				arranged so liquid spillage will drain away from the truck and exposed
				structures. The pad will be of sufficient length to allow the truck and trailer
				a minimum of four-foot clearance at each end of two-foot clearance on each
				side. Because of the hazard of backing equipment into roadways and the possible
				need to move a truck quickly from the unloading place, it will be so arranged
				that the truck can be driven away in a forward direction.
D. Only qualified and properly instructed
				employees will operate the truck and make the hook-up of the hose from the tank
				truck to the receiving tank.
E.
				Before connecting for unloading, the truck engine will be stopped and not
				started again during the entire unloading operation until it is necessary to
				operate the pump by power take-off or to use the truck engine to operate
				compressors as a source of air for air pressure unloading.
F. Truck parking brakes will be set and,
				where necessary, the wheels blocked.
G. A sign will be placed at all areas where
				acid is loaded and unloaded, calling attention to the hazard.
H. Whether unloading by pump or air, the
				piping will, if possible, be arranged so the acid will drain toward the storage
				tank when the pump is shut down or when the discharge valve is
				closed.
I. When unloading line must
				be run across a walkway, suitable warning signs will be provided to denote the
				hazard.
J. Before starting to vent
				or connect, a water hose will be connected and ready for emergency use and the
				emergency shower and eye bath will be tested.
K. Wherever practicable, unloading will be
				accomplished by pumping. Whether pumping or unloading by air pressure, observe
				the following procedure:
1. Operate the relief
				valve to vent the tank.
2. Remove
				blind flange from air inlet line.
3. Leave this line open during
				pumping.
4. After making certain
				there is no air pressure, remove blind flange from standpipe and connect
				unloading line to standpipe.
