Safely re-occupying buildings

As businesses start to consider bringing staff back into work premises, a number of issues need to be considered for the safety of everyone entering the building. Government guidelines should be followed.

This brief document is intended to give business owners, managers and employers an outline of the main areas that need to be considered concerning both safe working practices and the assessment of building services. It includes links to a new Health and Safety Executive (HSE) website on minimising the risk of legionella.
