Section 19.15.40.22 - LP GAS INSTALLATIONS AT SPECIAL EVENTS

A. Containers: All containers must be located outside the booth, the building, or the enclosure. All containers must be secured in a position (usually in an upright position) so that vapor only will be present at the vapor service valve. The secured container's device, such as a chain, must be able to support the weight of the container plus the container's contents. All containers must be approved LP gas container. Any DOT cylinder for LP gas must be marked with the re-qualification date(s) if the container is more than twelve years old. All containers must be leak-free. Any LP gas container showing excessive rust, corrosion, pitting, or denting shall not be used. The bottom of each container shall be checked for these conditions. All portable DOT cylinders must have a fixed "warning" label that includes information on the potential hazards of LP gas. Outlets for all unused containers shall be capped or plugged. The vapor service valve must be sealed when the container is not in use. (Example: A p.o.l. plug installed in the open vapor outlet.) A quick-closing coupling approved for use on LP gas containers may be used in lieu of the sealing cap or plug. When a container's water capacity is greater than 239 pounds (nominal 100 lb.) An LP gas permit must be obtained before using such container.

B. Hoses: The only hoses that shall be used are those approved for use with LP gas. The hose end couplings must be installed as recommended by the hose manufacturer. (Unacceptable: an automotive screw-type clamp installed on the end of the hose.) All hoses must be leak-free. All hoses must be kept out of the way of foot and vehicular traffic.

C. Appliances: All appliances used in food booths must have an accessible shut-off valve near the appliance that can be easily closed in case of an emergency. Only appliances that are leak-free and approved for the use of LP gas shall be used.

D. Filling of containers: The filling of LP gas containers on site shall be done in a designated area separated from the general public or at times when the visitation of the general public is minimal. Nylon jackets, cigarette lighters, strikers, and/or matches are not allowed in the filling area.

E. Leak test: A leak test shall be performed each day before the food booth is opened for business, any time a cylinder is exchanged, and any time the LP gas system is modified. Soap (without ammonia) mixed with water or a combustion gas hand-held electronic leak detector can be used for detection of leaks. The entire system must be free of leaks.
