All employees working in the Paco Division of this plant are not considered exposetdo excessive asbestos in air concentrations This is based on the current health standard However if our judgment was based on the health standard effective July 1 1976 the dry texture filler would be considered exposed to an excessive amount of concean irtcr onacetntiraotinonss 2. The exhaust ventilation on the dry texture bagging machine is ineffective RECOMMENDATIONS 1. The local exhaust ventilation on the dry texture bagging machine be redesigned so that dust can be effec- tively captured and removed of 2 The operator the dry texture bagging machine should be provided with coveralls as much of this dust is infiltrating his street clothes This increases his chance for taking asbestos fibers home and exposing other members of his family 3 The ceiling texture mixer dry texture mixer and ready mixer should wear the appropriate dust masks that have been provided for them whenever they are dumping bags of asbestos Even though local exhaust ventilation has been provided at these dumping stations 150 linear feet per minute the actual dumpinogf asbestos does create turbulence and dust which oftens billows into the operator's face before being exhausted KMX 00581 RECOMMENDATIONS continued air hoses to clean off their are still using fibers into the 4.
