i 1.0 INTRODUCTION Chemical Transfer Co. (Chem. Tr.) operates a facility at 1033 Stokes Avenue, Stockton, CA, at which bulk chemicals are transferred from rail cars to truck trailers for delivery to users in the Stockton area. On November 25, 2001, a quantity of 220 baume hydrochloride acid was accidentally released from a rail car. This Health and Safety Plan (H& S)has been prepared to outline the safety precautions to be taken, including use of personal protective equipment (PPE),to ensure the safety of all personnel involved in cleanup activities and persons at adjacent locations, and to mitigate potential effects to the environment. 2.0 DESCRIPTION OF ACTIVITES G. W. Roy, P.E., from Environeering, Inc. is in charge of the cleanup operation. He will review the Work Plan and the H& S Plan with all personnel involved in the cleanup and will require strict adherence to the procedures outlined herein, and use of the proper PPE. 10 Immediate actions taken upon discovery of the release included neutralizing the hydrochloric acid with lime rock. This stopped the evolution of hydrogen chloride vapor and generally stabilized the area. The work to be undertaken at this time, covered by this H& S Plan, involves spraying a dilute solution of caustic (sodium hydroxide) over the affected area, and sampling and testing pH using pH paper,to ensure that all acid has been neutralized. 3.0 POTENTIAL HAZARDS The principal hazard to personnel engaged in neutralizing the hydrochloric acid is from chemical burns from contact with either hydrochloric acid or sodium hydroxide. The eyes are most sensitive to these chemicals, followed by contact with the skin. Particular care must be exercised while spraying the caustic solution over the affected area, and while taking samples for pH testing. Personnel must wear appropriate PPE, listed below, during these operations.
