2          Formula for calculating the total mass of combustible materials

 

 

2.1       Inaccommodationspaces,servicespacesandcontrolstationsofalltypesofships,thetotalmassof combustible materials of each enclosed space should be calculated based on the following formula:

 

 

TCMPA = MCMBST/A

 

 

where:

 

 

TCMPA is the total mass of combustible materials per unit area of the space (kg/m2)

 

 

M CMBS T   is the total mass of combustible materials of the space (kg); and

 

A is thefloor area of the space (m2).

 

 

2.2       Thefollowingcombustiblematerialsshouldbeincludedinthecalculationrequiredbyparagraph2.1:
