LOUISIANA 707S4-01S0 B04 3S9-SOOO cc: Arnold Seldule Doe Cranler Terry Campbell Introduction Attached Is th^T98^tnvlronmental Health Survey and the '1982 Area Noise Survey fo?~T*olv C. These surveys are being circulated to the Poly C plant personnel for training in: 1. The consequences of overexposure to chemical and physical agents in the plant. 2. The results of' the employee exposure measurements made in 1982. 3. The control measures available to minimize employee exposures. Conclusions: 1. Due to the large number of high noise areas in the plant: a. The hearing conservation program should be continued to prevent possible overexposure to noise. b. Engineering controls should be investigated to reduce the number of high noise sources. 2. None of the job classifications that were monitored for noise exposure had an average noise dose greater than the permissible noise dose. 3. None of the personnel breathing zone samples that were taken during the monitoring for Isopar C exceeded the Exxon Exposure limit 4. None of the personnel breathing zone samples that were taken during the monitoring for Dowtherm A exceeded the industrial hygiene guideline (IHG). 5. None of the personnel breathing zone samples that were taken during the monitoring for nuisance dusts exceeded the TLV.

It Is mandatory that ear protection be worn In any areas that have noise levels exceeding 90 decibels* "Ear Protection Required" signs are posted in these areas. Also the area noise surveys conducted this year are at the end of this report showing these areas* REMEMBER: Hearing loss caused from prolonged exposure to noise above 90 decibels is gradual and usually permanent* Don't lose your hearing, use the ear protection. Potential Exposure to Noise Sixty-six (66) tests were made for personal noise exposure using an audio dosimeter. The audio dosimeter integrates the noise levels over time to give a percentage of allowable noise exposure. For example, 90 db for 8 hours would equal 100Z.

Prolonged exposure to Isopar E vapors may cause slight central nervous system depression as well as irritation of respiratory passages. Exposure to Isopar E The Exxon exposure limit is 480 ppm for 8 hours. Fifteen 8-hour breathing zone samples were taken from 5 job classifications. The highest average concentration was 1.5 parts per million (ppm) detected on the O.T. job. One sample was taken from the O.T. while loading an isopar E truck.

Repeated or prolonged overexposure can cause failure of the sweat regulating mechanism (which cools'the body) which can result in heat stroke (high fever and unconsciousness, with possible death if not reversed immediately).
