to the cylinder valve is acceptable, provided it is non-locking and can be opened without the
use of tools.
If you build an enclosure for an LP gas cylinder, follow these recommended specifications
and follow local codes.
Enclosures for LP gas supply cylinders need to be ventilated by openings at the level of the
cylinder valve and at floor level. This is accomplished by:
1) Having one side of the enclosure shall be completely open,
2) Having at least two ventilation openings at cylinder valve level in the side wall, equally
There shall be a minimum clearance of 2 inches (40.8mm) between the lower surface of the
floor and the LP gas supply cylinder enclosure and the ground.

sized, spaced at 180 degrees (3.14 rad), and unobstructed. Make sure each opening has
a total free area of not less then ½ square inch per pound (3.2 sq. cm/kg) of stored fuel
capacity and not less then a total free area of 10 square inches (64.5 sq. cm).
Ventilation openings need to be provided at floor level with a total free area of ½ inch
per pound (3.2 sq. cm/k) of stored fuel capacity and not less than a total free area of 10
square inches if the ventilation openings at floor level are in a side wall, make sure there
are at least two openings. The bottom of the openings shall be at floor level and the upper
edge no more than 5 inches (127 mm) above the floor. The openings need to be equally
sized, spaced at 180 degrees (3014 rad) and unobstructed.
Make sure every opening has minimum dimensions to permit the entrance of a 1/8 inch
(3.2mm) diameter rod.
