Escape Evacuation Rescue Analysis (EERA)

In the event of a significant incident, the design of a facility must be such any ensuing risk to personnel can often assessed to a level considered to be as Low as Reasonably Practicable (ALARP). EERA can be achieved through the availability of suitable Escape, Evacuation and Rescue (EER) in addition with the implementation of suitable emergency response procedures and training.

All facilities should have an Emergency, Escape, and Rescue (EER) plan whose object is to form sure the safety of personnel during the course of an emergency. The subsiquent guidance is for offshore facilities, which are generally very congested, but it’s useful for developing a perfect plan onshore.

  • Provide a way for personnel to go away their area of work where the incident is happening.
  • Provide a secure area or temporary refuge where personnel can gather until the incident is brought in restraint. The safe area should be ptotected from smoke and gas ingress (flammable and toxic), oxygen deficiency, CO2 accumulation and excessive heat.
  • Provide secure communication in order that personnel can coordinate their activities with the emergency response services.
  • Provide full evacuation of the facility if needed.

Significance of EERA study

  • Identify escape, evacuation and rescue (EER) facilities provided to enable personnel to flee from the immediate effects of accident events, and, if necessary, evacuate the installation and reach an ultimate place of safety.
  • From the results of FERA consequence modelling identification of accident events that might necessitate the utilization of the EER facilities.
  • Assess whether the defined EER goals and objectives are met, and if not, actions required to satisfy the goals.

It is recommended that EER issues to be addressed during a simultaneous operations (SIMOPS).

Why EERA

  • To Determine the availability of escape routes following a significant accident event, and therefore the potential for impairment of EER facilities, once they’re required.
  • To evaluate the endurance time required by the EER facilities supported estimating time of muster and evacuation.

Benefits of EERA

In the event of emergency situations, efficient escape, evacuation and rescue are becoming to be vital to avoid injuries and fatalities. Our expertise and diary spans multiple sectors including the oil & gas industry, maritime-, offshore wind- and transportation industry (e.g. tunnels) also  as buildings. The general objective of such analyses is to measure whether

  • Escape to safe areas are going to be possible before being exposed to accidental loads (e.g. heat, smoke, toxic atmospheres).
  • Evacuation from the analysed object are going to be possible during a controlled manner before critical exposure of safe areas and/or evacuation means occurs
  • Rescue and treatment of persons not having the ability to evacuate are going to be possible
  • Rescue treatment facilities are going to be available for injured persons following evacuation.

Evaluation of "bottlenecks" in escape routes, which may increase escape times, could also be an important a neighborhood of such analyses.

Codes

  • MODU – Code for the development and equipment of Mobile Offshore Drilling Units
  • IMO – International Marine Organisation

Report Output

It is essential to think about QRA results for assessing EER arrangements in hydro carbon processing facility where the amount of major accident events existence is high and develop scenarios for preparing Emergency response plans.
