2.2.1.   Main vertical zones and horizontal zones

	2.2.1.1.1	In ships carrying more than 36 passengers, the hull, superstructure and deckhouses shall be subdivided into main vertical zones by A-60 class divisions. Steps and recesses shall be kept to a minimum but, where they are necessary, they shall also be A-60 class divisions. Where a category (5), (9) or (10) space defined in paragraph 2.2.3.2.2, is on one side or where fuel oil tanks are on both sides of the division, the standard may be reduced to A-0.
---	---	---
	2.2.1.1.2	For ships carrying not more than 36 passengers, the hull, superstructure and deckhouses in way of accommodation and service spaces shall be subdivided into main vertical zones by ‘A’ class divisions. These divisions shall have insulation values in accordance with the tables in paragraph 2.2.4.
---	---	---
	2.2.1.2.	As far as practicable, the bulkheads forming the boundaries of the main vertical zones above the bulkhead deck shall be in line with watertight subdivision bulkheads situated immediately below the bulkhead deck. The length and width of main vertical zones may be extended to a maximum of 48 metres in order to bring the ends of main vertical zones to coincide with subdivision watertight bulkheads or in order to accommodate a large public space extending for the whole length of the main vertical zone provided that the total area of the main vertical zone is not greater than 1 600 m2 on any deck. The length or width of a main vertical zone is the maximum distance between the furthermost points of the bulkheads bounding it.
---	---	---
	2.2.1.3.	Such bulkheads shall extend from deck to deck and to the shell or other boundaries.
---	---	---
	2.2.1.4.	Where a main vertical zone is subdivided by horizontal ‘A’ class divisions into horizontal zones for the purpose of providing an appropriate barrier between a zone with sprinklers and a zone without sprinklers, the divisions shall extend between adjacent main vertical zone bulkheads and to the shell or exterior boundaries of the ship and shall be insulated in accordance with the fire insulation and integrity values given in table 9.4.
---	---	---
	2.2.1.5.1	On ships designed for special purposes, such as automobile or railroad car ferries where the provision of main vertical zone bulkheads would defeat the purpose for which the ship is intended, equivalent protection shall be obtained by dividing space in horizontal zones.
---	---	---
	2.2.1.5.2	However, in a ship with special category spaces, any such space shall comply with the applicable provisions of Regulation II-2/G/20 and in so far as such compliance would be inconsistent with compliance with other requirements of this part, the requirements of Regulation II-2/G/20 shall prevail.

2.2.2.   Bulkheads within a main vertical zone

	2.2.2.1.	For ships carrying more than 36 passengers all bulkheads which are not required to be ‘A’ class divisions shall be at least ‘B’ class or ‘C’ class divisions as prescribed in the tables in paragraph 2.2.3. All such divisions may be faced with combustible materials in accordance with the provisions of Regulation II-2/B/5, paragraph 3.
---	---	---
	2.2.2.2.	For ships carrying not more than 36 passengers all bulkheads within accommodation and service spaces which are not required to be ‘A’ class divisions shall be at least ‘B’ class or ‘C’ class divisions as prescribed in the tables in paragraph 2.2.4. All such divisions may be faced with combustible materials in accordance with the provisions of Regulation II-2/B/5, paragraph 3. In addition, in ships carrying not more than 36 passengers all corridor bulkheads, where not required to be ‘A’ class, shall be ‘B’ class divisions which shall extend from deck to deck except: .1 when continuous ‘B’ class ceilings or linings are fitted on both sides of the bulkhead, the portion of the bulkhead behind the continuous ceiling or lining shall be of material which, in thickness and composition, is acceptable in the construction of ‘B’ class divisions, but which shall be required to meet ‘B’ class integrity standards only in so far as is reasonable and practicable; .2 in the case of a ship protected by an automatic sprinkler system complying with the provisions of Regulation II-2/C/10, subparagraph 6.1.100, the corridor bulkheads of ‘B’ class materials may terminate at a ceiling in the corridor provided such ceiling is of material which, in thickness and composition, is acceptable in the construction of ‘B’ class divisions. Notwithstanding the requirements of paragraph 2.2.4, such bulkheads and ceilings shall be required to meet ‘B’ class integrity standards only in so far as is reasonable and practicable. All doors and frames in such bulkheads shall be of non-combustible materials and shall be so constructed and erected as to provide substantial fire resistance.
---	---	---
	2.2.2.3.	All bulkheads required to be ‘B’ class division, except corridor bulkheads prescribed in paragraph 2.2.2.2, shall extend from deck to deck and to the shell or other boundaries unless the continuous ‘B’ class ceilings or linings fitted on both sides of the bulkheads are at least of the same fire resistance as the bulkhead, in which case the bulkhead may terminate at the continuous ceiling or lining.
