Brownsville Plant Ventilation Survey: Hood Evaluation Forms and Memo to K. G. Townsend (1978)

Twenty-two 'Industrial Hygiene Evaluation and Survey - Ventilation' forms dated 1/26/78 and 2/10/78 record hood type, dimensions and air-flow measurements for fume hoods and dust collectors at the Brownsville Plant. They are followed by a 2/14/78 internal memo to K. G. Townsend reporting the semi-annual ventilation survey and listing hoods below the 100 FPM recommended capture velocity. The first form (Insulation Shop band saw vacuum canister) remarks that the finer dust particles go through the bag and back into the room air.
