The ventilation systems at Delfont Mackintosh Theatres (DMT) have been assessed and modified where
necessary to comply with current government guidelines and the Chartered Institute of Building Services
Engineers (CIBSE) Covid‐19 Ventilation guidelines.

In public areas:

• Ventilation systems are set to 100% fresh air.
• Ventilation of auditoria begins at least two hours prior to performances and carbon dioxide levels are monitored and controlled.
• Toilets are ventilated 24 hours a day and where possible, windows are open before, during and after the performance.

DMT will keep these measures under review in line with any changes to guidance or regulation.
