Seyfarth Synopsis: OSHA has just released several fact sheets applicable to industries regulated under the Crystalline Silica Standards in Construction Rule.

OSHA has recently released several silica dust fact sheets, including Controlling Silica Dust in Construction – Crushing Machines Fact Sheet (OSHA FS-3935 – 2017), Controlling Silica Dust in Construction – Heavy Equipment and Utility Vehicles Used During Demolition Activities Fact Sheet (OSHA FS-3936 – 2017), Controlling Silica Dust in Construction – Heavy Equipment and Utility Vehicles Used for Grading and Excavating Tasks Fact Sheet (OSHA FS-3937 – 2017), and Controlling Silica Dust in Construction – Large Drivable Milling Machines (Half Lane and Larger) Fact Sheet (OSHA FS-3934 – 2017).

The fact sheets reiterate OSHA’s position that when inhaled small particles of silica can irreversibly damage the lungs. The fact sheets describe dust controls that can be used to minimize the amount of airborne dust when using crushing machines and heavy equipment, as listed in Table 1 of the Respirable Crystalline Silica Standard for Construction. Specific engineering controls listed are “wet methods,” and “dust suppressants,” and “exhaust ventilation,” and “operator isolation” such as “enclosed cab.”
