CHE3109 – Nov 2005 - Question 1 Solution a) Describe the control measures that might be applied to deal with a toxic hazard. List the measures in decreasing order of desirability – the hierarchy of control. Explain why engineers apply the control measures in this order. (10 marks) b) Discuss the main control measures that you would expect to be applied in the case of chlorine for the plant described here? (5 marks) c) This plant operates under elevated pressure and the absorber V02 will be protected by a relief valve. What considerations will be taken into account when determining the size and position of the valve? How would the discharge from the relief valve be dealt with? (10 marks) d) Would you consider this plant to have a high degree of inherent safety? Discuss. (X marks) a) Control measures in decreasing order of desirability – the hierarchy of control: Specification Substitution Containment Ventilation Reduced time of exposure Protective Equipment In designing a process, an engineer or scientist should aim for control measures at the top of the hierarchy. Only as a last resort should the measures lower down in the hierarchy be used.

    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.
