COMAHI have taken the points from the COMAH report that I found relevant to each element as a direct quote. UNIT 7Element 12: management of change Management of change system ensures that only competent personnel approves any change The Management of Change forms covers the following details: - Location of the work; Description of the work; Hazardous Substances; Risk Assessment completion; Equipment; General comments; and Approvals The Company operates a Management of Change Form system for all minor changes that do not warrant full-scale drafting or design work. Major changes are controlled by assigned personnel under the control of the Terminal Manager. For minor changes, qualified competent staff assess the impact the change would have by either forming a team, carrying out a Risk Assessment, conducting a site audit or a combination of all three. Element 15: inspection and maintenance Designated areas are provided for vehicles held for inspection and documentation production before and after loading and discharging operations. No petrol driven vehicles are permitted within the site boundary. Storage tanks and pipelines are designed to industry standards and subject to planned inspections All equipment is subjected to regular inspection within time periods that are in accordance with known, historically established low corrosion rates for petroleum products. The storage tanks are visually inspected at a frequency of once in six months, 5 yearly internal inspection and subjected to a non-destructive test (NDT) at least every 10 years to monitor the corrosion rate and the expected life of the tank (see Appendix 4). This is consistent with industry practice and the known low corrosion rates. Visual inspection is carried out at every ship discharge (walk on import procedure). Mechanical failure can be caused by fatigue (the effect of vibrations weakening the equipment over sustained period) or inadequate welding. The pump is the only source of vibration but the vibration level is low. If any fatigue were present or inadequate welds the regular condition monitoring inspections are designed to detect this. Corrosion of a storage tank could lead to a release of its contents into the bund. If a source of ignition is present then a fire could develop. The storage tanks are designed to BS 2654 or API 650 and the periodic inspection procedures are consistent with industry best practice. Inadequate design of the tanks could lead to premature failure in a number of ways depending upon the exact nature of the inadequacy. However, such inadequacy should have been identified over the years that the site has been in operation during the regular checks, inspections, audits and maintenance activities. Element 16: Safety Critical Devices Pressure gauges Levels sensors Shut off valves for emergencies Fire alarms Emergency lighting Emergency response system to alert emergency servicesElement 19: Incident Reporting and Investigation All injuries are reported, even if it is minor, and logged in the Accident Book All incidents and near misses are reported, investigated and recorded via the OilCompany Loss Prevention System

UNIT 8The energy institutes high level framework for process safety management states that element 20 is; Audit, assurance, management review & interventionRegular review and audit of compliance with the EI PSM framework is important to ensure that HS&E and process safety performance continue to meet the defined targets.This can be addressed by analysing the given COMAH report. All the systems in place are regularly audited including third party reviews by an accredited body such as HS&E. Site management and operation staff are required to conduct formal inspections that enhance formal audits. External audits are used to verify internal audits while also adding another layer of safety from a different perspective All employees and site users are encouraged to participate in safety committee meetings to make suggestions All meetings have minutes taken and any suggested action is given a deadline and prioritised so that any safety actions can be improved Site budget allows for improvement to safety measures, provision of PPE and maintenance/inspection and to avoid any accidents Any urgent safety modifications approved by the terminal manager has immediate authority to spend additional funds as for any top-tier COMAH site, an incident can be catastrophic

Unit 10Permits to work are important to make sure the qualified people undertake the work and by doing this, major accidents are avoided: The different colours corresponding to different types of work are good for distinguishing at a glance Yellow general work permit low risk work Pink hot work form gas test required before issue Green confined space entry issued as authority to enter and requires a prior gas test Brown excavation used to ensure safety of workers and facilities Isolation isolating machinery or equipment from energy or toxic substances Height work prevent falls and injuriesSubmitting a request for a permit to work takes time and the intention of this is to give the site staff time to prepare the area destined for maintenance. The request necessitates an accompanying method statement and risk assessment to ensure safety to the highest degree.Issuing authority (site staff, project managers etc.) will visit the site that needs maintenance with the contractor to check that all safety precautions and risks are correctly addressed after this permit is agreed.During and after the work is complete, the issuing authority will check that the work has been done to industry standards and once it has been approved, the work will be signed off by both parties.

UNIT 11 Wide range of chemical, physical and toxicological properties determines the environmental impact of spills of ecotoxic substances into a water body. These include: Toxicity to aquatic organisms, which has an acute, direct impact on living species; If insoluble in water and less dense the rate of transfer of gases between the air and the water reduced directly affecting fauna (lack of oxygen) and photosynthesising flora (lack of carbon dioxide and oxygen); If soluble and dispersing with an adverse effect such as a high BOD or pH change; If insoluble in water and with a higher density than water so that it can interact with benthic species and persist; and Bioaccumulation potential causing chronic effects. It stores a variety of hazardous substances however the risk to local populations is small and can arise as a result of fire or spill of a significant quantity of certain substances. Analysis shows that the maximum distance which dangerous levels of thermal radiation or a dangerous toxic load of hazardous combustion could be experienced, following an on-site incident, is less than 100m. All the major accident hazards were identified and the environmental effects on the air, aquatic environment and land were assessed.
