I am not sure which code you are operating under, but UBC does not allow any
penetration of stair enclosures other than for pipes and conduits
specifically serving the stair enclosure. (1005.3.3.5)

	The National Fire Protection Agency's voluminous books on the
subject takes 
	quite an effort to comprehend, like any other regulatory document.
A have a 
	simple question, for which I have not yet found an answer.  When a
structural 
	steel member passes through a firewall, is there a requirement to
seal the 
	gap between the steel member and the block masonry firewall? If yes,
what 
	material should be used? Shouldn't the sealant be capable of
allowing some 
	expansion of the steel member (due to heat by conduction)? The
firewall 
	separates an egress stairwell from a process area.
