Current through Register 2025 Notice Reg. No. 2, January 10, 2025
Section 4516.1 - LPG - Location and Installation of Containers and Systems(a) No LP-gas container shall be installed or provision made for installing or storing, even temporarily, inside any commercial modular, except for listed, completely self-contained hand torches, lanterns, or similar equipment with containers having a maximum water capacity of not more than two and one-half (2 1/2) pounds (approximately one (1) pound LPG capacity).(b) Where provided, containers, control valves and regulating equipment shall be mounted on the hitch, installed in a single compartment that is vapor-tight to the inside of the commercial modular and accessible only from the outside, or mounted on the frame. Compartments shall be constructed of galvanized steel, not less than 0.0299 inch (0.759 mm) thick. Seams and joints shall be lapped, mechanically secured and made airtight to the interior. Alternate materials and methods of construction may be used if they provide equivalent quality, strength, effectiveness, fire resistance, durability and safety. Fuel-gas tubing from the gas-supply connection may pass through the wall, floor or ceiling of the compartment. Where such tubing passes through any wall, floor or ceiling, such tubing shall be protected by the use of bulkhead fittings or equivalent devices which shall snugly fit both the tubing and the hole in the compartment through which the tubing passes.(c) Containers and container carriers shall be securely mounted, located, and installed, so as to minimize the possibility of damage to containers, their appurtenances or contents as follows: (1) Containers shall be installed with as much road clearance as practicable but not less than the minimum road clearance under maximum spring deflection. This clearance shall be measured to the bottom of the container, or to the lowest fitting, support or attachment on the container or container housing, whichever is lower.(2) Fuel containers and container carriers shall be securely mounted to prevent jarring-loose, slipping or rotating, and fastenings shall be designed and constructed to withstand, without permanent visible deformation, static loading in any direction equal to four times the weight of the container filled with fuel. When containers are mounted within a commercial modular, the securing of the container to the unit shall comply with this provision. Any hoods, domes or removable portions of the housing or cabinet shall be provided with means to keep them firmly in place in transit.(3) All container valves, appurtenances and connections shall be adequately protected to prevent damage due to accidental contacts with stationary objects, from loose objects, stones, mud, or ice, thrown up from the ground or floor, and from damage due to overturn of the commercial modular or similar accident. In the case of permanently mounted containers, this provision may be met by the location on the commercial modular, with parts of the commercial modular furnishing the protection. On portable (removable) containers the protection for container valves and connections shall be permanently attached to the container.(d) Access to a compartment containing LP gas tanks or cylinders shall be by a door or opening in the exterior wall of the commercial modular. Access doors or panels of compartments shall not be equipped with locks or require special tools or knowledge to open. The compartment shall be ventilated with two vents having an aggregate area of not less than two percent (2%) of the floor area of the compartment and shall open unrestricted to the outside atmosphere. The required vents shall be equally distributed between the floor and ceiling of the compartment. If the bottom vent is located in the access door or wall, it shall be flush with the floor level of the compartment. The top vent shall be located in the access door or wall with the bottom of the vent not more than twelve (12) inches below the ceiling level of the compartment. All vents shall have an unrestricted discharge to the outside atmosphere.Cal. Code Regs. Tit. 25, § 4516.1
