The Health and Safety (Display Screen Equipment) Regulations 1992 exist to protect desk workers from the health risks associated with using devices such as computers, laptops, tablets and smartphones (DSE) for extended periods of time.
Under the DSE regulations, employers have a duty of care to ensure their employees are set up to work safely in line with specific guidelines:
To carry out workplace assessments, including desk setup, equipment and furniture, for any employees who use DSE daily for more than an hour at a time
To provide training and information to help employees minimise the risks of DSE work and adopt safe working practices
