DOW CHEMICAL U.S.A. January 6, 1983 Jim Heaslip LOUISIANA DIVISION P O BOX ISO PLAQUEMINE. LOUISIANA 70704-0160 004 389-8000 cc: Arnold Seldule Joe Granier Terry Campbell Introduction; Attached Is the 1982 Environmental Health Survey and the 1982 Area Noise Survey for CPE. These surveys are being circulated to the CPE 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 presence 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 high noise sources. 2. None of the Job classifications that were tested for noise exposure had an average noise dose greater than the permissible noise dose. 3. Due to the high concentrations of non-asbestos form talc detected in the breathing zone samples of personnel working in the talc room: a. The dust mask requirements for the talc room should be strictly enforced to prevent overexposure to non-asbestos form talc. b. The new weigh feeder system should be installed as soon as possible to reduce the amount of talc that Is being released into the talc room. Mark D.

When this happens, hearing is first reduced in the high frequency range and will eventually be reduced in the normal speech range. Preventing Hearing Loss Ear plugs and ear muffs are two types of hearing protection available to you. Both types reduce noise exposure significantly to prevent hearing loss. Keep in mind as with all protective equipment, hearing protection is useful only if it is worn and worn properly. 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 Fourteen (14) 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.

The TLV was set to prevent any change in the lung function. Four samples were run on CPE O.T.'s while working in the talc room. The average potential exposure was 24.7 mg/m3 respirable dust and 29.5 mg/m3 non-resplrable dust. A new weigh feeder system has been ordered for the talc room which should / reduce the potential for overexposure to talc substantially. , ...
