This leads to the conclusion that some funding should be reallocated to construction safety. Studies of older workers are conflicting. On the Denver Airport project, older workers had higher injury rates, decade by decade. A Scandinavian study showed that VO2 max was s better predictor than age of injury risk. Older workers may have additional health problems that can, among other things, delay the healing process.
Different studies suggest greater or less accidents in the older worker.
It was suggested that the older worker claims were sometimes more complicated. The minorities in Oregon tend to be from Latin America and Russia. An example was that Latin American workers may learn more effectively from group discussion than from lectures. There is more technology that reduce the strength issues that used to limit women in construction. There is better training and especially better ergonomics.
