Environmental samples were analyzed for total smoke dust, acetaldehyde (75070), methyl-formate (107313), acetone (67641), methyl-alcohol (67561), and isopropyl-alcohol (67630) at Yoder's Locker Plant (SIC-2077) Grantsville, Maryland, in January 1972. The survey was requested by an employee concerned over hickory sawdust and smoke exposures. Air samples were analyzed for total dust concentration and for the presence of thermal decomposition products of hickory sawdust. Sound level measurements were also taken. Medical evaluations were performed on some of the workers. Smoke dust concentrations ranged from 0.00 to 1.51 milligrams per cubic meter (mg/m3) which was below the concentration considered toxic, 15mg/m3. Air samples contained no detectable amounts of acetaldehyde, methyl-formate, acetone, methyl-alcohol, or isopropyl- alcohol. All noise levels were below standards. Symptoms of exposure to hickory smoke included eye and throat irritation and tightness of the chest. The authors conclude that workers do not suffer from residual effects from these exposures. However, the smoke house should be properly sealed and the ventilation system upgraded, capable of exhausting any buildup of smoke in adjacent rooms.
