Bordelon D0 093778 confidential CHLORINATED METHANES PLANT INDUSTRIAL HYGIENE JOB ANALYSIS A. Introduction The Plaquemine, Louisiana Chlorinated Methanes Plant WAS MONITORED DURING 1979 IN A ROUTINE AND CONTINUAL SURVEY OF THE CHEMICALS AND NOISE PRESENT IN THIS block. Listed below are the chemicals plus noise., WITH THEIR RESPECTIVE STANDARDS: Chemical Standard (TLV) Methyl Chloride Vinyl Chloride Methylene Chloride Chloroform Carbon Tetrachloride Methanol Ethylene Dichloride B-trichloroethane Dimethyl Ether 1,1,1 Trichloroethane (degreaser) Chlorine Hydrochloric Acid Sulfuric Acid Noise 50 ppm 1 PPM 200 ppm 10 PPM 10 PPM 200 ppm 50 ppm 10 ppm A00 ppm 350 ppm 3 mg/m3 7 mg/m3 1 mg/m3 85 DBA -1- DO 093729 COMFTDF.NTTAV. B. Conclusions from 1979 Survey A CMPll employees in the block were monitored using PERSONAL MONITORING. MOST WERE MONITORED A MINIMUM . OF THREE OR FOUR TIMES DURING THE YEAR AND ALL THE JOBS WERE COVERED. ENOUGH DATA WAS COLLECTED TO SHOW THAT EMPLOYEES ARE WITHIN THE THRESHHOLD LIMITS WHEN PERFORMING ROUTINE JOBS DAY IN AND DAY OUT. OCCASION ALLY, A HIGH READING SHOWS UP WHERE THERE ARE NO REASONABLE EXPLANATIONS. ONE SUCH HIGH WAS A 9.1 PPM B-TRICHLOROETHANE READING FOR THE SECRETARY. ANOTHER EXAMPLE IS WHERE THE SECRETARY HAD A 33,2 PPM METHYL CHLORIDE LEVEL WITH A 16.7 PPM ETHYLENE DICHLORIDE LEVEL ONE DAY, WITH LEVELS OF 38.1 PPM METHYL CHLORIDE AND 14.1 PPM ETHYLENE DICHLORIDE RECORDED BY THE ASSISTANT CHEMIST. On THESE MENTIONED OCCASIONS, BOTH OF THESE PEOPLE'S ACTIVITIES HAD BEEN PRIMARILY CONFINED TO THE OFFICE BUILDING; THE SECRETARY SPENDING HER DAY IN HER OFFICE. ANALYTICAL PROBLEMS HAVE CREATED SITUA TIONS WHERE THE TIME SPAN BETWEEN THE MONITORING AND THE ANALYSIS WAS SUCH THAT IT WAS DIFFICULT FOR THE PERSON BEING MONITORED TO RECALL PERTINENT DETAILS WHICH MAY HAVE CONTRIBUTED TO ELEVATED EXPOSURE LEVELS (AS WAS HERE). At THIS POINT THE ANALYTICAL PROBLEM SEEMS TO BE CORRECTED AND FUTURE SAMPLES SHOULD BE ANALYZED SOON AFTER THE MONITORING. Excursion monitoring for millwright work and for fitters OPENING REBOILERS AND LINES IS STILL BEING DONE AND CONTINUES TO POINT TO ELEVATED EXPOSURE LEVELS. THESE JOBS REQUIRE BREATHING AIR WHILE PEOPLE ARE WORKING IN THESE AREAS. -2- DO 093730 CONFTDFNTTAI. B. Conclusions from 1979 survey (cont'd) Some of the use of 1,1,1 trichloroethane (especially indoor) has been reduced in this block when the INSTRUMENT PEOPLE CEASED CLEANING AND REBUILDING CONTROL VALVES HERE. THE CURRENT PRACTICE IS TO DECONTAMINATE THE VALVES WITH STEAM AND TO TAKE THEM TO THE MAIN INSTRUMENT SHOP FOR REBUILDING. NIOSHThe 1979 monitoring timetable was upset by a REQUEST TO MONITOR OUR PLANT IN MID-SUMMER, THIS SCHEDULED VISIT WAS ABORTED BY A HURRICANE WATCH AND RESCHEDULED FOR EARLY FALL. THIS VISIT DID NOT MATERIALIZE EITHER BECAUSE OF A PLANT SHUTDOWN WHICH OCCURRED THAT WEEK. OUR INDUSTRIAL HYGIENE PEOPLE HAD WANTED TO DUPLICATE THE NIOSH MONITORING BY EMPLOYING IDENTICAL EQUIPMENT AND TECHNIQUES AS NIOSH FOR COMPARISON PURPOSES. Some goals for 1980 are: 1. Use of plant air for breathing air on jobs where BREATHING AIR IS REQUIRED. PLANS ARE FOR INSTALLING STATIONS IN THE AREAS WHERE JOBS REQUIRING BREATHING AIR ARE APT TO BE NEEDED. THESE STATIONS WILL UTILIZE INDICATING FILTERS AND PRESSURE REGULATORS. Meanwhile, plant air is being monitored for CO LEVELS,.WITH .RESULTS INDICATING LEVELS OF LESS THAN 4 PPM, If PLANT AIR CAN BE UTILIZED IN PLACE OF CYLINDERS, IT WILL FREE PEOPLE FROM THE TASK OF HAVING TO HAUL CYLINDERS (BREATHING AIR) ALL OVER THE PLANT. UNDER THE PRESENT PRACTICE OF USING BREATHING AIR CYLINDERS, IT IS POSSIBLE FOR MORE TIME TO BE CONSUMED IN THE LOCATING OF A CART, GETTING A CYLINDER OUT TO THE JOB, AND RETURNING IT AFTER THE JOB IS FINISHED, THAN THE TIME ACTUALLY SPENT ON THE JOB ITSELF. 00 093731 C0^IDENTTAl B. Conclusions from 1979 survey (cont'd) 2. Construction and use of a work bench with exhaust HOOD IN THE WAREHOUSE FOR USE PRIMARILY WHEN CLEANING PUMP PARTS WITH CHLOROTHENE. 3, Use of noise dampening material in the warehouse to absorb noise from grinding and other noise generating activity, DO 093732 CONFIDENT TA1. C, Monitoring results Personnel monitoring using charcoal adsorption tubes was employed to cover all the jobs for the following chemicals: vinyl chloride, methyl chloride, dimethyl ETHER, METHYLENE CHLORIDE, CHLOROFORM, CARBON TETRA CHLORIDE, ETHYLENE DICHLORIDE, AND B-TRICHLOROETHANE.

Monitoring results (cont'd) Area monitoring was employed to check for methanol and 1,1,1 trichloroethane (a degreaser used in the cleaning of pump parts). For methanol, samples were collected in saran bags at various points through out THE PLANT, SAMPLE RESULTS AVERAGED, AND TWA FIGURES WERE OBTAINED BY USING THE AVERAGE TIME SPENT IN THESE AREAS FOR EACH JOB. ALL OF THE . MONITORING FOR CHLOROTHENE WAS DONE IN THE WAREHOUSE WHERE IT IS USED TO CLEAN PUMP PARTS. THE HIGHEST READING WAS A.3 PPM, WHICH WAS TAKEN CLOSE TO AN OPEN CONTAINER IN A MILLWRIGHT'S WORK AREA. Monitoring for chlorine, hydrochloric acid, and SULFURIC ACID WAS CONDUCTED BY SCRUBBING AIR WITH DISTILLED water for HCl and sulfuric acid, and WITH 1.0 N. NaOH FOR CHLORINE FOR 7-8 HOURS PER SAMPLE. A TOTAL OF 20 SAMPLES WERE TAKEN, Chemical Standard Highs in ppm High/Job Average High/Area Reading Methanol 200 1,1,1 tri chloroethane Chlorine Hydrochloric Acid Sulfuric Acid 350 i 5 .25 SOT 4.7 EDO 4.7 Cont .

Monitoring results (cont'd) / Excursion monitoring for hexes was conducted on main tenance jobs on RE-1 (the tar pot exchanger), C-806 REBOILER AND ALSO MILLWRIGHT WORK ON.A 1XR POT PUMP, AND SAMPLES WERE SUBMITTED TO THE INDUSTRIAL HYGIENE GROUP FOR ANALYSIS. IH WAS HAVING ANALYTICAL PROBLEMS ABOUT THAT TIME, AND WHEN THEY FINALLY TRIED TO RUN THE SAMPLES THEY COULD NOT PRODUCE ANY VALID RESULTS. A Sampling for dust was conducted during the dumping of OLD CATALYST AND RECHARGING OF THE R-250'S. IN MAY, R-250 A WAS RECHARGED WITH NEW CATALYST.AND R-250B WAS RECHARGED IN NOVEMBER. RESULTS OF THE MONITORING SHOWED: Job MONITORING operator location irI ME HRS DUMPING OLD CATALYST REACTOR MANWAY 1 DUMPING OLD CATALYST BY DUMPSTER 1 BLOWING NEW CATALYST (OUT OF TUBES) (2 OPERATORS) TOP OF REACTOR 5 BLOWING NEW CATALYST (OUT OF TUBES) (2 OPERATORS) TOP OF REACTOR 2 DUST3 (MG/M 1.85 1 . 19 3.15 3.81 <0.50 <0.50 Area noise surveys - the basic difference in readings WITHIN SPECIFIC AREAS IS THAT OF ELEVATED READINGS CAUSED BY STEAM TRACING IN WINTER MONTHS. SOME OF THIS EXTRA NOISE COULD BE MINIMIZED. STEAM LEAKS ARE ALSO MAJOR NOISE SOURCES. SINCE STEAM DOES NOT POLLUTE THE ATMOSPHERE SUCH AS PRODUCT SPILLS DO, STEAM LEAKS TEND TO BE IGNORED UNTIL THEY DEVELOP INTO MAJOR LEAKS BEFORE REPAIRS ARE MADE. -7- DO 093735 CONFIDENTIAL t INDUSTRIAL HYGIENE JOB ANALYSIS VERSUS % OF HYGIENE STANDARD Standard Methyl Chloride Vinyl Chloride Methylene Chloride Chloroform Carbon Tetrachloride Methanol Ethylene Dichloride B-trichloroethane Dimethyl Ether 1,1,1 Trichloroethane Chlorine Hydrochloric Acid Sulfuric Acid Noise 50 ppm 1 PPM 200 ppm 10 PPM 10 PPM 200 ppm 50 ppm 10 ppm A00 ppm 350 ppm 3 mg/m3 7 mg/m3 1 mg/m3 85 DBA 100% 50-100% 25-50% 10-25% <10% - - 2 29 - - 1 A8 - - - - 13 - 1 1 7A - - - 3 10 13-- - - - - - 1 12 - - 1 2 10 - - - - 13 - - - - 13 - - - - 13 - - - - 13 - - - 3 10 1 57 TOTAL % of TOTAL JOBS Data based on TWA 0 o.oo 1 6 27 148 *55 3-30 1^.83 81.32 i DO 093736 CONFTDF'NTTAL -8- Mr" i INDUSTRIAL HYGIENE SAMPLE RECORD fll NUMBER PROCESS CHLS&jfJftreA AlerMAtjzS BLDG NO.
