^c:o SAFETY OF LIFE AT SEA 



Regulation 34 



General 





(a) The purpose of this Part is to require the fullest practicable degree 

 of protection from fire by regulation of the details of arrangement and 

 construction. The three basic principles underlying these regulations are: 



(i) separation of the accommodation spaces from the remainder of the 

 ship by thermal and structural boundaries; 



(ii) containment, extinction, or detection of any fire in the space of 

 origin; 



(iii) protection of means of escape. 



{b) The hull, superstructure and deck houses shall be divided into main 

 vertical zones by " A " Class bulkheads (as described in paragraph (c) of 

 Regulation 35 of this Chapter) and further divided by similar bulkheads 

 forming the boundaries protecting spaces which provide vertical access and 

 the boundaries separating the accommodation spaces from the machinery, 

 cargo and service spaces and others. In addition, and supplementary to the 

 patrol systems, alarm systems and fire extinguishing apparatus required by 

 Part E of this Chapter, either of the following methods of protection, or a 

 combination of these methods to the satisfaction of the Administration, shall 

 be adopted in accommodation and service spaces with a view to preventing 

 the spread of ingipient fires from the spaces of their origin : — 



Method I. — The construction of internal divisional bulkheading of " B " 

 Class divisions (as defined in paragraph (d) of Regulation 35 of this 

 Chapter) generally without the installation of a detection or sprinkler 

 system in the accommodation and service spaces; or 



Method II. — The fitting of an automatic sprinkler and fire alarm system 

 for the detection and extinction of fire in all spaces in which a fire 

 might be expected to originate, generally with no restriction on the type 

 of internal divisional bulkheading in spaces so protected; or 



Method III. — A system of subdivision within each main vertical zone 

 using " A " and " B " Class divisions distributed according to the 

 importance, size and nature of the various compartments, with an 

 automatic fire detection system in all spaces in which a fire might 

 be expected to originate, and with restricted use of combustible and 

 highly inflammable materials and furnishings; but generally without 

 the installation of a sprinkler system. 



Where appropriate, the headings or sub-headings of the Regulations of this 

 Part of this Chapter indicate under which Method or Methods the Regulation 

 is a requirement.
