OSHA has identified four categories of hazards that account for more than 50% of all construction fatalities:

Falls (36.5%)
Struck by object (10.1%)
Electrocutions (8.6%)
Caught-in/between (2.5%)
The assignment is to write a research paper involving one of these four construction hazard categories. You may narrow your topic down to a more specific type of accident within the major category. For example, under falls, you could focus your research on falls from ladders. When writing the paper, consider the following questions:

What are the common causative factors?
What does data indicate?
What are the effective proven corrective measures?
