Goals of Presentations and Discussions
By the end of the session you will have
A. A clear appreciation of how big theproblem of stairway safety and usabilityis relative to other problems addressedin building codes.
Section 3, Terminology and Epidemiology, deals with this,as does Section 4, Economics and Ergonomics.

Potential Contributing Factorsfor Recent Growth of Injuries
(1) Relatively steep stair step geometry permitted traditionallyonly for homes.
(2) A systemic top-of-flight dimensional non-uniformity onmany home stairs, due to flawed code requirementsand/or flawed construction and inspection practices.
(3) An apparent reduction—generally—in the codeenforcement process for new home construction.
(4) the potential deterioration of movement performance inthe US population (among others), stemming fromreduced physical activity and increasing prevalence ofobesity and overweight.
(5) Increased use of ʻType IIʼ handrails for new home stairs.(6) Increasing differential between public and home
stairways.
