The New OSHA Respirable Crystalline Silica Dust Regulations Explained

According to the Occupational Safety and Health Administration, over two million construction workers a year are exposed to crystalline silica dust. Found in materials like concrete, tile, rock, stone and brick, exposure to silica dust can be a major cause of a fatal lung cancer known as silicosis.

As of September 23, 2017, the OSHA® regulation on respirable crystalline silica dust (29 CFR 1926.1153) is being enforced for construction trades. This regulation reduces the Permissible Exposure Limit (PEL) to 50 μg/m³ over an 8-hour period and will affect jobsites nationwide.

Milwaukee offers a full range of dust extraction solutions to allow users to be compliant with the regulation when using rotary hammers and grinders for the most common silica-producing applications.

Compliance Methods

Table 1

(Compliance through OSHA.’s Specified Control Methods)

Rotary Drilling / Chipping

Drill or chip with a commercial dust collection system. Filtration must have a minimum 99% efficiency and a filter cleaning mechanism.

Cutting / Grinding

Use a shroud that is attached to a dust extractor with a suction rate of at least 25CFM per inch of wheel diameter. The dust extractor filter must have a minimum 99% efficiency and a filter cleaning mechanism.

Objective Data

Data provided by the manufacturer that proves users are below the PEL (Permissible Exposure Limit) when using engineered control methods such as MILWAUKEE HAMMERVAC™ units or dust shrouds.

Self-Monitoring program

Employers may choose to collect dust with alternative methods. This can be time-consuming and costly.

If this option is chosen, employers must:

  • Purchase and utilize air quality monitoring systems.
  • Acquire test data from air monitoring systems.
  • Provide medical assessments for employees exposed to silica dust.
