Definition of combustible construction?
Definition of combustible construction?
(OP)
I am in doubt weather or not a trapezoid construction as shown in the attached picture should be categorised as obstructed combustible. What would you think? And where would I be able to find a list of definitions for combustible materials?





RE: Definition of combustible construction?
OK what am I missing, I know it is early. I see concrete and metal.
Are you asking if the cieling is obstructed or unobstructed????
RE: Definition of combustible construction?
The reason I ask, is because of the trapezoid steel. In case of a fire, there is a risk that the steel will collapse. I'm in doubt if the trapezoid therefore could be categorised as combustible in the NFPA13 code.
And how would you categorise the construction shown in the picture?
RE: Definition of combustible construction?
While the term pocket ceiling is not defined in NFPA 13, this appears to be case where I would evaluate the design based on Section 8.6.7.1 of the 2002 edition.
