OU2o/i fi2c
On October 25, 1979, a study was conducted at tbe new calender to determine employee exposure to vinyl chloride..
Procedure;
Samples were collected by means of an air transfer pump manufactured by Calibrated Instruments, Inc., Ardsley, N. Y. and their multi layered sample collection bags. Each sample represents a sample time period of 15 minutes. The bag samples were then analyzed by means of the R&D gas chromatograph. N.D. represents non-detectable results for vinyl chloride.
Monitoring Results of the Baa Samples are as Follows:
Bag No. 4
Location-Activity
Sample taken while walking directly in front of the windup.
PPM Level VCM
N.D.
13 Sample taken at banbury mill at
approximate area of mill operators
breathing zone.
N.D.
10 Sample taken at calender feed mill
at approximate area of mill operators
breathing zone.
N.D.
28 Sample taken of enclosed platform area
above calender rolls -- mill side of
calender rolls.

In addition, a sample of the 9300 type resin being utilized was brought back and analyzed by R&D. The result was 18.7 PPM R.V.C.M. The resin is produced by the Perryville Plant.
