Question 4. There is a machine control switch aimed to be implemented on the wall, and used by three male and two female workers. The average shoulder height of three men is 105 cm. and two women is 97 cm. The switch is commanding two different machines at the same time. There is a problem of locating the switch to the most appropriate height for men and women workers. The noise levels of the machines are 130 and 138 decibels, respectively. The working environment is a wide and north-sided place. The job is a work with medium-weight and low-sensitivity. The walls are painted with two colors; white and orange, respectively, from the ceiling to the floor. General illumination level of the working environment is 1000 lux; and it is ensured by a few fluorescent lamps. a) Please comment on what should be the height of the switch by considering your anthropometry knowledge. b) What can you say about the noise level that the workers are exposed? What kind of solutions do you suggest to eliminate the harmful effects of noise? c) Please evaluate the working environment by considering visual environment and lighting. d) Please make recommendations about Ergonomics Program implementation in this company, based on the steps discussed in the video you watched in online classroom.
