City Guilds Model Questions Vol1 2021 Engineering Question 20
Practice objective / multiple choice question 20 from the 2021 City Guilds Model Questions Vol1 Engineering examination.
A workshop risk assessment lists three hazards with the following annual probabilities and severity ratings (on a scale of 1-5):\n\n- Electric shock: probability = 0.02, severity = 5.\n- Fire: probability = 0.01, severity = 4.\n- Chemical spill: probability = 0.03, severity = 3.\n\nThe risk rating for a hazard is defined as probability × severity. The overall risk rating is the sum of the individual ratings. Safety policy requires the overall risk rating to be at most 0.15. If a mitigation measure can be applied to a hazard, its probability is reduced by half. Identify the minimal set of hazards that must be mitigated to meet the policy requirement.
