✓�•� II 'ISrRIAL RELATIONS -"TYLE 8 (Register 77.y 144-2-77) (e) All stationary storage tanks exceeding 1,200 gallons capacity shall have the loading and unloading connections secured to a concrete bulkhead or equivalent designed to withstand a horizontal pull of not less than 2,040 pounds in any direction, unless other suitable protection is provided. This bulkhead shall not be located underneath the tank. The loading and unloading connections shall be firmly secured to this bulkhead and the piping between the bulkhead and tank shall be in- stalled in a manner to provide for expansion,contraction,jarring, vibra- tions, settling, etc. For skid tanks exceeding 1,20(1 gallons capacity, such loading and unloading connections shall be securely fastened to the skid or to the tank supports. NOTE: 2,000 pounds may not be adequate for all sizes of loading and unloading hoses and connections. (f) Where excess-flow valves (See Section 507 (e)] are used, liquid and vapor lines shall be at least full size from the excess-flow valve in the tank to the point of discharge or an additional excess-flow valve or eauivalent shall be located as close to thepoint of pipe size reduction or other restriction as is practical, unless the excess-flow valve in the tank is designed to operate at the reduced flow condition, in which case the excess-flow valve in the tank may suffice. Where excess-flow valves are used and 2 or more tanks are installed in battery, with common loading and/or unloading lines, the common ligw-d and vapor lines shall he fitted with excess-flow valves or equiva- lent (unless the common line has a cross-sectional area equal to or in excess of the combined areas of the individual tank lines; or unless the excess-flow valves are designed to operate at the reduced flow condi- tion, in which case the excess-flow valve in the tank may suffice). Where additional excess-flow valves are used in common loading and/ or unloading lines, the additional excess-flow valve or equivalent shall be located as close to the point of restriction as practical. NOTE: A quick-closing manually operated valve may be considered equivalent to an excess-flow valve at the point of pipe size reduction or other restriction providing: (1) It is equipped with a means of closing the valve manually from a point remote from the delivery connection. (2) The loading and/or unloading line in which it is located is secured to a bulkhead complying with Section 501 (e). (3) The quick-closing valve is in the pipeline on the tank side of the bulkhead. (g) Tanks installed in battery shall be so installed that the top sur- faces of the tanks are substantially in the same horizontal plane. (h) The following minimum equipment shall be installed, properly maintained, and readily available for use at all stationary storage tanks in readily accessible locations. (1) At least two full face respiratory devices in compliance with Section 5144; preferably one self contained breathing apparatus, and one ISH, gas mask with spare cannister. (2) One pair NH3 resistant gloves.
