, openings into direct vent (sealed combustion
system) appliances or mechanical ventilation air intakes.
4. The filling connection and the vent
from liquid-level gauges on either DOTn or ASME LP-gas containers filled at the
point of installation shall not be less than 10 feet from exterior sources of
ignition, openings into direct vent (sealed combustion system) appliances or
mechanical ventilation air intakes.
f. This distance is allowed to be
reduced to not less than 10 feet for a single LP-gas container of 1,200-gallon
water capacity or less, provided such container is not less than 25 feet from
other LP-gas containers of more than 125-gallon water capacity.

6104.3.1
Installation on roof prohibited.
LP-gas
containers used in stationary installations shall not be located on the roofs
of buildings.
(b)
6104.3.2 Special hazards.
LP-gas containers shall be located with respect to
special hazards including, but not limited to, above-ground flammable or
combustible liquid tanks, oxygen or gaseous hydrogen containers, flooding or
electric power lines as specified in section 6.4.4 of NFPA 58 as listed
in rule
1301:7-7-80
of the Administrative Code.
