LOUISIANA 70764-0160 604 3SB-SOOO A1 Baker cc: Arnold Seldule 3oe Granler Terry Campbell Introduction: Attached is the Environmental Health Survey and the 1982 Area Noise Survey for l^olyA. These surveys are being circulated to the Poly A 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 continue to 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 from the catalyst mix job had Isopar C concentrations above the Exxon Exposure Limit. k. None of the personnel breathing zone samples that were taken from the millwrights lap-room job had Isopar H concentrations above the Exxon Exposure Limit.

There was no SIO2 detected In the personnel breathing zone samples of O.T^s mixing superfloss. However, due to the mann r in which the superfloss is handled: a. The dust mask should continue to be worn while performing this Job to prevent possible overexposure to SiO^. b. Alternate methods of handling the superfloss should be considered to further reduce the possibility of overexposure to SI0.

Poche ENVIROhHENTAL HEALTH SURVEY - POLY A Consequences of Overexposure to Noise Prolonged and repeated exposures to noise levels above 90 decibels may cause severe damage to the nerves in the inner e&r. 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 Nineteen (19) 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 100%. POLY A 3ob Catalyst Mixer O.T.

Isopar C is Irritating to the eyes and skin. Prolonged contact with skin may results in the extraction of natural oils. Inhalation of high vapor concentrations may have results ranging from mild depression to convulsions and loss of consciousness. Exposure to Isopar C while mixing catalyst Eight (8) four hour breathing zone samples were taken from the catalyst mix ^ob. The average exposure to Isopar C was .6 ppm and the highest concentration detected was 1.5 ppm. Consequences of Overexposure to Isopar M The Exxon exposure limit for Isopar H is 300 ppm. This chemical is irritating to the eyes and skin. Also, prolonged or repeated exposures of the vapor may cause slight anesthesia and irritation o the respiratory passages. Isopar M should be used under the hood in the lap room. Also rubber gloves should be worn to prevent gross contact with the skin. Millwright Exposure to Isopar M Two (2) four hour breathing zone samples were taken from the millwrights using Isopar M in the lap room. The average exposure was 4.8 ppm and the highest concentration detected was 7.2 ppm. Consequences of Overexposure to Superfloss (S10?) The Threshold Limit Value (TLV) for Si02 is .1 mg/m^ respirable dust and .3 mg/m^ non-respirable dust. Long term or repeated exposure to high concentrations of SiO^ may cause pulmonary disease. A dust mask should be worn whenever handling Superfloss to prevent overexposure. Potential Exposure to Superfloss (SIO2) One (1) eight hour breathing zone sample was taken from the extrusion O.T. on a day when Superfloss was being mixed. The potential exposure ws <1 mg/m3 respirable dust and .2 mg/m3 non-respirable dust.

WHEN THIS OCCURS; THE HEMOGLOBIN IS UNAVAILABLE TO TRANSPORT OXYGEN FROM THE LUNGS TO THE REMAINDER OF THE BODY. PROGRESSIVE SYMPTOMS OF OVEREXPOSURE INCLUDE HEADACHE; DILATION OF BLOOD VESSELS t NEAR THE SKIN; THROBBING IN TEMPLES; SEVERE HEADACHE; WEAKNESS; DIZZINESS; DIMMED VISION; NAUSEA; VOMITING; COLLAPSE; INCREASED RE SPIRATION AND PULSE; COMA; CONVULSIONS; WEAK PULSE; SLOW RESPIRATION; RESPIRATORY FAILURE AND (ULTIMATELY) DEATH. CARBON MONOXIDE HAS NO IRRITATING PROPERTIES AND; THEREFORE; OVER EXPOSURE is not obvious. This has resulted in MANY FATALITIES.
