2) SMOKE EVACUATION IN ERP (PREMISES WITH PUBLIC ACCESS)



The legal safety provisions for public access buildings are defined within ‘Safety rules regarding the risk of fire and panic in ERP’, with distinct smoke evacuation rules:

For premises under 1000m², the usable area of the building relates to 1/200 of the floor area. For premises over 1000m²: the usable area of the building is defined by the IT 246 calculations. Premises over 2000m² will be divided into sectors of not over 1600m² for smoke evacuation. The length of a sector must be no greater than 60m.
