Neil Clark: The Importance of Safety Critical Task Analysis (SCTA)

Описание: https://www.ihf.co.uk/how-to-conduct-...

A safety critical task analysis (SCTA) is a specific form of task analysis that looks at tasks that have potential to be a major accident hazard. It focuses on not just how things may go wrong, but more importantly on how to ensure that these tasks are carried out correctly when called for.

A safety critical task analysis (SCTA) is a specific form of task analysis that looks at tasks that have potential to be a major accident hazard. It focuses on not just how things may go wrong, but more importantly on how to ensure that these tasks are carried out correctly when called for.

Who carries out SCTAs?

SCTAs tend to come in all shapes and sizes. This is in part because of the range of sectors that use them; oil and gas, chemical processing, nuclear and aviation to name but a few. The personnel are not uniform either; they might be done by human factors consultants, HSE managers, process safety engineers, operations managers or someone chosen ad hoc because they seem like the the right person.

The SCTA process and reporting format varies greatly too. IHF have even seen organisations who have several SCTA processes across different sites. Though, more often than not, SCTAs are conducted using generic software such as spreadsheets, word processor documents and the like.

What is the problem with spreadsheet SCTAs?

Whilst it may seem like generic office software achieves the desired results, there are a multitude of potential failures. IHF has previously encountered a company that was working on two versions of the same task analysis, because one was saving to their desktop and the other was saving to the cloud.

On another occasion, a company was asked to produce its safety critical task analyses in advance of a Health and Safety Executive (HSE) inspection. The company was using word processor documents, spreadsheets and diagrams so each SCTA had many files, but the company had not kept the files organised. It took an unnecessarily large amount time to piece them all together before sending to the HSE. These apparent issues with carrying out SCTAs can sometimes encourage organisations to attempt to use less rigorous methods of assessing risk.

How can IHF SaaS TASC™ improve the SCTA process?

IHF SaaS TASC addresses all of these problems and more. Its clear, user-friendly interface is designed to walk users through the SCTA process in its entirety, with powerful tools used to carry out task screening to ensure that time is not wasted carrying out analysis of tasks that carry only minimal risk.

Its task analysis feature helps to ensure that the tasks are broken down into appropriate steps, and allows organisations to gain an understanding not just of how tasks should be carried out, but much more usefully, how they are carried out. This has many benefits including the obvious potential benefit in risk reduction. IHF SaaS TASC can also help to identify effective and safe user knowledge that can be shared organisation wide, reducing costs and increasing productivity.

Most importantly of all however, its Human Error Analysis (HEA) tool is designed in such a way as to allow all potential human errors associated with each subtask to be identified, along with additional factors that may increase — or decrease — the likelihood of the failure. It allows users to identify safeguards that can be put in place, along with mitigations that can be used to improve the outcome should the worst happen. It does all this in a clean, streamlined manner in line with guidance from the HSE, Energy Institute (EI) and other respected organisations with human factors knowledge, helping to improve audit outcomes in the process.
