The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Task Demand and Effects on Safety and Health: A New Perspective on Pre-task Planning

Tuesday, May 17
1:00 - 2:15 p.m.

When overall task demand exceeds capabilities, performance degrades, quality suffers, and exposure to health and safety hazards increases. This session will introduce the Task Demand vs. Capability model and discuss how to incorporate the lean construction concept to identify and address work factors that increase workers’ task difficulties and impact their overall performance. In line with the Prevention-through Design (PtD) concept, this session will conclude by discussing how to apply effective interventions and work practices to alter work processes to eliminate or mitigate such factors.
