Rules IV Industrial Services Part 7 Offshore Substations Chapter 3 General Safety Section 3 Means of Escape and Evacuation C Muster Area C.1 General C.1.1 At least one safe route of two from any position on the installation/unit to the muster area shall be available. C.1.2 The muster areas and the access to the evacuation station shall be arranged and protected in order to evacuate the actual number of personnel in an organized and efficient way. Special consideration is to be made to movement of persons on stretchers. C.1.3 The muster area shall be located at lifeboat embarkation point or in a protected area with direct access to lifeboats or other primary way of escape. C.1.4 Muster and embarkation stations should be adequately illuminated by emergency lighting. C.2 Communication and Control C.2.1 The PA, alarm and communication system shall warn and guide personnel as quickly as possible in the event of a hazardous or emergency situation. C.2.2 Minimum following communication facilities are to be provided at primary muster station: • Two hand portable radios • Technical facilities to make PA announcements C.2.3 Facilities to initiate emergency shutdown, if provided, are to be arranged in the vicinity of the muster station. C.2.4 The PA, alarm and emergency communication systems depend on emergency power systems, consisting of emergency generators and UPS. D Electrical Requirements D.1 Emergency lighting and power supply Details see Chapter 5. D.2 Escape route lighting D.2.1 In addition to the emergency lighting the means of escape in accommodation areas, including stairways and exits, should be marked by lighting or photo luminescent strip indicators placed not more than 300 mm above the deck at all points of the escape route, including angles and intersections. The marking should enable personnel to identify the routes of escape and readily identify the escape exits. If electric illumination is used, it should be supplied by the emergency source of power and it should be so arranged that the failure of any single light or cut in a lighting strip will not result in the marking being ineffective. Additionally, escape route signs and fire equipment location markings should be of photo luminescent material or marked by lighting. D.2.2 Such lighting or photo luminescent equipment has been evaluated, tested and applied in accordance with the SOLAS. D.3 Public address, alarm and emergency communication Details see GL Rules for Electrical Equipment (IV-7-5). Edition 2013 Germanischer Lloyd Page 3–4
Rules IV Industrial Services Part 7 Offshore Substations Chapter 3 General Safety Section 3 Means of Escape and Evacuation E Documentation E.1 General All documents submitted for approval and/or review shall include all required details. E.2 List of documents Following drawings are subject for review and approval: • safety plans showing escape and embarkation at each level of the installation/unit with routes and means for personnel protection with following details: ◦ primary and secondary means of escape to be mentioned ◦ width of stairways, doors, corridors and landing areas ◦ muster areas ◦ means of life-saving appliances ◦ location of personal protective equipment • arrangements drawings of stairs and ladders • lighting layouts including marked emergency lighting arrangement • lighting calculation E.3 Evacuation analysis Escape routes shall be evaluated by an evacuation analysis early in the design process. The analysis shall be used to identify and eliminate, as far as practicable, congestion which may develop during abandonment, due to normal movement of personnel and crew along escape routes, including the possibility that a rescue team may need to move along these routes in a direction opposite the movement of personnel. In addition, the analysis shall be used to demonstrate that escape arrangements are sufficiently flexible to provide for the possibility that certain escape routes, assembly stations, embarkation stations or survival craft may not be available as a result of a casualty.
