Do my doors need to break out on a fire escape route?

This is dependent on individual building control authorities approach to the Building Regulations. The majority accept the doors being linked to an automatic fire detection system that opens the doors on activation of the fire detection system or failure of the power supply by means of a monitored battery back up system incorporated within the door operator. In certain instances break out may be required to achieve the maximum possible escape width as both side wings and doors break out.

How deep do I need to design my lobby to create an air lock?

appraisal of results

At least 3,000 mm is required between door sets to achieve any kind of air lock effect. However as the majority of entrances are designed for two way traffic it is unlikely that even a deep lobby would act as an effective climate control. An airlock device can be incorporated which prevents the two sets of door being opened at the same time. However we would only recommend installing such a device in trained traffic situations due to the high potential of traffic flow problems.
