Subject
Ventilation Survey
The semi-annual Industrial Hygiene Survey of ventilation equipment at the Brownsville Plant has been completed. Flow measurements and evaluations were performed on 20 fume hoods and two dust collectors. Their locations in the plant are as follows:
Laboratory Welding Shop Machine Shop
Carpenter Shop Recovery Lab Reaction #1 Lab Reaction #2 Lab

The following are hoods which do not meet the 100 FPM recommended capture velocity or which merit special mention for other reasons:
1. The laboratory has the same 3 hoods as last year that require attention.
A. The bottlewashers hood has a capture velocity of 55 FPM, which is highly inadequate for the large amounts of chemicals which are dumped in the sink. The problem was turned over to Engineering last year, however no concrete developments have come about so far.
B. The E.P. A.A. bench hood also has 55 FPM with the door wide open, the flow is increased to 100 FPM with a 14" door opening, but it is not easy to work with so small an opening. No efforts have been made to correct this hood.
C. The chemicals bench east side hood has a flow of 60 FPM with the door wide open and it is always operated in this manner. Also the acetic anhydride distillation apparatus prevents the door from closing lower than 18" and if a chemical spill were to occur inside the hood, it could not be isolated by closing the door. No efforts have been made to correct this hood.
D. The two mini-labs were equipped with compensating type hoods and the air flows are excellent.
