4.1.1 For the general requirements for means of escape, see Part D - Escape, Chapter III - Life-saving appliances and arrangements and LSA Code - International Life-Saving Appliance Code – Resolution MSC.48(66) . For units with drilling facilities, see also the requirements of 9.4 Means of escape and Chapter 10 - Life-Saving Appliances and Equipment

4.1.2 Escape ways on units with production and process plant are to be adequately protected against potential fire loadings emanating from the topside plant and production facilities. The following objectives are to be considered when evaluating the unit’s requirements for escape, evacuation and rescue, as also required to be detailed in the Escape, Evacuation and Rescue Assessment (EERA), referred to in Pt 7, Ch 3, 1.2 Submission of documentation 1.2.4:
  • To maintain the safety of all personnel when they move to another location to avoid the effects of a hazardous event.
  • To provide a refuge on the unit for as long as required to enable a controlled evacuation of the unit.
  • To facilitate recovery of injured personnel.
  • To ensure safe abandonment of the installation or unit.

4.1.3 Where sufficient physical barriers do not exist, escape ways are to be protected by way of active (deluge cooling) or passive (fire screen) type systems.

4.1.4 Escape route widths are to be considered with relation to the number of personnel and individual occupancy of all topsides process and turret areas. Escape routes are to be provided to enable all personnel to evacuate an area safely, when they are directly affected by an incident.
