Emergency exits must be installed as required by local codes. This usually entails installing one-way swinging steel doors that swing into an office room during emergencies while a two-hour firewall rating is often built in to help stop or significantly slow fires. Human occupants of an affected area need a reliable means to leave and fire exit routes should provide sufficient escape options through unobstructed doorways leading from emergency escape zones out into fire-resistant corridors or safe exterior locations, such as outside the building on well-maintained roads where drivers are not operating motor vehicles with lights off.
