We can NOT think A-0 dividion has nothing to do with fire-retarding.
It includes two facts:
1: required structural strength;
2: fire-retarding performance; (refer to FTP code for more details)
So, when treating with these beams/stiffeners penetrating the margin bulkheads, patches is a must. This is most important!
Another interesting item is the windows on bulkheads of ECR.
Ruls&Regulations did not require the fire-retarding performance of these duty windows. While, some Classification Societies(such as ABS) require that these windows must be of safe type, i.e., although broken, segements of glass should not fall down to the ground--they still remain their original shape and size. So the glass must be inserted with mini steel mesh, or, the glass can be covered with a transparent film.
This 'safe' concept is absolutely not coincide with what we knew, the concept of 'safe toughed glass'. Anyway, this is what glass manufacuturers concern with. You just take it easy. |
