parts requiring cleaning are precision instrument bearings and assemblies containing beryllium. The principal solvents used for this cleaning have been 1,1,2-Trichloro 1,2,2-trifluoroethane (CFC-113) and 1,1,1-Trichloroethane (MCF). The Center has begun modifying its many cleaning processes to use known alternatives for these solvents.

Exposure Evaluation and Controls Exposure to beryllium via inhalation of airborne beryllium or dermal contact with beryllium-containing dust, fume, mist or solutions can cause health effects. The following resources provide information on exposure limits and analytical methods used to evaluate workers' beryllium exposure.
This includes regular cleaning, inspection, and repair of equipment to prevent leaks, spills, or other malfunctions that could lead to increased beryllium exposure. In addition to these measures, employers should also provide appropriate personal protective equipment (PPE) to further minimize exposure.
