Notes: to be applied to tables 26.1 and 26.2
a Where adjacent spaces are in the same numerical category and superscript a appears, a bulkhead or deck between such spaces need not be fitted if deemed unnecessary by the Administration. For example, in category (12) a bulkhead need not be required between a galley and its annexed pantries provided the pantry bulkhead and decks maintain the integrity of the galley boundaries. A bulkhead is, however, required between a galley and a machinery space even though both spaces are in category (12).
b The ship's side, to the waterline in the lightest seagoing condition, superstructure and deckhouse sides situated below and adjacent to the liferafts and evacuation slides may be reduced to A-30.
c Where public toilets are installed completely within the stairway enclosure, the public toilet bulkhead within the stairway enclosure can be of "B" class integrity."

Regulation II-2/28 - Means of escape
37 Delete "accommodated or" from the last sentence of paragraph 1.1.
38 Replace paragraph 1.4 by the following:
"1.4 A corridor, lobby, or part of a corridor from which there is only one route of escape shall be prohibited."
39 Replace paragraph 1.5 by the following:
".5 At least one of the means of escape required by paragraphs 1.1 and 1.2 shall consist of a readily accessible enclosed stairway, which shall provide continuous fire shelter from the level of its origin to the appropriate lifeboat and liferaft embarkation decks, or to the uppermost weather deck if the embarkation deck does not extend to the main vertical zone being considered. In the latter case, direct access to the embarkation deck by way of external open stairways and passageways shall be provided and shall have emergency lighting in accordance with Regulation III/11.5 and slip-free surfaces under foot. Boundaries facing external open stairways and passageways forming part of an escape route and boundaries in such a position that their failure during a fire would impede escape to the embarkation deck shall have fire integrity, including insulation values, in accordance with the tables in Regulation II-2/26. The widths, number and continuity of escapes shall be as follows:
.5.1 Stairways shall not be less than 900 mm in clear width. Stairways shall be fitted with handrails on each side. The minimum clear width of stairways shall be increased by 10 mm for every one person provided for in excess of 90 persons. The maximum clear width between handrails where stairways are wider than 900 mm shall be 1,800 mm. The total number of persons to be evacuated by such stairways shall be assumed to be two thirds of the crew and the total number of passengers in the areas served by such stairways. The width of the stairways shall conform to standards not inferior to those adopted by the Organization.
.5.2 All stairways sized for more than 90 persons shall be aligned fore and aft.
.5.3 Doorways and corridors and intermediate landings included in means of escape shall be sized in the same manner as stairways.
.5.4 Stairways shall not exceed 3.5 m in vertical rise without the provision of a landing and shall not have an angle of inclination greater than 45°.
.5.5 Landings at each deck level shall be not less than 2 m2 in area and shall increase by 1 m2 for every 10 persons provided for in excess of 20 persons but need not exceed 16 m2, except for those landings servicing public spaces having direct access onto the stairway enclosure."
40 Add new paragraphs 1.9 and 1.10 as follows:
".9 Where the Administration has granted dispensation under the provisions of paragraph 1.1, the sole means of escape shall provide safe escape. However, stairways shall not be less than 800 mm in clear width with handrails on both sides.
.10 In addition to the emergency lighting required by Regulations II-1/42 and III/11.5, the means of escape, including stairways and exits, shall be marked by lighting or photoluminescent strip indicators placed not more than 0.3 m above the deck at all points of the escape route including angles and intersections. The marking must enable passengers to identify all the routes of escape and readily identify the escape exits. If electric illumination is used, it shall be supplied by the emergency source of power and it shall 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, all escape route signs and fire equipment location markings shall be of photoluminescent material or marked by lighting. The Administration shall ensure that such lighting or photoluminescent equipment have been evaluated, tested and applied in accordance with the guidelines developed by the Organization."
41 Add a new paragraph 3.3 as follows:
"3.3 Two means of escape shall be provided from a machinery control room located within a machinery space, at least one of which will provide continuous fire shelter to a safe position outside the machinery space."
Regulation II-2/29 - Protection of stairways and lifts in accommodation and service spaces
42 Replace paragraph 2 by the following:
"2 Stairway enclosures shall have direct access to the corridors and be of a sufficient area to prevent congestion, having in view the number of persons likely to use them in an emergency. Within the perimeter of such stairway enclosures, only public toilets, lockers of non-combustible material providing storage for safety equipment and open information counters are permitted. Only public spaces, corridors, public toilets, special category spaces, other escape stairways required by 28.1.5 and external areas are permitted to have direct access to these stairway enclosures."
Regulation II-2/30 - Openings in "A" class division
43 Replace paragraph 4 by the following:
"4 Fire doors in main vertical zone bulkheads and stairway enclosures shall satisfy the following requirements:
.1 The doors shall be self-closing and be capable of closing with an angle of inclination of up to 3.5° opposing closure, and shall have an approximately uniform rate of closure of no more than 40 s and no less than 10 s with the ship in the upright position.
.2 Remote-controlled sliding or power-operated doors shall be equipped with an alarm that sounds at least 5 s but no more than 10 s before the door begins to move and continue sounding until the door is completely closed. Doors designed to reopen upon contacting an object in its path shall reopen sufficiently to allow a clear passage of at least 0.75 m, but no more than 1 m.
.3 All doors shall be capable of remote and automatic release from a continuously manned central control station, either simultaneously or in groups, and also individually from a position at both sides of the door. Indication must be provided at the fire control panel in the continuously manned central control station whether each of the remote-controlled doors are closed. The release mechanism shall be so designed that the door will automatically close in the event of disruption of the control system or central power supply. Release switches shall have an on-off function to prevent automatic resetting of the system. Hold-back hooks not subject to central control station release are prohibited.
.4 Local power accumulators for power-operated doors shall be provided in the immediate vicinity of the doors to enable the doors to be operated at least ten times (fully opened and closed) using the local controls.
.5 Double-leaf doors equipped with a latch necessary to their fire integrity shall have a latch that is automatically activated by the operation of the doors when released by the system.
.6 Doors giving direct access to special category spaces which are power-operated and automatically closed need not be equipped with alarms and remote-release mechanisms required in .2 and .3."
44 In paragraph 5, add the following words at the beginning:
"In ships carrying not more than 36 passengers,".
45 In paragraph 6, add the following words at the end of the first sentence:
"provided that there is no requirement for such boundaries to have "A" class integrity in Regulation 33.3".
46 Insert a new paragraph 7 as follows:
"7 All "A" class doors located in stairways, public spaces and main vertical zone bulkheads in escape routes shall be equipped with a self-closing hose port of material, construction and fire resistance which is equivalent to the door into which it is fitted, and shall be a 150 mm square clear opening with the door closed and shall be inset into the lower edge of the door, opposite the door hinges, or in the case of sliding doors, nearest the opening."
Regulation II-2/31 - Openings in "B" class division
