Silica Control in Construction.wmv (approximately 4 minutes); Georgia Tech’s Safety and Health Consultation Program - A brief introduction to common methods to reduce employee exposure to silica dust on a construction site.

Drywall Dust Engineering Control (running time approximately 7 minutes); CPWR -- Shows the use of a vacuum control to reduce dusts produced during drywall work using real-time monitoring.

Engineering Controls for Silica in Construction: Jackhammer; (2 videos running time approximately 10 seconds each); NIOSH – Shows a worker using a jackhammer to break concrete without a dust control and with a water spray dust control attachment.

Engineering Controls for Silica in Construction: Concrete Grinder; (2 videos running time approximately 7 seconds each); NIOSH – Shows a worker using a concrete grinder without a dust control and with a vacuum dust control system.

Engineering Controls for Silica in Construction: Cut-off Saw; (3 videos running time approximately 4 minutes, 6 minutes, respectively); OSHA – Shows a worker using a cut-off saw without a dust control and with water and vacuum controls.

Engineering Controls for Silica in Construction: Tuckpointing Grinder; (3 videos running time approximately 4 minutes and 7 seconds, respectively); OSHA – Shows a worker using a grinder without a dust control and with water and with vacuum controls.

Workers are the Experts (running time approximately 6 minutes); CPWR -- Shows how construction workers' ideas can improve safety and health on site. Features a vacuum system to reduce silica exposures during tuckpointing, as well as a safe bridge construction project, a crane mirror system, and ergonomic improvements on Boston's Big Dig.
