ACCOMPLISHMENTS LHC III 1981
1. Every three months CBC and urinary phenols were run on all the OT's and S.O.T.'s. O.S.'s were included at six months intervals.
2. Every personnel were monitored for potential exposure to benzene while working in clean up of pyrolysis gasoline spills. Urinary samples were collected at the beginning of the day and at the end of the day to check for any increase in phenol levels. Everyone did wear a half face respirator while working at the spill.
3. A noise survey was run in November. Signs were posted indicating the highest noise area. (Above 90 decibels)
4. Sixty nine boxes to hold six half face respirators were mounted in various sections of the plant. This eliminated the need to carry around a respirator. Once a month the boxes are checked to see that they contain the required number of respirators.
5. We had a 99% participation in the respirator fit test program for the operators, and 84% participation in the program from the technical personnel.

GOALS AND PLANS FOR 1982
1. CONTINUE TO IlfURM ALL PLANT PERSONNEL ON BENZENE TOXICITY DATA.
2. TAKE EXCURSION DATA IN AREA WHERE PERSONNEL MAY BE EXPOSED TO BENZENE WHILE CHANGING FILTERS, OR PUT SEALS AND ETC.
3,. DEVELOP METHOD FOR RUNNING AIR SAMPLES FOR DICYCLOPENTADIENE, METHYL CYCUOPENTADIENES AND BIPHENYL.
A. TAKE EXCURSION DATA IN VARIOUS AREAS OF THE PLANT TO DETERMINE EXPOSURE TO DICYCUDPENTADIENE, BIPHENYL AND PETHYL CYCLOPENTADIENE.
5. START A PROGRAM TO DETERMINE HOW MUCH EXPOSURE HERE IS TO WELDING FUFES IN THE WAREHOUSE.
6. COLLECT AIR SAMPLES TO CHECK FOR PETALS WHEN CATALYST IS BEING DIM).
7. CONTINUE TO MONITOR PERSONNEL FOR EXPOSURE TO BENZENE WHEN CLEANING UP SPILLS. INIS INCLUDES TAKING URINE SAMPLES BEFORE AND AFTER THE WORK PERIOD.
8. RUN YEARLY NOISE SURVEY.

1981 ACCOMPLISHMENTS
LHC I
1. Completed annual 8 hour exposure monitoring for benzene and toluene. All job classifications were monitored in the survey.
2. -Completed annual area noise survey. Caution signs are located in areas where noise levels exceed 85 dB.
3. All employees were informed of the benzene, toluene, and noise exposure results. Consequences of overexposure were .also covered for benzene, 1-3 butadiene, TBC, caustic, MMC, slop oil, styrene, toluene, xylene, and noise.
4. Twenty-seven boxes containing six half-face (Comfo-II) respirators were mounted throughout Blocks 38 and 39. This eliminated the need to carry a respirator in these areas. The boxes are checked monthly to make sure each box contains six unused respirators.
5. We had 100% participation in the respirator fit test program, i including operators, technical personnel, and permanent block
contract maintenance.

( 1981 ACCOMPLISHMENTS
LHC II
1. Fit-tested 100% of permanent block personnel for the "Comfo II" respirators.
2. Established 18 respirator "station" throughout the block. Each "station" consists of a bright yellow box, containing 6, "Comfo II" respirators, mounted in a highly visual location. These boxes are maintained by the block Safety Chairman.
3. Continued our program of checking C3 pumps, when being disassembled for maintenance, for radiation. So far, we have not found any significant radiation.
4. Checked all pumps in the block that pump propane or propylene material, for gamma radiation and discovered only insignificant amounts.

GOALS AND PLANS FOR 1982: LHC I AND LHC II
1. Increase short term excursion sampling for .exposure to hazardous chemicals. Concentrate on specific areas of the plant and specific duties which may expose plant personnel to high levels of benzene. Monitor each vessel entry, on an individual basis, for toxic agents.
2. Clean waste oil area to reduce contact with waste oil.
_ 3. Improve documentation of Industrial Hygiene information. Include consequences of overexposure of hazardous chemicals, handling procedures for hazardous materials, and results of exposure surveys in a single volume made accessible to all block personnel. Use this volume to increase employee awareness of Industrial Hygiene procedures and precautions.
4. Collect noise and benzene exposure data during plant shutdowns, startups, and upsets.
5. Repair mufflers on furnace burners and put lead shields on lines and valves which are excessively noisy.
6. Continue annual 8 hour TWA benzene/toluene exposure surveys.
7. Continue area noise exposure surveys and collect personnel noise exposure data.
8. Continue to inform employees of survey results and ronsequences of overexposure of hazardous chemicals in the block.
9. Test for B radiation from scale on C3 pumps before beginning maintenance work.
10. Investigate possible overexposure to Kaswool in furnaces.

In January 1981, LHC III had two different pyrolysis gasoline spills. The first spill was contained in the rain water pit, and the second in the ditch beside LHC II. The pyrolysis gasoline was pumped off the top of the water, transferred to a small bullet tank and then transferred back into the process. All personnel (47) working on the clean up wore protective clothing and respirator protection. The respirators used were Comfo II manufactured by Mine Safety Appliances Co. with the MSA GMC type chemical cartridge for acid gases and/or organic vapors.
Potential exposure to the benzene and toluene vapors was mon itored by collecting urine samples for phenol analysis from each person before and after the exposure. The urine samples were sent to an independent laboratory for analysis. In add ition to the urinary phenol analysis, the employees were sent to Medical for a red and white blood cell count.
The level of potential exposure was measured by having each person wear a 3M 3500 organic vapor monitor. The monitors contained activated carbon which absorbed the contaminate in the atmosphere at a known sampling rate. The volune of the sampling is a product of the sampling rate and the length of the sampling period. The weight of the contaminant (benzenetoluene) collected by the monitor was determined by desorbing the contaminant in carbon bisulfide, then with gas chromato graphic techniques, the weight of contaminant In the solvent (CS2) was determined. The time weighted average (TWA) concen tration of the contaminant (benzene-toluene) was determined by measuring the weight of contaminant in a known volune.

Conclusion: Report from Medical on the blood counts and the urinary phenols clearly indicates that no one was exposed to the high level of benzene found by the 3M monitors, which leads one to believe the double cartridge respirators are the right ones to use for the clean up of pyrolysis gasoline spills. The 3M monitors are simple to use and they have proven to be reliable indicators of benzene exposure at low levels, however, from samples 2, 6, 8, 2-2, and 2-6 one might conclude that the adsorption takes place in the first couple of hours at a faster rate than when the monitors are worn all day. The 3M literature recommends exposure limits of 3000 ppm, or less. This indicates that, at the level of benzene and toluene we found, the monitors should have been effective for the full 12 hours. Next time I will run the same controls and change the monitors more frequently. It is suspected that samples 20 and 21 on Jan. 21, 1981 were contaminated by the liquid pyrolysis gasoline.
