The New OSHA Respirable Crystalline Silica Dust Regulations Explained

According to the Occupational Safety and Health Administrations, 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.

Starting September 23, 2017, the OSHA regulation on respirable crystalline silica dust (29 CFR 1926.1153) will be enforced for construction trades. This regulations 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 Information


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

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 filer must have a minimum 99%
efficiency and a filter cleaning mechanism

Objective Data

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.
