Section 912, Switch Unit Feed Pumps June 28, 2017 Pg. 1 VALERO MEMPHIS REFINERY TANK FARM OPERATING MANUAL PROCEDURE INFORMATION Purpose: This procedure describes the steps necessary to switch from one unit feed pump to another. This would be necessary if the pump were being taken offline for maintenance. Switching pumps on a regular basis also reduces wear on both pumps. Prerequisites: N / A Responsibility: The pumpers have the responsibility for switching unit charge pumps. Materials and Equipment: No special equipment is required Safety Requirements: No special safety precautions are required Personal Protective Equipment (PPE): Normal Tank Farm personal protective equipment must be worn at all times. This includes Hard Hats, Fire Retardant Clothing, Safety Glasses and Safety Shoes. Additional Protective Equipment may be required per the Permit Requirements. Quality Requirements: No special quality requirements Section 912, Switch Unit Feed Pumps June 28, 2017 Pg. 2 VALERO MEMPHIS REFINERY TANK FARM OPERATING MANUAL Operating Limits: Description Limits Consequences of Deviation Corrective and Avoidance Steps N/A Section 912, Switch Unit Feed Pumps June 28, 2017 Pg. 3 VALERO MEMPHIS REFINERY TANK FARM OPERATING MANUAL Chemical Safety: General information is provided here.
