Controlling Silica Exposure Using Table 1

Filed in Codes and Standards, Safety by on November 8, 2017 0 Comments

When working with materials containing silica, if you follow the requirements specified by the Occupational Safety and Health Administration’s (OSHA) Table 1 fully and completely, you will not be required to do air monitoring and will be assumed to be below the permissible exposure limit.

Table 1 matches common construction tasks with dust control methods. That way, contractors know exactly what they need to do to limit worker exposures to silica.

These resources have been pulled from multiple manufacturers and OSHA to help you comply with the silica rule that went into effect Sept. 23 and is now being enforced by OSHA.

Stationary masonry saws

Handheld power saws (any blade diameter)

Handheld power saws for cutting fiber-cement board (with blade diameter of 8 inches or less)

Walk-behind saws

Rig-mounted core saws or drills

Handheld and stand-mounted drills (including impact and rotary hammer drills)

Jackhammers and handheld powered chipping tools

Handheld grinders for uses other than mortar removal
