Britain’s workplace safety regulator has published a helpful guide of do’s and don’ts for people installing stone worktops.
The Health and Safety Executive’s (HSE) guidance is designed to remind dutyholders and workers about the need to ensure that suitable procedures and controls are in place to help protect against exposure to stone dust and prevent workers breathing in respirable crystalline silica (RCS).
Stone workers are at risk of exposure to airborne particles of stone dust containing RCS when processing stone, including engineered stone, by cutting, chiselling and polishing. Over time, breathing in these silica particles can cause irreversible, life-changing and often fatal respiratory conditions such as silicosis, chronic obstructive pulmonary disease and lung cancer.
HSE’s guidance covers: Competent staff & effective processes, Pre-Installation, On-site Installation, and Post-installation.
Here are just some of the important steps that can be taken to minimise the risk of exposure:
Installers should understand the risk from processing stone and how to use suitable controls;
Worktops should be pre-fabricated so further processing on site is avoided;
Water suppression or on-tool extraction with shroud and dust collector attached to an M-class vacuum should be used to control any dust generated;
Respiratory protective equipment with an assigned protection factor (APF) of at least 20 (e.g. FFP3 face mask) should be worn when processing the stone
Cleaning should be by wet methods or dust class M vacuum to prevent creation of dust.
