        using a safety factor of not less than four based on
        the ultimate strength of the material to be used.
           (4) LP-gas container valves and accessories. (i)
        Valves in the assembly of a two-cylinder system
        shall be arranged so that replacement of containers
        can be made without shutting off the flow of gas to
        the appliance(s). This provision is not to be
        construed as requiring an automatic change-over
        device.
           (ii) Shutoff valves on the containers shall be
        protected as follows, in transit, in storage, and
        while being moved into final utilization by setting
        into a recess of the container to prevent possibility
        of their being struck if container is dropped upon a
        flat surface, or by ventilated cap or collar, fastened
        to the container, capable of withstanding a blow
        from any direction equivalent to that of a 30-pound
        weight dropped 4 feet. Construction shall be such
        that the blow will not be transmitted to the valve.




                                                     53
