1. “Ergonomics seeks to maximize safety, efficiency and comfort by shaping the work environment to the operator’s capabilities….” (Oborne, 1998 p8)
a) With reference to ergonomic approaches and examples, critically evaluate this statement, explaining what you understand by the term ‘ergonomics’, illustrating your answer with appropriate examples. (70%)
b) Explain, in detail, how the use of an ergonomic approach may contribute to the reduction of ‘human error’. (30%)
2. You are approached by Cool Cosmetics Ltd to design a new workroom to be used as an area for packing cosmetic gift boxes by hand. Gift boxes are to be packed with a variety of cosmetic products (shampoo, bodywash, sponge etc) by a team of eight operators (male and female) along a conveyor line. The assorted products, flat pack inner boxes and an insert card arrive on the conveyor and are packed into boxes by the operators. At the end of the conveyor, six gift boxes are placed in an outer box which is then put on a pallet.
a) Propose and justify, a design that will maximize the safety, efficiency and comfort of the employee. (70%)
b) Explain in detail, how you would investigate the effectiveness of the design in maximizing well-being of the workforce, with particular reference to MSDs, some months after the work room is operational. (30%)
3. a) Explain, in detail, the principles of LEV design to achieve effective control of airborne contaminants. (70%)
b) As the owner of a small garage premise, you wish to extend your activities to include the spraying of two-pack isocyanate paint products in a spray booth.
(i) Propose and justify an appropriate design for the spray booth. (15%)
(ii) Recommend additional controls in this instance, which may be appropriate to control exposure to isocyanates and protect workers’ health. (15%)
4. a) Explain in detail, the physiological mechanisms by which Noise Induced Hearing Loss occurs. (40%)
b) Appraise alternative methods for noise control which may be used to achieve occupational exposure standards for noise. (60%)
5. a) Distinguish between the characteristics of ‘active’ and ‘latent’ failures. (50%)
b) Describe and discuss the role of accident investigation in the management of occupational safety and health. (50%)
