Upgrading Toronto's University subway line ventilation system
This paper presents the results of work undertaken as part of the Toronto Transit Commission's University Subway Line Fire Ventilation Upgrade Program. The design intent is to upgrade, to the greatest extent practical, the tunnel ventilation system to meet the current National Fire Protection Association (NFPA) 130 Standard for Fixed Guideway Transit and Passenger Rail Systems (TTC Fire Ventilation Upgrade Project Technical Criteria Report, Third Draft, 18 August 2005). The existing tunnel ventilation system is not fire-rated and does not have the necessary capacity for maintaining a smoke-free egress route in the event of any fire larger than a nuisance fire. The work has involved investigating the potential for both upgrading the existing fans and for installing new fans in existing blast relief shafts. During normal operating conditions the requirement for blast relief in order to alleviate the piston effect of trains is necessary. Hence the installation of fans in blast relief shafts would require that the fans are allowed to 'free wheel' when not in operation, allowing blast relief through the fans themselves.
