This J.A.Reinhardt Company and the IUP Research Institute propose to utilize an existing 5-year old health and safety management system coupled with current and proposed engineering controls as the foundation for reducing workers' beryllium concentration to less tha 0.100 micrograms per cubic meter of air during machining and other processing. During Phase I, JAR and the IUP Research Institute will develop a plan to verify preliminary data from this system, identify potential improvements to the HSMS and validate its' effectiveness in reducing Be concentration
