At a pharmaceutical intermediate plant, a 4 m3 glass-lined reactor is used for a highly exothermic Grignard reaction. The cooling system relies on a single centrifugal pump drawing from a cooling water header. The HAZOP identified 'loss of agitation' and 'loss of cooling' as causes of runaway. The current design has a low-flow trip on the coolant pump that shuts the feed valves, but no independent temperature-based trip on the reactor itself. A proposed modification adds a second coolant pump with automatic start on low flow. The process safety engineer argues that this is sufficient because the pumps are now redundant. What is the critical missing element for adequate hazard control of the reaction?
The site emergency plan at the upper-tier COMAH chlorine facility requires a full-scale exercise involving the local authority and emergency services every three years. The last full exercise was 28 months ago. A tabletop exercise was conducted last year. A new shift team has joined since the last full exercise. What is the minimum acceptable position?
A LOPA team is assessing a high-pressure acid gas absorber. The initiating event is loss of lean amine circulation (frequency 3 10^{-2} per year). Without safeguards the consequence frequency exceeds the company tolerability limit by a factor of 300. The team identifies the following potential IPLs: BPCS flow control (PFD 0.1), operator response to low flow alarm (PFD 0.1), and a proposed SIF (target PFD 0.01). The BPCS and the proposed SIF both use the same flow transmitter. Which of the following is the correct LOPA treatment?
A HAZOP on a proposed modification to add a recycle line around the ethylene oxide reactor at Acme Petro has generated the deviation 'NO FLOW' in the recycle line. The team notes that continued fresh feed under this condition could cause a rapid temperature rise. One team member suggests that because the basic control system will alarm on high reactor temperature, no additional safeguards are required for this node. Which of the following is the most appropriate HAZOP team response?
The safety report for the upper-tier COMAH site at Severnside Chlorine must demonstrate that risks from chlorine release have been reduced ALARP. The report shows that a new 50-tonne storage tank was installed without a full options analysis because the incremental cost of a double-walled tank with vapour suppression was 2.7 m. The site claims the risk is already below 10^-5/yr. Which test of ALARP has not been properly applied?
