Many businesses use standard household cleaning chemicals in the workplace. Employers have a legal duty to assess the risks to employees that handle and use these products if they have hazardous properties. This does not need to be an onerous task if only small quantities are used and stored in the workplace. A low-risk COSHH Assessment can be carried out utilising relevant information from the Material Safety Data Sheet (MSDS) and also including local procedures (e.g. where is it stored, what PPE should be worn and where to find it, what the emergency arrangements are if there is a spillage or accident). COSHH Assessments must be documented if five or more persons are employed.
