Frequently Asked Questions
What is a COSHH assessment?
A COSHH (Control of Substances Hazardous to Health) assessment identifies hazardous substances on your project, evaluates the risks, and sets out control measures to protect workers. It's a legal requirement under COSHH Regulations 2002.
How does the AI know which substances to assess?
Based on your scope of works and trades involved, the AI identifies common hazardous substances — cement dust, solvent-based products, adhesives, paints, silica dust, etc. You can also add specific substances manually.
Are these assessments legally compliant?
Yes. Each assessment follows the COSHH Regulations 2002 format and includes all required information: substance identification, exposure routes, health effects, risk ratings, control measures, and emergency procedures.
Can I generate assessments for specific products?
Yes. You can add specific product names and the AI will create assessments based on the known hazards of those products.
Do I still need to check safety data sheets?
For specific branded products, you should always verify against the manufacturer's safety data sheet. The Site Book gives you a solid foundation that covers the common hazards for your type of work.
