A Ir Tx' \ . : m - \ Gay Rains removes filters in orde Clinton ft Clinton Mills conducts semi-annual dust monitoring to assure compliance with the Occupational Safety and Health Act. The company retains Texcon, Inc. of Greenville to perform the actual dust monitoring. A team of trained technicians visits each plant every six months and utilizes space age looking devices called vertirai elutriators to collect particles of cotton dust which measure 15 microns or smaller that may be present in a work area. The company, in most every manufacturing area, is within the OSHA permissible exposure limits that have been set for the industry. In yarn manufacturing, (opening to slashing), OSHA has set the P.E.L. (Permissible Exposure Limits) at .2 milligrams per cubic meter of air; slashing and weaving, .75 milligrams per cubic meter of air, and warehouse, wastehouse, and other areas, .50 milligrams per cubic meter of air. It is almost impossible to understand the small amount of dust acceptable under the standard. For instance, think about two grains of salt in a large refrigerator. This will illustrate what the "standard" would look like in yarn manufacturing areas. Texcon technicians, using their air sampling techniques and equipment, operate the elutriators for a minimum of six hours on each shift. The elutriators are located in strategic spots throughout the designated work areas. The equipment is designed to collect the smallest particles which are to be respirable. The elutriators also capture other harmless substances which may be present in the air during the sampling process. Each cone-shaped cylinder is attached to a support which places the end of the elutriatrtr at th<* I imiwi WIIV u i IIIV uppiu/vn i IQIC I ICIgl II U1 LIIC Emplo ?
