The lab report dated Karen 25,1974 shews a count of 2.4 fxcies/cc higher than the TLV of 2 fiores/cc. Tr j dry mix discharge from "Lodige" is provided with a down draft rec tangular hood 36" x 8" exhausting at the rate of 400 cfm. t form Kachines: The two preform machines are provided with hoods for do .ping and loading operations. These hoods are 18" x 9" each exhausting at the rate cf 900 cfm. However, there is no hood for weighing and hand scooping. The me" working at these machines wear respirators. The fibre counts at t)ese machines have been low. .`tolling machines: There is no local mechanical exhaust for dumping of mix j.1 to tne nopper for the rolling machine. A small amount of asbestos dust .as found to be disseminating into the general area. A new hand roll machine was in operation during the visit. According to tor.
