Crystalline silica is a naturally occurring substance used in many industries, from construction to food manufacturing to the production of glass and water and sewage treatment. Exposure to silica dust is linked to an increase risk of developing lung cancer and silicosis. OSHA has required standards to regulate exposure. The multimedia video goes over these regulations and demonstrates the engineering controls to help reduce exposure, as well as work practices employees can use to reduce their risk. Respiratory protection is covered in this training. Certain types of job tasks require different types of protection while working with the material. The training also goes over Table 1 of the Construction Regulation that OSHA has set up. Use this safety training to help employees prevent exposure to silica dust.
