Escape, Evacuation and Rescue Analysis

Escape, Evacuation and Rescue Analysis ensures that the design of a facility is such that the risk to personnel is kept to within the ALARP region.

Escape, Evacuation and Rescue Analysis


In the event of a major incident, the design of a facility must be such that any ensuing risk to personnel can be assessed to a level considered to be As Low As Reasonably Practicable (ALARP). This can often be achieved through the provision of suitable means of Escape, Evacuation and Rescue (EER) in conjunction with the implementation of suitable emergency response procedures and training.




What inputs are required by FSES to conduct the EERA Study?

As a minimum the following information would be required to conduct the workshop:

Existing PHA / HAZOP report


Facility Emergency Response Procedures

Facility Loss Prevention Philosophy

Consequence Analysis report and models

Based on the project requirements, extra information may be required. This will be highlighted within the Terms of Reference (ToR).

What is the expected output of the EERA Study?

On award of the study FSES will issue a project ToR. This will highlight the assumptions that will be made in the study. The ToR will also include a detailed methodology and data sources that will be utilised. Any further information required from the client will be identified.
Upon acceptance of the ToR, FSES will prepare an EERA report describing the facility, the scope of work, a detailed methodology, the identified hazardous scenarios, muster points, refuge areas, means, routes and timing of EER, emergency equipment, the results of the analysis, and any recommendations based on deficiencies identified with the EER.




FSES are a globally renowned providers of engineering and safety services. FSES have conducted EERA’s for several offshore platforms. FSES also have the capability to conduct them for onshore facilities, accommodation facilities and construction vessels amongst others.
