Escape, Evacuation & Rescue Analysis (EERA) Study Report For Adani Mundra Port


The Adani Group has expressed its intention to expand its existing port facility at Adani Mundra Port Pvt Ltd.  Adani is currently in the process of developing a facility for handling and storing LPG, propane, and butane at their port located in Mundra. In the event of a decline in LPG business, it is anticipated that propylene and propane will be stored and managed at the terminal. This document provides the results of Escape, Evacuation and Rescue Analysis carried out for the project, in accordance with the standard guidelines.


The objective of the Escape, Evacuation and Rescue Analysis (EERA) is to systematically address the effects of accidental events on the adequacy and the availability of Escape, Evacuation and Rescue (EER) systems and to perform their intended functions. The study will cover the following;

  • Escape Routes Analysis – Each area on the facility to be assessed in terms of provision of escape provisions in accordance with OGP guidelines.
  • Evacuation Time Analysis – The objective of the evacuation time analysis is to assess if the assembly area and evacuation facilities can endure fire events for the period required for the personnel in the plant to evacuate;
  • Evacuation Provision Analysis – To check for adequate provision of the evacuation facility, such that all personnel could safely evacuate the facility, when required; and
  • Rescue Provision Analysis – To assess the provision of rescue facility for suitability and adequacy.
  • Provide suitable recommendations for the impaired escape routes.

EERA Methodology

The methodology consists of:

  1. Identification of credible MAH scenarios which could require evacuation of the place to avoid or minimize a major accident
  2. Modelling of event consequences, in terms of impairment of means of evacuation and escape, and performance of life-saving equipment in the prevailing conditions.
  3. Identify the safe areas on the Facility, both Assembly Points and the Place of Safety (Safe Site Location),
  4. Define escape routes to relevant assembly point for typical population distributions.
  5. Analyze the escape route timings to establish where there are limitations on the ability of personnel to reach a safe location within 10mins.
  6. Generate a matrix of escape routes that define the routes from each populated area.
  7. Provide comments on improvement of existing EER facilities on the installation based on EER assessment


In any facility, prevention of Fire, Explosion and Emergency Response require the duty holders/facility personnel to ensure adequate arrangements for escape, evacuation, rescue and recovery of persons involved in an incident.

The Purpose of EER goals are:

  • To demonstrate all reasonably practicable measures have been taken to ensure the safe and effective evacuation, escape and rescue of personnel from the installation,
  • To demonstrate the adequacy of the evacuation, escape and rescue provisions in response to accident conditions,
  • To provide guidance for management of emergencies.

The Purpose of the EER is not to produce an emergency response plan; this shall be completed before the operations phase.

Review and Assessment

The estimated time for escape and evacuation is determined based on length of escape route.

In the event of a fire alert at site, approximate time for personnel to reach Assembly Point has been calculated as per HSE UK Guideline and the following speeds are reached.

Time to reach Assembly point

  • Pedestrian speed, on flat = 1.4 m/s
  • Pedestrian speed, up and down stairs = 1.0 m/s
  • Pedestrian speed, down ladders = 0.3 m/s

For estimating the calculation of escape time to the assembly point from the plant facilities, it has been assumed that:

  • Personnel will walk to the Assembly Point. Therefore, escape times represent a “worst case”.
  • Escape from a Tank, Mounted Bullet and Heating Train area includes time taken to descend ladders from the top.

Assessment and Exposure of Escape Routes to Fire Events

The various escape routes from the different areas of LPG Terminal Mundra facility have been identified and studied with respect to the assembly point.  Assessment of exposure of escape routes is based on thermal distances obtained from consequence modelling in DNV GL PHAST for the credible scenario of 25 mm leak.


The EER facilities have been assessed for their adequacy and effectiveness in achieving the specified goals for escape, evacuation and rescue. The credible scenarios were derived from QRA and the escape time required for the personnel have been estimated using designated safe escape routes, to enable plant personnel to reach the designated assembly points.
