Rules IV Industrial Services Part 7 Offshore Substations Chapter 3 General Safety Section 6 Fire Safety - General D.4.3 "B" class divisions shall be constructed of approved non-combustible materials, and all materials entering into the construction and erection of "B" class divisions shall be non-combustible, with the exception that combustible veneers may be permitted, provided they meet other requirements of this Section. D.5 "C" class divisions "C class divisions" are divisions constructed of approved non-combustible materials. They need meet neither requirements relative to the passage of smoke and flame nor limitations relative to the temperature rise. Combustible veneers are permitted, provided they meet other requirements of this Section. D.6 Low flame spread Low flame spread means that the surface thus described will adequately restrict the spread of flame, this being determined to the satisfaction of GL by an established test procedure. D.7 Steel or other equivalent material Where the words "steel or other equivalent material" are used, "equivalent material" means any noncombustible material which, by itself or due to insulation provided, has structural and integrity properties equivalent to steel at the end of the applicable exposure to the standard fire test (e.g. aluminium alloy with appropriate insulation). E Submission of Documents The following documents shall be submitted for approval: • General arrangement plans, indicating the intended purpose of the installation or unit, the purpose of each area or room and the arrangements of machinery and equipment. • Plans and documents detailing the arrangements of structural fire protection measures. • Plans and documents detailing fire extinguishing as well as fire detection and alarm systems. • Plans and documents detailing the relevant control system for the remote closure of fire doors and relevant valves. • Ventilation system plans showing the ducts and fire dampers and the positions of the controls for stopping the system. • Fire control plans.

Fire divisions shall ensure that a dimensioning fire and explosion does not escalate into surrounding areas. Passive fire protection shall prevent or mitigate serious consequences from fire also to protect personnel (heat and smoke) and make escape or evacuation possible. A.2 Definitions of spaces A.2.1 Control stations Spaces which contain the following equipment are considered as Control Stations: • operational control systems • radio and telephone systems including emergency communication • fire detection and fire control systems • emergency source of power • fire extinguishing systems serving various locations A.2.2 Corridors Corridors are spaces which serve the purpose of connecting other areas in order to provide carriage of personnel. A.2.3 Accommodation spaces Accommodation spaces are those used as public spaces, corridors, lavatories, cabins, offices, hospitals, cinemas, recreational rooms, pantries containing no cooking appliances and similar spaces. Public spaces are those portions of the accommodation which are used for halls, dining rooms, lounges and similar permanently enclosed spaces. A.2.4 Stairways Stairways are internal stairways, lifts and escalators (other than those wholly contained within the machinery spaces) and enclosures thereto. In this connection a stairway, which is enclosed only at one level, shall be regarded as part of the space from which it is not separated by a fire door. A.2.5 Service spaces (low risk) Service spaces (low risk) are lockers, laundries, store rooms and working spaces, in which no flammable materials are stored. Edition 2013 Germanischer Lloyd Page 7–1
