Principles of COSHH

COSHH is the law that requires employers to control substances that are hazardous to health. 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, however common substances such as paint, bleach or dust from natural materials may also be harmful.
