- (a) Construct an event tree of the desired protective system and use it to calculate the frequency of a rupture of the low pressure storage vessel. (12)
(b) It is proposed that in addition to the protective system used for part a, the low pressure storage vessel is also fitted with a suitable pressure relief valve (reliability 0.9). Assuming that the vessel would only rupture if both the protective systems and the pressure relief valve failed at the same time, calculate the frequency of rupture of the low pressure storage vessel in these circumtances. (4)
(c) Outline the issues that would need to be considered when deciding whether both protective systems were needed on the low pressure storage vessel. (4) - In relation to the improvement of health and safety within organizations, describe what is meant by:
(a)
(1) corporate probation (2)
(2) adverse publicity orders (2)
(3) punitive damages (3)
(b) Outline how the international labour organization can influence health and safety standards in different countries (7)
(c) Outline how legislation may improve health and safety in the workplace (8) - (a) Explain the objectives of:
(1) active health and safety monitoring (5)
(2) reactive health and safety monitoring (5)
(b) Outlinr five active health safety monitoring system (5)
(c) Outlinr five reactive health safety monitoring system (5) - Outline the desirable design features of controls and displays on a control panel for a complex industrial process aimed at reducing the likelihood of human error (20)
