Your requirements
You must make "effective and suitable provision" that every enclosed space in your school is ventilated by "a sufficient quantity of fresh or purified air".
This is set out in regulation 6 of the Workplace Health, Safety and Welfare Regulations.
What does this mean?
Ventilation is the process of bringing fresh air into a building and removing poor-quality air.
The National Engineering Policy Centre describes 2 ways of doing this: natural and mechanical.
Natural ventilation includes windows, doors, air bricks and vents.
Mechanical ventilation uses fans and other technology to bring in fresh air and remove stale air.
It’s likely your school uses a mix of natural and mechanical ventilation depending on the type of space.
Air conditioning isn’t ventilation, as it circulates the same air instead of bringing in new air.
Keeping your school well-ventilated has a lot of benefits for pupils
