Working Safely with James Hardie® Products
Why is managing silica important?
Silica (SiO2) is the second most common mineral in the earth's crust. It is a common ingredient in many stone products like concrete, brick, slate, and is included in fibre cement materials such as James Hardie® products. In an intact state, these products do not pose a risk. However, when cut, drilled, or abraded during installation, the resulting silica-containing dust can pose a potential health hazard.
To protect workers from potential health effects, the HSE under the COSHH Regulations has set a Maximum Exposure Limit (MEL) for respirable crystalline silica (RCS). Any exposure above this level will mandate the installer to take additional protective measures.
James Hardie encourages you to make every effort possible to minimize dust exposure levels. In any situation, properly-fitted approved respirators should be used in conjunction with the proper tools and cutting methods to further limit silica dust exposures, providing a safer workplace.
