Escape routes are a key consideration for any design. They need to be suitably located, sufficient in number and ensure they are protected and adequately lit.
In relation to fire rated partitioning, screens and doors, your design will depend on the level of fire safety you require – for example, if you only have 1 escape route, you may need 2 hours of fire protection, whereas if you have 2, you may only need 30 mins or an hour.
It is also important to mention that different sectors have different safe fire escape distances, along with how many fire exits there are from the building. Read document B for more details on this.
