Typical accident case:

 On January 7, 2010, the CNPC Lanzhou Petrochemical C4 spherical tank exploded and caught fire, resulting in 6 deaths and 6 injuries. The main cause of the accident was the failure and rupture of the pyrolysis C4 spherical tank outlet pipeline and material leakage. The leaked pyrolysis C4 reached the explosion limit, and space explosion occurred when it encountered the ignition source, which in turn caused leakage, fire and explosion of surrounding storage tanks.

        Notice: The "Static Grounding Monitoring System" functions as a part of an Overfill Protection & Earthing System. These provide a visual green light indicating a confirmed grounding condition of road tanker vehicles during the transfer of flammable and combustible materials. A red light indicates the absence of dependable grounding. An interlock circuit inside the control panel will prevent pumps and equipment from starting until a satisfactory ground is established. The interlock circuit will also shut off pumps and equipment if the ground is lost during the pumping operation.
