OSHA’s respirable crystalline silica standard requires employers to use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the PEL, unless the employer can demonstrate that such controls are not feasible. What are some controls an employer can implement to reduce employee exposure to silica? 

Discuss whether you think OSHA’s air contaminant standards are important, and why. Do you think they are adequate to protect employees from airborne contaminant hazards in the workplace? Explain.
