OSHA has identified four categories of hazards that account for more than 50% of all construction fatalities: Falls-(36.5%), Struck by object-84 (10.1%) , Electrocutions-71 (8.6%), Caught-in/between-21 (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:
1. What are the common causative factors?
2. What does data indicate?
3. What are the effective proven corrective measures?
BOS 3401, Construction Safety 4 Remember that a significant aspect of any research paper is the summary analysis by the writer of that research (in this case, you). The submission must be a minimum of three pages in length, not including the title page or reference page.
Develop an estimate of the volumetric flow rate of air that will be required for aeration of the mixed liquor in an activated sludge system.For this calculation, assume that the (ultimate) CBOD is 200 mg/L and (ultimate) NBOD is 50 mg/L.
Explain the relationship between check structure and turnout/outlet structure in terms of their operations/functions
What are the structural systems that the building uses? What challenges and opportunities will there be in replicating the structure? What are the challenges and opportunities offered by the site?
