LEDFORD SUMMARY/RECOMMENDATIONS V"X/. / / THE EMPLOYEES WITH A POTENTIAL EXPOSURE TO ASBESTOS WERE MONITORED USING AN APPROVED SAMPLING AND ANALYTICAL METHOD. FOUR (4) PERSONNEL SAMPLES WERE COLLECTED REPRESENTING JOBS OF HIGHEST ASBESTOS EXPOSURE POTENTIAL. NONE OF THE SAMPLES WERE FOUND TO BE ABOVE THE CURRENT EXPOSURE LIMITS. TEN (10) AREA SAMPLES WERE TAKEN IN AREAS OF HIGHTEST POTENTIAL EXPOSURE. THREE (3) OF THESE SAMPLES, ALL TAKEN ON THE SAME DAY IN THE ASBESTOS STORAGE ROOM DURING PULP MIXING, WERE ABOVE THE PERMISSIBLE EXPOSURE LIMIT. SCANNING ELECTRON MICROSCOPE ANALYSIS OF THESE THREE SAMPLES DETERMINED THAT ACTUAL ASBESTOS FIBER CONCENTRATION WAS BELOW THE PEL. A PERSONNEL SAMPLE TAKEN ON THE SAME DATE IN THE ASBESTOS STORAGE ROOM ON A CONTRACTOR MIXING PULP DID NOT INDICATE AN OVEREXPOSURE. IN ADDITION, THE EMPLOYEE WAS WEARING FULL PROTECTIVE EQUIPMENT AT THE TIME. PROCESS MODIFICATIONS WERE COMPLETED LATE IN THE YEAR WHICH INCLUDED INSTALLATION OF A NEW ASBESTOS DEBAGGER AND FILTER SYSTEM. THIS HAS ELIMINATED ALL MANUAL PULP MIXING WHICH WAS THE HIGHEST POTENTIAL EXPOSURE JOB IN THE PLANT. THE AUTOMATIC CATHODE WASHER WAS MODIFIED TO WASH ASBESTOS FROM ANODES WHICH HAD PREVIOUSLY BEEN DONE MANUALLY. ALL PERSONNEL WERE FIT TESTED USING IRRITANT SMOKE ON A SIX (6) MONTH FREQUENCY. RESPIRATOR TRAINING & MAINTENANCE ARE PERFORMED AT THE TIME OF FIT TESTING. THESE ACTIVITIES ARE DOCUMENTED. AN ANNUAL NOISE SURVEY SHOWED NOISE LEVELS HAD NOT INCREASED SINCE THE PREVIOUS YEARS SURVEY. ALL HIGH NOISE AREAS HAVE PROPER NOISE SIGNS. DISTRIBUTION LOUISIANA DIVISION MIDLAND QTHSi R.

ALL PERSONNEL SAMPLES WERE FOUND TO BE BELOW CURRENT EXPOSURE LIMITS FOR ASBESTOS. THREE AREA SAMPLES TAKEN NEAR THE PULP MIXING OPERATION IN THE ASBESTOS STORAGE ROOM ON THE SAME DAY WERE FOUND TO EXCEED THE PEL, ALTHOUGH THE PERSONNEL SAMPLE TAKEN AT THE SAME TIME WAS BELOW THE PEL AND ACTION LIMIT. ALL OTHER AREA SAMPLES WERE BELOW THE CURRENT EXPOSURE LIMITS. THE RESULTS OF THE MONITORING DATA IS SHOWN IN "ASBESTOS MONITORING RESULTS" ATTACHMENT #1 AT THE END OF THIS REPORT. \2. PROCESS MODIFICATIONS WERE COMPLETED THAT ELIMINATED THE MANUAL PULP MIXING JOB WHICH WAS THE HIGHEST POTENTIAL EXPOSURE IN THE PLANT. THE MODIFICATIONS INCLUDED A NEW ASBESTOS DEBAGGER, AND FILTER SYSTEM. 3. MANUAL WASHING OF ANODES WAS ELIMINATED. MODIFICATIONS MADE TO THE AUTOMATIC CATHODE WASHER HAVE ENABLED IT TO ALSO WASH THE ANODES. THIS ELIMINATED ASBESTOS FROM BEING WASHED ONTO THE CONCRETE SLAB WHERE IT WOULD HAVE TO BE CLEANED UP. ASBESTOS FROM THE ANODES IS NOW WASHED DIRECTLY INTO THE SUMP WHICH GOES TO THE CLARIFIER AND FILTER. 4. THE ANNUAL NOISE SURVEY CONFIRMED THAT NOISE LEVELS WERE ESSENTIALLY UNCHANGED FROM PREVIOUS SURVEYS. ALL HIGH NOISE AREAS HAD PROPER WARNING SIGNS POSTED. 5. ASBESTOS MONITORING DURING 1990 SHOULD BE CONCENTRATED AROUND THE NEW DEBAGGER SYSTEM TO DOCUMENT THAT FIBER LEVELS ARE WELL BELOW THE EXPOSURE LIMITS. 6. CONTINUE TO EVALUATE FURTHER USE OF ENGINEERING CONTROLS AND WORK PRACTICES TO REDUCE POTENTIAL ASBESTOS EXPOSURES EVEN MORE. 03/29/90 :0W MOtSE EXPOSURE EVALUATION 1989 AH AREA NOISE SURVEY HAS CONDUCTED USING A B&K MODEL 2205 HAND HELD SOUND LEVEL METER. IT HAS CALIBRATED USING A B&K TYPE 4230 AUDIO CALIBRATOR HHICH EMITS A 94 DB SOUND AT 1000 HZ. ALL MEASUREMENTS HERE TAKEN USING THE A-WEIGHTED SCALE IN THE SLOW RESPONSE MODE. THE RESULTS OF THE SURVEY ARE SHOWN ON THE BLOCK DIAGRAM IN ATTACHMENT 2 AT THE END OF THIS REPORT. AREA NOISE LEVELS HERE FOUND TO BE BASICALLY UNCHANGED FROM THE - PREVIOUS YEARS SURVEY. ALL HIGH NOISE AREAS (90 DECIBELS AND ABOVE) ARE POSTED HITH SIGNS REQUIRING THE USE OF HEARING PROTECTION. 03/2/90:DW ST0075 133 ACCOMPLISHMENTS FOR 1989 1. COMPLETED INSTALLATION OF AUTO DEBAGGER. DEMONSTRATED OPERATION USING BOTH REGULAR & COMPACTED ASBESTOS. 2. ELIMINATED THE MANUAL MIXING OF PULP. BY USING THE NEW DEBAGGER THE TIME REQUIREMENT TO MIX A TRAILER OF PULP WAS REDUCED FROM 6 HOURS TO APPROXIMATELY 30 MINUTES. IT ALSO CUT DOWN ON THE POTENTIAL FOR EXPOSURE TO ASBESTOS. 3. INSTALLED NEW FABRIC FILTER THAT MEETS "LESHAP" REQUIREMENTS. THE NEW SYSTEM HAS RESULTED IN INCREASED AIR FLOW THROUGH THE VENTING SYSTEM WHICH WILL REDUCE THE POSSIBILITY OF ASBESTOS FIBERS BEING RELEASED INTO THE AIR. M. CONVERTED TO THE CRADLE TYPE HEAD STRAP FOR THE MSA COMFOII RESPIRATOR. 5. INSTALLED TRAILER ACCESS PULP LOADING STATIONS. 6. MODIFIED AUTOMATIC CATHODE WASHER TO ALSO WASH ANODES WHICH HAD PREVIOUSLY BEEN MANUALLY WASHED. THE ASBESTOS GOES DIRECTLY TO THE CATHODE WASHER SUMP AND THEN TO THE CLARIFIER RATHER THAN ACCUMULATING IN THE DRAINS AND S-519 SUMP WHICH WOULD HAVE TO PERIODICALLY BE CLEANED OUT. 7. INSTALLED PNEUMATIC BAG MANIPULATOR TO PICK UP BAGS OF ASBESTOS FROM THE PALLETS AND PLACE THEM ON CONVEYOR TO THE DEBAGGER. THIS EQUIPMENT GREATLY REDUCES THE PHYSICAL EFFORT REQUIRED TO LIFT AND MOVE THE BAGS REDUCING THE POTENTIAL FOR BACK INJURIES. 03/12/90: DW ST0075134 ST0075 135 GOALS AMD BLAHS TQR 199Q 1. A PARTICLE DETECTOR HAS BEEN ORDERED TO BE INSTALLED ON F-509, WHICH WILL DETECT FILTER BREAKS. THE DETECTOR WILL GIVE AN ALARM & SHUT DOWN BLOWER. AN INTERLOCK HAS BEEN ORDERED THAT WILL SHUT DOWN F-509, BL-509, & L-501 (BAGUFTER). - 2. A LIGHTING SURVEY OF THE BUILDING IS UNDERWAY TO IMPROVE THE LIGHTING. 3. RAISING OF P-501 A/B (SUMP PUMPS) TO GROUND LEVEL IS BEING STUDIED. OPERATORS MUST ENTER THE SUMP DAILY TO CHECK EQUIPMENT. N THIS IS CONSIDERED A VESSEL ENTRY. 4. CONCENTRATE ASBESTOS ACTIVITIES AROUND THEE NEW DEBAGGER OPERATIONS. 03/30/90:DW MaSCELLANEOUS ACTIVITIES SOME OTHER INDUSTRIAL HYGIENE RELATED ACTIVITIES THAT OCCURRED DURING THE YEAR ARE LISTED BELOW: 1. HAZARD COMMUNICATION-ALL EMPLOYEES WERE PRESENTED INFORMATION ON THE HAZARDS OF THE CHEMICALS IN THE BLOCK INCLUDING WHERE THEY ARE USED AND PROPER PROTECTIVE MEASURES. EXPOSURE MONITORING DATA WAS ALSO PRESENTED. ALL OF THE ABOVE WAS DOCUMENTED. 2. RESPIRATOR PROGRAM- ALL PERSONNEL WERE FIT TESTED USING IRRITANT SMOKE ON A SIX MONTH FREQUENCY. RESPIRATOR USE TRAINING AND MAINTENANCE ARE PERFORMED AT THE SAME TIME. TWO POWERED AIR PURIFYING RESPIRATORS ARE AVAILABLE FOR USE BY EMPLOYEES WHO V PREFER THEM TO THE DUAL CARTRIDGE HALF FACE RESPIRATORS. 3. VENTILATION - THE LABORATORY FUME HOOD AND LOCAL VENTILATION SYSTEMS AROUND THE ASBESTOS HANDLING OPERATIONS WERE EVALUATED FOR PROPER AIR FLOW BY INDUSTRIAL HYGIENE. ALL WERE FOUND TO BE WORKING PROPERLY. 4. HEALTH TEAM REVIEW-THE ANNUAL HEALTH REVIEW WAS HELD TO REVIEW THE INDUSTRIAL HYGIENE PROGRAM IN CELL SERVICE. THE HAZARDOUS CHEMICALS IN THE PUNT WERE REVIEWED INCLUDING HOW THEY ARE HANDLED AND PROTECTIVE EQUIPMENT REQUIREMENTS. THE EXPOSURE MONITORING DATA WAS DISCUSSED IN DETAIL 5. ASBESTOS TRAINING-A SPECIAL MEETING WAS HELD TO CONDUCT THE TRAINING SPECIFIED IN THE OSHA ASBESTOS STANDARD 29 CFR 1926.58. ALL PERSONNEL IN THE PUNT ATTENDED THE MEETING. (THIS WAS DOCUMENTED). 03/27/90: DW ST0075I 36 ST0 0 7 5 137 ATTACHMENT #1 PAGE 1 ASBS8T0S MOSXTOBXVG RI8ULT8 CELL SERVICE, BLOCK 56, LA.
