Control of Substances Hazardous to Health Regulations 2002

Under the Control of Substances Hazardous to Health (COSHH) Regulations, employers must assess and control the risks from any hazardous substances used at work. This page brings together Riverdale Falls’ COSHH risk assessments for key products such as coatings, waterproofing systems, cement-based materials, fuels and sealants, so that workers can quickly find the information they need.

Each accordion section summarises the hazards, routes of exposure, required PPE, safe-use instructions, and first-aid measures for a single substance. You can expand the relevant COSHH assessment to read it online, and use the PDF download link at the bottom of each section if you need a printable copy for site folders, inductions or job briefings.
