The occupational use of nanomaterials is regulated under the Control of Substances Hazardous to Health (COSHH). COSHH is the law that requires employers to control substances that are hazardous to health and includes nanomaterials. You can prevent or reduce workers' exposure to hazardous substances by:
Most businesses use substances, or products that are mixtures of substances. Some processes create substances. These could cause harm to employees, contractors and other people.
Sometimes substances are easily recognised as harmful. As a new technology, the risks of exposure associated with nanomaterials are not currently fully understood. Whilst knowledge gaps exist, HSE recommends a precautionary approach to risk management with control strategies aiming to reduce exposure as much as possible.
