Industrial Safety Summer 2013 Problems MEPdeF - 05/22/2013 Problem 1 : There are six process units in a chemical plant. The FARs for the units are given as follows: Process Unit 1 2 3 4 5 6 FAR .01 .05 .15 .30 .65 .85 Calculate: 1.1 The overall FAR for the plant. 1.2 If a worker A spends 10% of the time in Unit 2, 15% in Unit 3, 30% in Unit 5, and the rest in Unit 1. What is the overall FAR in this case? In worker B spends 10% of the time in Unit 1, 35% in Unit 3, 10% in Unit 5, and the rest in Unit 4. What is the overall FAR in this case? Which worker is at most risk? Why? 1.3 If there are 1000 workers in the plant, calculate the fatality rate for the whole plant. 1.4 Calculate the fatality rate for worker B, assuming that 45% of the total workers follow this shift. 1.5 If in Unit 5 the number of lost workdays has been 2 in the past 120 days and the total workers in this Unit are 250, find the OSHA Incidence Rate based on lost workdays. Solution: 1.1 The overall FAR for the plant. Plant FAR = 01 . 2 85 . 0 65 . 0 30 . 0 15 . 0 05 . 0 01 . 0 ) FAR ( 6 1 i = + + + + + = 1.2 If a worker A spends 10% of the time in Unit 2, 15% in Unit 3, 30% in Unit 5, and the rest in Unit 1. What is the overall FAR in this case? In worker B spends 10% of the time in Unit 1, 35% in Unit 3, 10% in Unit 5, and the rest in Unit 4. What is the overall FAR in this case? Which worker is at most risk? Why?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
