II. ACETONITRILE (OSHA PEL - 40 ppm. 8-HR TWA)
One 3114 operator was monitored for full-shift acetonitrile exposure while sampling and filling dryer, drumming tars and changing dryer filters. The result of this monitoring was 3.98 ppm.
III.
FORMALDEHYDE (OSHA PEL - 0.75 ppm, 8-HR TWA; OSHA STEL - 2.0 ppm, 15-HIN.TWA)
A polymer chemicals laboratory operator was monitored for short-term exposure to formaldehyde during extrusion of a 3114 sample. Three 15-minute monitorings were completed using passive diffusion badges from Air Quality Research Company. The results were 0.35 ppm, 0.83 ppm and 0.49 ppm. Although these exposures are below the STEL, it is still
recommended that spot ventilation be used during the extrusion test since formaldehyde is known to cause eye, nose and throat irritation at very low concentrations.
BFG-495&-E MID Ptintmg Co.. Henry, m. 6153/
NOC 14681
One back end 3114 operator and one front end operator were monitored for full-shift formaldehyde exposure during 3rd quarter. The monitoring results were 0.03 and 0.02, respectively. These latest results continue to agree With prior year's monitorings that there is no excessive exposure to formaldehyde in the 3114 process building over the fullshift. Additional short-term monitorings during premix make up are being taken.
XV. TOLUENE (OSHA PEL - 100 ppm, 8-HR TWA)
One operator from each of the following job classifications was monitored for toluene exposure and all results were below 1 ppm: X-70 operator, 06TS operator, crude building operator, MBTS operator and PC maintenance (working on vacuum distillate receiver).
V. CYCLOHEXANONE (OSHA PEL - 25 ppm, 8-HR TWA)
One polymer chemicals laboratory operator was monitored for cyclohexanone exposure. The monitoring result was 0.06 ppm.
VX. MERCURY (OSHA PEL - 50 mg/M1, 8-HR TWA)
One wastewater treatment technician was monitored for exposure to mercury vapor using a hopcallte tube and a monitoring pump. The exposure result was 4.3 mg/M3. There were no mercury compounds or elemental mercury in use at the time of monitoring. Monitoring for mercury vapor in the labs is being done on a spot check basis to determine if there is any exposure due to breakage of thermometers and mercury spills that have occurred in the past.
VII. ASBESTOS (OSHA PEL - 0.2 fibers/cc, 8-HR TWA)
Although no plant employees are involved with the handling or renovation of asbestos containing materials (ACM), some ACM still remains in certain work areas mainly as pipe insulation. In order to verify that asbestos exposure is not occurring due to the presence of ACM in these areas, area monitoring samples were taken on the 1st, 2nd, and 3rd floors of polymer chemicals building (712), the crude building (711), and gas fired boiler house (719). The results of all monitorings were less than 0.01 fibers/cc.
VIII. VINYL CHLORIDE (OSHA PEL - 1 ppm. 8-HR TWA)
During the third quarter of 1992 there were 39 monitorings completed for vinyl chloride exposure (22 poly/17 dryer). Of the total monitorings, none exceeded 1 ppm and 34 (87%) were below 0.5 ppm. These exposures are summarized below:

IX. MEDICAL SURVEILLANCE SUMMARY
Total number of Examinations - 59
Number of Examinations which showed:
a. Hearing loss - 3 b. Report by Department
PVC - 1 (not confirmed, to be retested) PC - 1 (not confirmed, to be retested) PC Maintenance - 1 (not confirmed, to be retested)
Follow-up Activities:
1. Send letter to each employee stating they have a S.T.S.
2. Retest each employee within 21 days. 3. Reinstruct each employee in the proper use of
hearing protection. 4. Reevaluate their working area.
X. PEL EXCEEDENCE INVESTIGATIONS
There were no exposure exceedences that occurred without protective equipment during the third quarter.
