Has the Technology Center approved the process? Yes, see attached copy of support letter. Also includes is CATC DesignGuideline Module 14 "Chlorine Scrubber System". 2. Has any reactive chemical data been generated? Yes, see attached copy of Titanium/Dry Chlorine reaction conditons verses scrubber operating conditions graph. Also attached is Reactive Chemical Committee Support Letters. 3. Has a reactive chemical review been done since the design was finalized? __YES________ Attach the review letter along with a written answer to any questions that were raised during the review. Has reactive chemical checklist been completed? YES, ATTACHED 4. Has Environmental Control reviewed and approved the project? Support letter from Environmental Services is attached When the construction project is essentially complete, a job safety inspection should be made, This inspection should m- elude: Plant Supervisors Plant Operators Plant Engineer/Mfg. Rep. Safety Department Their inspection should emphasize: Pipe, valves, fittings, and associated supports Valve location and orientation Structures and ladders Electrical grounding Insulation for personnel protection Safety showers Fire extinguishers and deluge guns Intercom locations Lighting Line labeling DO A 023418 CONFIDENTIAL Freeze Protection PSV's Instrumentation Has such a review been made? No, will be scheduled Operator training classes should be held. These class s should highlight the following: PRE-START UP AUDIT - C-6 PAGE 2 A. Project benefits and expected results. B. Process description (include expected operating conditions) C. Process controls D. Operator responsibilities E. New procedures: 1. Start up 6. Normal Operating Procedures 2. Emergency 7. Red Tag 3. Shutdown 4. Sampling 8. Loading/Unloading 9. Freeze Precautions 5. Job Procedures (norma1/severe) Lab Procedures Has such training been done? YES, see attached training sch. 7. Procedures should be reviewed by as many plant people as possible and revised as necessary. A plant committee of operations and technical people should make a final safety audit of procedures. Has such a safety audit been done? Yes, IPT modules were generated by operations personnel. These IPT modules used the MOD V program documentation and Operating Discipline as resources. 8. Has the system been pressure tested? _____No, this will be completed prior to start-up. Washed or cleaned? No, this well be completed prior to start-up. How? ____The system will be "run" on water. 9. Is it possible to have a dry run operation such as operating the system on air, nitrogen, or water? yes If so, has this been done? _______Not yet________ Are other plants involved in the new process? no 10. Have all instrument loops been checked and documented? All instrumentation checkout will be completed prior to start-up. Full range valve stroke? __________Fail safe valve positions verified? ______ Have critical instruments been identified and registered? in process 11. Has the new electrical equipment been checked out? Are field switches, equipment and MCC starters labeled properly? Refer to S--316 for electrical safety standards. WILL BE COMPLETED PRIOR TO START-UP ____ _____ 12. Hav the block operating manual and emergency procedures been modified to include the new project? _____yes 13. Have pressure vessels and PSV's been added to the computer list? YES _________ Do PSV's set pressure match design pressures of vessels? N/A 14. Have plant and engineering files and drawings (P&ID's) been updated to include the new equipment? yes DO A 023419 CONFIDENTIAL PRE-START UP AUDIT - C-6 PAGE 3 15. Has a list of necessary spare parts been added to the existing , spare parts stocking list? 16. Have training classes been set up for maintenance of the new equipment: __ 17. Has all associated equipment been checked? YES 18. Has a review of the control system been completed? _yes If computer control, has a simulation been done? _yes This check sheet must be filled out and reviewed with the Plant Superintendent prior to the start up of a new project. 11/90 t, 023*20 DO PRE-START UP AUDIT - C-6 PAGE 4 PROJECT AND MODIFICATIONS SAFETY ASSESSMENT 'LANT __Chlorine I TITLE _Scrubber Project ** those factors which have been changed by the proposal.
