Ethanolamines/Glycol Ethers Tier 3 Procedure Section Number: 1808 Issue Number: 1.1 Original Date: 07-08-94 Author: Revision Date: 12-29-95 Title: Line opening for lines containing flammables References: Glossary of equipment identification (txt #114) 1808 Line Opening For Lines Containing Flammables: 1.0 Objective: 1.1 To provide a procedure for the safe and effective opening of lines and equipment containing flammable products. 2.0 Scope: 2.1 The division has installed and energized several new deep well rectifiers in order to provide increased cathodic protection and reduced pipeline corrosion for both underground and aboveground piping in division pipeways. This additional voltage will result in an increased need for precautions against arcing due to additional stray currents during any process in which mating surfaces are being separated, such as line openings and valve or spool removal both in division pipeways as well as inside the plant. Increased protection is provided using a jumper across the opening whenever performing any of the above type activities on lines containing flammables. This procedure is not necessary if no flammables are present and this can be ascertained prior to flange or mating surface separation by checking a bleed, etc. This proc dure does not supercede other line opening procedures/requirements, but should be used in addition to those for flammable containing line openings. 3.0 Responsibility: 3.1 It is the responsibility of the operations supervisor and the lead senior operations specialist to ensure that this procedure is fully complied with. 3.2 It is the responsibility of the senior operations specialist and the operations specialist to ensure that this procedure is executed in a safe and efficient manner. 4.0 Procedure: 4.1 Determine if flammables are present in the system via a bleed. If present, the following procedure must be used. If not, line opening can be done without the use of jumpers. 4.2 Inspect the jumpers to insure that the cables, connections, and parts are in good shape.
