Support to safety case
The UK’s Offshore Installations (safety case) Regulations 2005 require operators and owners to submit safety cases for their installations. Human factors features strongly amongst the principles against which the quality and completeness of the safety case submission is assessed.
Principle 8 states that “the major accident risk evaluation should take account of human factors.” The HSE advises that the risk assessment should consider people as both a key element in safe operation and as a potential cause of major accidents and their escalation. In other words, the role of human and organisational factors in defending against major accidents as well as the potential contribution of human failures to this risk should be determined and assessed. A safety critical task review approach is recommended.
Human Engineering has developed a safety critical task review methodology that meets the demands for a deterministic approach to risk assessment. This is based upon established good practice in human reliability analysis and supports the assessment of the feasibility of tasks and the usability of interfaces to plant and equipment. It also examines a wide range of performance shaping factors such as management systems, competence, procedures, hazards, etc that can affect the quality of human performance. The method includes screening steps to allow the depth of analysis to be tailored to the risk of failure and its consequences.
