Requirements

Decks and Bulkheads — Accommodation Spaces, Service Spaces and Control Stations

      • (ii) consist of “A-60” class divisions, if the machinery space is of category A and is not fitted with a fixed fire-extinguishing system; and

    • (b) a deck or bulkhead that separates a control station from an accommodation space or service space must consist of “B-15” class divisions.

    • (a) “A-15” class divisions; or

    • (b) “B-15” class divisions, in the case of a galley in which any ovens, hot water appliances or other appliances are heated only by electricity.

  •  (1) On a vessel whose hull is constructed of combustible materials,

    • (a) a deck or bulkhead that separates a machinery space from an accommodation space, service space or control station must consist of “F” class divisions or of “B-15” class divisions;

    • (b) a deck or bulkhead that separates a control station from an accommodation space or service space must consist of “F” class divisions; and

    • (c) the machinery space boundaries must, to the extent feasible, prevent the passage of smoke.

  • (2) On a vessel whose hull is constructed of combustible materials, if a deck or boundary bulkhead contains an emergency source of power or if a deck or bulkhead separates a galley, paint-room, lamp-room or storeroom that contains highly flammable materials from an accommodation space, service space or control station, the deck or bulkhead must consist of “F” class divisions or of “B-15” class divisions.

Bulkheads of Corridors

  •  (1) On a vessel whose hull is constructed of non-combustible materials, the bulkhead of a corridor that serves an accommodation space, service space or control station must consist of “B-0” class divisions.

  • (2) On a vessel whose hull is constructed of combustible materials, the bulkhead of a corridor that serves an accommodation space, service space or control station must consist of “F” class divisions or of “B-0” class divisions.

  • (3) The bulkhead of a corridor that serves an accommodation space, service space or central control station must extend from deck to deck unless a continuous ceiling of the same class division as the bulkhead is fitted on both sides of the bulkhead, in which case the bulkhead may terminate at the continuous ceiling.

Substitution of Class Divisions

 For the purposes of sections 205 to 207,

  • (a) “A” class divisions may be used instead of “B-15” class divisions or “F” class divisions;

  • (b) “A-15”, “A-30” or “A-60” class divisions may be used instead of “A-0” class divisions;

  • (c) “A-30” or “A-60” class divisions may be used instead of “A-15” class divisions; and

  • (d) “B-15” class divisions may be used instead of “B-0” class divisions.

Penetrations of Decks and Bulkheads

 The fire integrity of the divisions required by sections 205 to 207 must not be impaired by the passage of electrical cables, pipes, trunks, ducts or other transit devices through the divisions.

Interior Stairways

  •  (1) An interior stairway that serves an accommodation space, service space or control station must be constructed of steel or other equivalent material.

  • (2) On a vessel whose hull is constructed of non-combustible materials, an interior stairway that connects more than two decks must be within an enclosure constructed of “B-15” class divisions.

  • (3) On a vessel whose hull is constructed of combustible materials, an interior stairway that connects more than two decks must be within an enclosure constructed of “F” class divisions.

Lift Trunks

 A lift trunk that passes through an accommodation space or service space must be constructed of steel or other equivalent material and must be provided with a means of closing that permits control of drafts and smoke.

Doors and Other Closures of Openings

  •  (1) The following doors and other closures of openings must have fire-resistant properties equivalent to those of the class divisions of the structures in which they are fitted:

    • (a) doors in an engine or boiler casing;

    • (b) doors and other closures of openings in a deck or bulkhead referred to in sections 205 to 207; and

    • (c) doors in an enclosure referred to in subsection 210(2) or (3).

  • (2) The doors to machinery spaces of category A must be self-closing and reasonably gastight.

  • (3) A door required by subsection (1) that is in an “A” class division must be reasonably gastight.

  • (4) Every door in an “A” class division must overlap the door frame, and allow for a gap, between the edges of the door and the top, bottom and sides of the door frame, that is the minimum needed to open and close the door.

  • (5) A grille or louvre must not be fitted in a door required by subsection (1) that is in an “A” class division.

  • (6) A hose port that is fitted in a door required by subsection (1) that is in an “A” class division must

    • (a) be self-closing;

    • (b) be constructed of material that has fire-resistance that is at least equivalent to the door in which it is fitted;

    • (c) have a clear opening that has a width and length of 150 mm when the door is closed; and

    • (d) be inset into the lower edge of the door, either on the side opposite the door hinges or, in the case of a sliding door, on the side nearest the opening.

  • (7) Every door required by subsection (1) that is in an “A” or “B” class division must be fitted with a thin metal identification plate that

    • (a) has clearly stamped on it the door manufacturer’s name, the “A” or “B” class rating, the type approval certificate number and the number of the drawing to which the door has been manufactured; and

    • (b) is screwed or riveted to either of the vertical edges of the door panel.

Skylights and Other Windows

  •  (1) If a skylight in a machinery space can be opened, the skylight must be capable of being closed from outside the space.

  • (2) Glass, acrylic or any other similar material must not be fitted in machinery space boundaries. However, wire-reinforced glass may be fitted in skylights and fire-rated glass may be fitted in windows in control rooms within machinery spaces.

  • (3) A skylight that is in a machinery space and contains wire-reinforced glass must be fitted with permanently attached external shutters of steel or other equivalent material.

Air Spaces

 Air spaces enclosed behind ceilings, panelling or linings in accommodation spaces, service spaces or control stations must be divided by close-fitting draft stops spaced not more than 7 m apart.

Insulating Materials

  •  (1) Insulating materials must be non-combustible, except in a cargo space, mail room, baggage room, or refrigerated compartment of a service space. However, vapour barriers and adhesives used with insulating materials, as well as the insulating materials used for pipe fittings for cold service systems, need not be of non-combustible materials if the non-combustible materials are the minimum quantity feasible and their exposed surfaces have low flame spread characteristics.

  • (2) The exposed surface of insulating materials fitted on the internal boundaries of machinery spaces of category A must be impervious to oil and oil vapours.

 If organic foam is used in a cargo space or a refrigerated compartment of a service space,

  • (a) the exposed surfaces of the foam must be

    • (i) sealed with an intumescent coating that meets the flame spread, smoke and toxicity requirements set out in Annex 1 to the FTP Code, and

    • (ii) covered with a steel-sheet protective facing;

  • (b) in the case of organic foam used in a cargo space or a refrigerated compartment of a service space on a vessel of steel construction, the boundaries to the space must be of steel construction; and

  • (c) in the case of organic foam used in a refrigerated compartment of a service space on a vessel of aluminum construction, the boundaries to the space must be of steel or aluminum construction.
