Preliminary Survey Report: Control Technology for Manual Transfer of Chemical Powders at SCM Glidden Coatings and Resins, Huron, Ohio

摘要

A preliminary survey of control technology for the manual transfer of chemical powders was conducted at SCM Glidden Coatings and Resins (SIC-2851), Huron, Ohio in May, 1985. The manufacturing process used local and general exhaust ventilation to remove or dilute potential air contaminants generated during batching, loading, and mixing operations. The mixing operations were enclosed and highly automated. The ventilation system design appeared to be based on the American Conference of Governmental Industrial Hygienists ventilation manual. Workers were encouraged to use good work practices. They were provided with instruction when hired and received updates and reinforcement as needed. Incentive programs were used to maintain a high degree of motivation. Employees were given preemployment physicals and periodic medical examinations once hired. Periodic atmospheric dust monitoring was performed. The only personal protective equipment required was safety glasses with side shields. Respirators were not required as airborne dust concentrations were low, only 20 percent of the threshold limit value as shown by company data. The authors conclude that the facility is a well designed and operated manufacturing operation. An in depth survey of control technology at the facility is recommended.
