NOTE 1: When two or more classes of
								materials are stored in a single pile, the maximum gallonage in that pile shall
								be the smallest of the two or more separate gallonages.
NOTE 2: Within 200 feet of each
								container, there shall be a 12-foot wide access way to permit approach of fire
								control apparatus.
NOTE 3: The distances listed apply to
								properties that have protection for exposures as defined. If there are
								exposures, and such protection for exposures does not exist, the distances in
								column four shall be doubled.
NOTE 4: When total quantity stored
								does not exceed 50% of maximum per pile, the distances in columns four and five
								may be reduced 50%, but not less than three feet.
(b) The storage area shall be graded in a
					 manner to divert possible spills away from buildings or other exposures or
					 shall be surrounded by a curb at least 12 inches high. When curbs are used,
					 provisions shall be made for draining of accumulations of ground or rain water
					 or spills of flammable or combustible liquids. Drains shall terminate at a safe
					 location and shall be accessible to operation under fire conditions.
(c) All available precautions shall be taken
					 to protect the storage area against tampering or trespassers where necessary.
					 The area shall be kept free of vegetation and combustible material.
(d) Each portable tank shall be provided with
					 one or more devices installed in the top with sufficient emergency venting
					 capacity to limit internal pressure under fire exposure conditions to 10 psig,
					 or 30 percent of the bursting pressure of the tank, whichever is greater. The
					 total venting capacity shall be not less than that specified in Section
					 1932(e) below. At
					 least one pressure-actuated vent having a minimum capacity of 6,000 cubic feet
					 of free air per hour (14.7 psig and 60°F.) shall be used. It shall be set
					 to open at not less than 5 psig. If fusible vents are used, they shall be
					 actuated by elements that operate at a temperature not exceeding 300°
					 F.
