The structure of the assessment addresses the following nine critical topics:
- Task analysis
- Operational procedures
- Competence management and training
- Alertness and fatigue
- Shift handover
- Control room ergonomics
- Workstation environmental condition
- Human machine interface
- Management of alarms
These criteria have been selected from a list of ‘Operationalised human factors’ areas of concern published by the UK Health and Safety Executive (UK HSE) for high hazard sites. Using these parameters assists in benchmarking an organisation against current regulatory expectations and established best practice. It also helps to target recommendations to be more effective in improving occupational and process safety as well as operational efficiency.
As illustrated in the example below, each topic area, for each site was scored against the word model on a scale of 0 – 5 where 0 indicates no awareness / implementation of the topic, and 5 indicates best in class in all elements of the word model
This resulted in a benchmark not only against established good practice but also provided an internal comparison against company standards and other stations within the fleet. A number of examples of ‘world class’ performance were identified in the study, including; individual verbal handover protocols, the use of practical ‘table-top’ exercises and the roll-out of electronic procedures to hand-held devices. These, and other examples of best practice, are now being implemented across the fleet to transfer benefits across the whole of SSE’s energy generation operations.
The assessment for each station was documented in a report, which highlighted current good practice and recommendations for improvement. The outcome of each assessment was presented to the local management team at the conclusion of each station visit.
