Welcome! • Parachute is a national charity dedicated to preventing injuries and helping Canadians lead long lives lived to the fullest. • For more information, please visit our website www.parachutecanada.org • Parachute is pleased to host a panel of Canadian experts discussing stair safety and the proposed changes to Canada’s National Building Code. • Please note that the views expressed during today’s presentations do not necessarily reflect those of Parachute. !

Our focus today is on a ! long overdue change now proposed for the National Building Code of Canada ! which is on a five-year ! revision cycle.! ! • Starting this month, until October 31, is the last! public review being done for the 2015 edition. ! • The change of concern is to Part 9 of the Code! where the current 210 mm (8.3 inch) minimum run! dimension for home stair treads—the worst among! English-language codes—will increase to 255 mm! (10 inches). This is still short of the 280 mm ! (11 inch) minimum run required by the Code ! for all other stairs. ! 3! Participating Effectively in the National Building Code Public Review Process to Support Improved Home Step Dimensions • Our purpose today is to provide a pan-Canadian opportunity! to broaden awareness of:! • Technical terms used for stairs and related ergonomics ! • The two most potent factors in stair safety—nominal step dimensions! and their uniformity! • Some epidemiology issues and insights! • How the process of Code development has lagged behind other model! codes and has failed Canadians! • How you can help us convince the Canadian Commission on ! Building and Fire Codes (CCBFC) to approve the proposed ! modification to the minimum run dimension for home stair treads, and! • Some ideas for advocating/encouraging the CCBFC to bring Canada’s! building codes for residential stair dimensions into line with current! requirements for non-residential buildings. ! ! ! • These requirements, found in international standards, ! ! call for minimum run dimensions of 280 mm (11 inches) ! ! and maximum rise of 180 mm (7 inches).! ! 4!

Following some thoughts on policy issues,! the two other presenters share insights they! have gained in working on task groups on ! stair and railing issues.

Participating Effectively in the National Building Code Public Review Process to Support Improved Home Step Dimensions (cid:3)There is more to understanding injury problems than epidemiology alone can deliver; the problems are complex, and such an understanding requires many different kinds of information, both quantitative and qualitative. . . . The field of ergonomics is based on this very principle, stressing the complex interactions among design, use, and injury potential . . . . The world is not tidy. . . . We cannot wait for precise quantification before we attempt to collect and use the information available to us. . . . We must be clear [that] our quest for scientific purity does not divert attention from the epidemic.(cid:4) ! ! Progress and potential in injury control. (Editorial) !
