HSE has refreshed its guidance publication ‘Health surveillance for those exposed to respirable crystalline silica’ G404.
The publication has been refreshed to emphasise:
- where workers are regularly exposed to RCS dust and there is a reasonable likelihood that silicosis may develop
- worktop manufacturing and installation are stated as high-risk occupations and provision of health surveillance must be considered
- health surveillance is a risk-based scheme of repeated health checks and is required under the COSHH Regulations for those exposed to hazardous substances to detect ill-health effects early and show whether review and revision of risk assessment and control measures are necessary
- occupational health professionals should be consulted to identify when additional health surveillance is needed, for example where over-exposure to RCS dust has already occurred
You can read the updated publication: Health surveillance for those exposed to respirable crystalline silica (G404).
