Dow's Industrial Hygiene Guide calls for a 10 (ten) ppm ceiling and does not allow short term excursions above this ceiling. In December 1987, the Osha Standard for Benzene went into effect. This . reduced the permissible exposure limit of benzene to 1 ppm (TLV-TWA) for 8 hours, and the short term exposure limit (stel) not to exceed 5 ppm average for 15 minutes. The 3M organic vapor monitor badge (#3500) was used to obtain breathing zone samples of operators working in areas most likely to contain benzene. The badges, which use an active charcoal wafer as a collection medium, were desorbed with carbon disulfide and analyzed by gas chromatography. 1. PERSONNEL MONITORING As shown on Table 1 (Attachment 1) the personnel samples were well below the 10 ppm TLV-TWA. This agrees with historical data. See also Attachment 2. TOLUENE EXPOSURE EVALUATION Explanation of Guidelines and Sampling Method The AGGIH Threshold Limit Value (TLV-TWA) for toluene is 100 ppm with a TLV-STEL of 150 ppm. The TLV-STEL is a 15 minute exposure guideline. The 3M organic vapor monitor badge (#3500) was used to obtain breathing zone samples of operators working in areas most likely to contain toluene. The badges, which use an active charcoal wafer as a collection medium, were desorbed with carbon disulfide and analyzed by gas chromatography. 1. PERSONNEL MONITORING As shown on Table 2 (Attachment 3) the personnel samples were well below the 100 ppm TLV-TWA. This agrees with historical data. See also Attachment 4. XYLENE EXPOSURE EVALUTION. .. Explanation of Guidelines and Sampling Method The ACGIH Threshold Limit Value (TLV-TWA) for xylene is 100 ppm with a TLV-STEL of 150 ppm. The TLV-STEL is a 15 minute exposure guideline.

The badges, which use an active charcoal wafer as a coll ction medium, were desobed with carbon disulfide and analyzed by gas chromatography 1. PERSONNEL MONITORING AS SHOWN ON TABLE 3 (ATTACHMENT 5) THE PERSONNEL SAMPLES WERE WELL BELOW THE 100 PPM TLV-TWA. This agrees with historical data. See also Attachment 6. 1, 3-BUTADIENE EXPOSURE EVALUATION Explanation of Guidelines and Sampling Method The ACGXH Threshold Limit Value (TLV-TWA) for 1, 3-Butadiene is 10 ppm. No TLV-STEL value was available. The TLV-STEL is a 15 minute exposure guideline. The 3M organic vapor monitor badge (#3500) was used to obtain breathing zone samples of operators working in areas most likely to contain 1, 3-Butadiene. The badges, which use an active charcoal wafer as a collection medium, were desorbed with carbon disulfide and analyzed by gas chromatography. 1. PERSONNEL MONITORING As shown on Table 4 (Attachment 7) the personnel samples were well below the 10 ppm TLV-TWA. This agrees with historical data. See also Attachment 8. NOISE EXPOSURE EVALUATION Method and Explanation of Guidelines A DuPont MK-2 Audio Dosimeter was used as a sound level meter to measure area noise levels. The dosimeter meets or exceeds all current requirements established by government agencies in the United States for personal audio dosimeters. All noise measurements were made using an 80 and 90 db(A) threshold level and a 90 db(A) criterion level. The threshold is the level that noise must exceed to be included in the dose calculation and the criterion is the decibel level that will yield a 100 percent dose in eight hours. The 90 db(A) criterion level is an OSHA regulation, to obtain the dose percent using the Louisiana Division criterion level of 85 db(A) the results were multiplied by 2 (two). This is true due to the 5 db(A) doubling rate that is included in both the OSHA regulations and Louisiand Division Standard. All of the audio dosimeters were calibrated before use with an Audio Dosimeter Calibrator at sound level af 94 decibels. LHC II Industrial Hygiene Report, 1987 July 13, 1988 Page 4 1. Area Survey As shown in Attachments 9 & 10, most of the plant is a high noise area (>90 dbA), especially around the turbomachinery. The entire plant is considered an ear protection area. High noise areas are posted with warning signs and these areas are communicated to employees in the annual Industrial Hygiene Safety Meeetings. SAMPLING STRATEGY PLAN FOR 1988 1. Noise Conduct area surveys following major modifications to the plant and while the plant is being shut-down and started-up. 2. Benzene, toluene, xylene, and 1, 3-butadiene Conduct personnel and area monitoring in our new waste water area. No other monitoring is considered necessay as indicated by historical data. ACCOMPLISHMENTS FOR 1987 AND GOALS FOR 1988 Hearing: Accomplishments in 1987: Investigated efficiencies of various types of hearing protection used in block and communicated this information to all employees. Redirected 60 pound steam muffler discharge to lessen noise expolure to personnel on road way north of plant. Goals for 1988 Investigate all new hearing protection available and communicate this information to employees. Asbestos: Accomplishments in 1987: Trained plant personnel on the dangers of asbestos at our Industrial Hygiene Training classes. Positively identified all asbestos in the plant and labeled all lines with asbestos warning label. Removed or encapsulated all damaged asbestos. Goals for 1988 Remove as much asbestos as possible and reinsulate with a non-asbestos material.
