Silica dust is what is produced when concrete, bricks, blocks, etc are cut, and while it might seem harmless, it contains crystalline silica. The existence of crystalline silica and the hazards it can cause to a worker’s body – silicosis, chronic obstructive pulmonary disease and kidney disease – has been known for decades. That is why Husqvarna Construction Products has been developing solutions to control dust for decades.

In the United States of America the National Health and Safety Regulations body (OSHA) has released the final ruling on crystalline silica exposure on March 23, 2016.It can be reasonably argued that the OSHA Silica ruling represents the best practices for handling exposure to crystalline silica dust. Complying with OSHA's silica rule will meet or exceed Australian OH&S requirements. Husqvarna is here to support you with information and products to assist with reducing crystalline silica dust exposure.

We always work towards finding the best solution for our customers – from both an efficiency standpoint and from a worker’s view. Following the US OSHA ruling you can significantly  minimise your exposure to crystalline silica dust.

CURRENT AUSTRALIAN STANDARDS        

The Australian standard for airborne crystalline silica states a mandatory limit of 0.1mg/m3 over an eight hour shift.

The OSHA crystalline silica rule §1926.1153 for the United States of America revises the amount of crystalline silica a worker should be exposed to:

The permissible exposure limit will be set at 50 micrograms per cubic meter of air, averaged over an eight hour shift.

Employers will be required to take measures to control silica, either through using water, dust collection systems, ventilation or providing respirators.
Employers will also be required to limit the amount of time a worker can be exposed to hazardous environments, write an exposure control plan, designate a competent person, offer medical exams to highly exposed workers and train workers on the risks and how to avoid silica dust.

By following the suggestions of the US OSHA standards you can further reduce your crystalline silica dust exposure to less than the current Australian standard.
