Incident investigations

In case of emergencies we are available on a 24/7 basis.

Human Factors

In many cases human error is seen as the cause of incidents. Our experts can identify the causes behind human error in order to develop effective safety measures, by applying the human factors science.
Human factors is the application of psychological principles to the engineering and design of products, processes, and systems. The goal of human factors is to reduce human error, increase productivity, and enhance safety and comfort with a specific focus on the interaction between the human and the thing of interest.

Safety Measures

The nature and quality of recommendations for the prevention of future incidents are based on the output of the incident investigation. Part of the planning process involves prioritising and selecting those options that are expected to be most effective and identifying them as the measures requiring priority.

Learning from incidents (LFI) is just one of many activities in managing safety in an organisation. Incident investigation is the most well-known part of the LFI process. Our services go beyond this.
