Chairs
Analyzed the strength of various chairs. These analyses included evaluating
manufacturing and design flaws. In some cases tipping stability was a
consideration.
Electrically Operated Doors
Analyzed the control systems and the actuating means for various doors.
Powered over-head doors have been studied extensively.
Lawn Mowers & Weed Eaters
Testified regarding guards for lawn mowers and the potential for mowers and
weed eaters to throw debris which injures operators and nearby people. The potential for powered lawn mowers to move from neutral into a powered gear has been an issue.
Ladders
Analyzed ladders that slipped sideways and fell or collapsed. The ladders
were both aluminum and wood.
Saws
Analyzed metal and wood cutting saws. The objective was to assess the guards to determine whether they satisfied established standards. Often the issue of 'kick-back' was part of the analysis.
