Objective Procedures: a L.H C. #3 will be shutdown when hurricane winds exceeding gust of 98 mph or sustained winds of 75 mph are predicted to strike within 6'to 8 hrs. Note *** Production planning should be informed that L.H.C. #3 will need at least 6 hrs to secure the plant. This means that user plants will be affected by jack of feed supply h Plant personnel will be kept informed of all per tinen t hurricane activity, c , Adequate preparations shall be made to minimize win: arid water damage should hurricane winds strike. Orders will be issued to prepare/ when the storm has a predicted path within 75 miles of plant or when winet exceeds 65 mph gust. This will be done in =ufficent time to allow a full eight-hour day for c>r eparat i ons : it w:3J be tr.e i.

Oncoming shift will not be expected to report to work when the weather conditions do not permit safe travel. *** Otherwise be here to give us s me V relief!!!! *** f. Operating and all other personnel will remain until there relief can report safely to work. g. Hurricane Stages (Once Hurricane Watch is issued) 1. Family plans and preparation should be reviewed. 2 *** Stand-by *** begins at approx imately 24 hrs before the expected arrival of 65 mph gust. a. Hurricane personnel will be advised the plant is on stand-by and that they may be called for duty. b. All personnel continue to report for work on their normal schedule. c. Preparations will be begin for securing loose items in the plant. d A number of maintenance personnel will be ne ded for each technical er>gineers area for securing that section of the plant. General List of Secured Items ] Trash cans and Barrels 2 All fire extinguisher's in place 3 All utility hoses at stations 4 Ladders 5 All waste d rums Tool boxes 7. Empty all trash dumpsters 3 Pick up or tie down all loose items A Tie down or relocate vessel entry trailers to warehouse 10. Secure Beniene/Ethy1ene furnace penthouse doors 11 Secure all scaffold boards and plywood 11'. Secure all compressed gas cylinders 13 Secure all overhead cranes 14. Tie off chains for all overhead hoists and valve operators 15. Check analyzer gas supply and secure cylinders 16. Install life line between warehouse and control room buildings also between control room and M. C. C. DO A 034448 CONFTDFNTIAL 3. Preliminary Alert: This begins approximate1y 16 hrs. before the expected arrival of the 65 mph gusts. a. Additional personnel may be called out as needed. b. Assigned hurricane personnel should finalize their family plans and preparations. c. A final check of the plant for loose items. 4. Final Alert: This begins approximate1y 10 hrs. before the arrival of the 65 mph. gusts. a. All hurricane personnel not already on the plantsite will be called out at this time. b. All personnel not required at the plantsite will be release to go home. c. Kay need to initiate a partial shutdown at this time. ( E T. X. section if possible. ) 5 Flant Shutdown: T ft i s begins if it is judged that the plant will be exposed to wind gust exceeding 98 mph. or 75 mph sustained a, Contact production planning so they can contact all LHC. #3 user plants and feed suppliers to determine their hurricane plans, r. This is general list of what should be done during and after the shutdown: 3. Proceed with a normal furnace, ethylene, and benzene shutdown per/guidelines. Remember all furnaces should be swapped to firebox without decoking before final shutd own C Cocl CMC at 50 deg. /hr. using py-gas to prevent quench oil from solidifying. 3 Close all furnace and vessel outlet valves. ^ Close all block limit valves on import and export ------> Ethylene. Ethane. Propylene. Propane Hydrogen, Fuel gas Note *** Make a list of all the valves on these headers that are closed. 5. Leave all towers pressured up and maintain a liguid level. 6. Put all pump switches in the off position. 7 Drain all cold liguid piping that is block in on both ends. Remember this prevents thermal expansion and line ruptures. (example: Ethylene lines) B. Secure C-10 and C-20 from a vacuum, use nitrogen to prevent from flaring if possible. 9 Secure cooling tower fans. 10. Leave the benzene plant under nitrogn pressure. DO A 034449 CONFIDENTIAL 11. Leave 70'/. level in (2) of the ethylene and propylene bullet tanks for start-up inventory. Line up equalizing line on ethylene drums to the flare for pressure control. Also maintain drum pressures higher than tower to prevent possible contamination. 12. Utility area: All chemical pot areas secure with pumps off after boilers come down. Be sure all pots are fastened down good and they should be filled about half way or full. 13. Secure V-1300 area and turn off pumps. Also secure CT-1000 pumps and chemical addition. ; Final Note f-'t this tire the plant should be secure enough so that personnel should not ha\e to leave the control room except for emergency reasons Michael Jenkins 00 A 0344 SO conf r dfimt t ai
