Q1. What is a hazard? (1) Q2. What is the purpose of the hazard identification/risk assessment process? (2) Q3. What are the 9 GHS classifications for hazardous chemicals? (1) Q4. Excluding HAZOP, name 3 other types of hazard identification procedures. (3) Q5. Q6. Categorise the following control measures. a) Heat resistant gloves for furnace work. b) Using sodium percarbonate for cleaning instead of sodium hydroxide. c) Installation of a pressure relief value. d) Use of water-based paints instead of solvent based. e) Implementation of a standard operating procedure. (5) A 8m x 6m x 2.7m laboratory has CO2 cylinder (31kg liquid CO2) stored inside of it to be used for small lab scale experiments. a) If the failure rate of the regulator fitted to the cylinder is 107/hour, what is the likelihood rating given for full failure of the regulator? b) If the regulator was to fail, what would the consequence rating be? Explain your reasoning. c) What is your overall risk rating? d) What control measures would you implement to lessen the overall risk rating of storing a CO2 cylinder in the laboratory? (8) Q1.
