The Workplace (Health, Safety and Welfare) Regulations 1992

These Regulations require that employers provide effective and suitable ventilation in every enclosed workplace. This includes kitchens, which need ventilation to create a safe and comfortable working environment. Catering and cooking can produce significant amounts of fumes and vapours, as well as large amounts of heat. Mechanical extraction, via a canopy hood installed over the cooking appliances, can remove these fumes and vapour and discharge them to a safe location.

The Health and Safety at Work etc Act 1974

The Act places duties on anyone in control of premises who makes them available as a place of work for others to take reasonable measures to ensure, so far as is reasonably practicable, that the premises, plant and equipment are safe and without risks to health.
