Consider the case study: Tom has been named the manager of a large new chemical plant that is still to be designed and constructed. Toms responsibilities are to assemble and supervise the design staff; ensure that the plant is safe, operable, and maintainable, and start up the plant after construction. Tom considers recommending the design staff to choose ValCo valves to replace traditional gate valves for the new plant. ValCo valves are superior to traditional gate valves because they seal more tightly and more quickly. After a large number of ValCo valves have been ordered, Jim, the Valco salesman and a former classmate of Toms, visits Tom and gives Tom a pen with the company logo stamped in gold. The pen is worth $5. a) Determine the related items from the NSPE Code of Ethics. b) Construct a line drawing table to analyze the situation for which Tom accepts the pen. c) Should Tom accept the pen. Explain your answer in 34 sentences based on the analysis in part-(b).
