  • NSAA Ski Lift Safety Fact Sheet
    CONTACT: Adrienne Saia Isaac Director of Marketing & Communications [email protected] (720) 963-4217 office UPDATED: December 2018 NSAA Ski Lift Safety Fact Sheet In the 2017/18 season, ski lifts and aerial tramways transported a total of 53.3 million skiers a total of 200 million miles. The last guest fatality resulting from a mechanical malfunction of a ski lift occurred in the 2016/17 season. Since 2004, there have been three fatalities resulting from falls from chairlifts unrelated to mechanical malfunctions. A passenger is five times more likely to suffer a fatality riding an elevator than a ski lift, and more than eight times more likely to suffer a fatality riding in a car than on a ski lift. Lift maintenance, safety and operation is governed by ANSI B77 and regulated in many states by a state agency. Overview Aerial ropeways (including lifts, trams, and gondolas) remain one of the safest methods of transportation. Ski areas across the United States are committed to lift safety and have an excellent safety record for uphill transportation as a result of this commitment. There is no other transportation system that is as safely operated, with so few injuries and fatalities, as the uphill transportation provided by chairlifts at ski resorts in the United States. Methodology & Terms NSAA compiles lift incident information and updates this Ski Lift Safety Fact Sheet annually to provide ski areas and the public with the most current information on the ski industry’s commitment to overall lift safety, financial investment in lifts and lift maintenance, industry education and training on lifts, and frequently asked questions about chairlifts.

  • Cable Car Safety Memo
    Trafikkontoret Cable Car Gothenburg: Cable Car Safety Memo Maj 2016 www.goteborg.se CABLE CAR GOTHENBURG: CABLE CAR SAFETY MEMO MAJ 2016 INTRODUCTORY REMARK In the continuous work with investigating urban cable cars, the issues of safety and security have been lifted. Since Swedish experience is scarce within the field of urban cable car systems this report makes a global outlook on risk and safety for cable cars, as well as a compilation of European regulations. Also the effects environmental conditions may have on cable car systems are presented, and how these risks can be minimized. The last part of the report covers passenger evacuation, which we have noticed is a subject of great interest to both the public and professionals in Gothenburg. The report was produced during the spring of 2016 by Koucky & Partners AB, Gothenburg, in cooperation with zatran GmbH, Dornbirn, Austria. All facts and conclusions are their own. The Urban Transport Administration and Västtrafik AB (the regional public transport company in West Sweden) will use the report in ongoing planning and investigations. The City of Gothenburg has through the Urban Transport Committee since 2013 investigated cable cars as a part of public transportation in Gothenburg. If cable cars were to be included as part of the public transportation system, this would be the first addition of a new transport mode for public transport in Sweden since the opening of the subway in Stockholm in the 1930’s. The publicly owned company Göteborg & Co was in 2009 commissioned by the municipal executive board to investigate how the city’s 400 anniversary in 2021 could be celebrated.
