| Title |
| Silica Exposure (3 credit hours/3 HSW Hours) |
| Course Description |
| This 3 hour course is based on a modified version of OSHA training material related to protecting personnel exposed to crystalline silica in the workplace. Silicosis is a disabling, nonreversible and sometimes fatal lung disease caused by breathing in crystalline silica. Silicosis accounts for about 200 deaths in the U.S. every year. In the construction industry, the most severe exposures to crystalline silica result from sandblasting. Other activities that may produce crystalline silica dust include jack hammering; rock/well drilling; concrete mixing and drilling; brick and concrete block cutting; tunneling operations; cement and asphalt pavement manufacturing; setting, laying and repair of railroad track; and foundry operations.
