An employee connected a hose from a chemical tank car containing about 34,000 pounds of aniline to a dripless connection, then actuated the pumping system to transfer the aniline (Aminobenzene) into an onsite holding vessel. The employee was splashed with aniline while disconnecting the transfer hose after the tank car was fully emptied. The employee's right thigh was contaminated with aniline; the employee was treated for aniline poisoning and hospitalized.
