Senra FROM Kiewstgad j )OATH jsJ4ay 14, 1977 SUBJECT New Pans in Polymer Effect 27 Yfl] Introduction The purpose of this study was to show the effect tbVlnstallfttUSh of new fans, on the second floor of the Polymer Building, has bad on the vinyl chloride (VCl) levels. Three old fans on the east wall were replaced with new fans, after April 4th and before May 8th, as follows: 1st fan from the south and 1st and 2nd fans from the north. Discussion I. *nje data before and after new ventilation Is shown below: April 4, 1977 (8-4 Shift) Before Sew Ventilation My 8, 1977 (8-4 Shift) After New Ventilation Mean, ppm VCl High, ppm VCl Low, ppm VCl Sample Points 234 23.6 33.5 31.4 36.8 41.5 40.6 6.3 12,8 16.0 5 26.4 39.2 10.8 2 21.7 Sample Points 345 '15.5 13.0 114.0 28.8 25.6 21.8 23.3 10.1 2.3 3.2 6.6 Standard Deviation 9.3 9.0 6.2 7.8 % Reduction in VCl -- -- -- -- 5.3 7.9 6.6 53.7 5.7 58.6 4.9 47.0 Humber of 15 Min* V Samples below 100 0 10 ppm VCl 0 4 97 Sample Point 2 -- Outside control room door Saaple Point 3 * by Reactor 3H Sample Point 4 by Reactor 313 Sample Point 5 -- by Reactor 315 Except for Sample Point 2, there was a significant reduction in Yd levels as a result of the ventilation. Rev Fans In felyner ~" Effect on TCX levels -2- H. The flov of air fra* the south end of feigner to the north end in shovn in Qreptos 1, 2, 3 sod U* There was a more definite pattern of air flov fro* the south end to the north end before the nev ventilation than after the nev ventila tion installed. Conclusions As a result of the nev ventilation: 1. The TCI levels In the north end of the building were significantly reduced. 2. The VC1 levels in the south end reaalned shout the sa*e. Additional ventilation would half here. 3* The VC1 levels in the entire second floor are still over 10 be* TCI nost of the tine and still higher than experienced aoet of last year. 4. The air in the south end was being polled to the north end before the new ventilation was Installed which probably helped to raise the TCI background in the north end. 9. The doers and windows on tbs north, south and east sides of tbs feigner Building are not closed at all tines. This Is considered necessary far the nost efficient operation of our Resent ventilating systa* and should reduce Td levels. Ventilating to reduce TCI does not correct the source of the emission. The fallowing ere ooneldered to be sane of the rntjaat sources of emissions which need to be end should be corrected ns soon as possible. Upstairs feigner* 1.
