Four process units are in the plant. The units have FARS of 1, 0.5, 3, and 5, respectively. i) What is the overall FAR for the plant, assuming a worker exposure to all four units simultaneously? ii) What would be the overall FAR for a worker who spends 20% of their time in process area 1, 20% in process area 2, 4% in process area 3 and 20% in process area 4, assuming that the units are far enough apart that an accident in one would not affect the workers in another. What recommendation could be made based on the calculation of FAR in the two scenarios (I, and ii)? iii) The plant actually has a FAR of 4 and employs 2500 full-time workers in a process with average working hours of 45 hours per week. How many industrial-related deaths are expected each year considering 52 weeks per year?
