Cory, the 13 handbook explains it a little better, saying it is because storage can be put under the lowest landing and thus the requirement for a sprinkler at top as well as under the lowest landing, exhibit 8.29 of the handbook shows where the head is required.

I do not think it has anything to do with a access panel. I put the sprinklers in the ceiling at the top of the shaft and under the first accessible landing.

The spec for the job states that "Sprinkler shall be installed at top of shaft. Space below first landing is considered concealed, non-accessible, non-combustible, and hence does not require sprinkler protection." he engineer who is reviewing my plans sent me an email stating the following: *8.15.3.2 Noncombustible Construction.* *8.15.3.2.1 *In noncombustible stair shafts having noncombustible stairs with noncombustible or limited-combustible finishes, sprinklers shall be installed at the top of the shaft and under the first accessible*landing*above the bottom of the shaft. We always took this to mean the sprinklers are required under the first landing? And by accessible we took this to mean access could be provided by a access panel.." Is this the way I should be interpreting the code? Do I still have to sprinkler under the landing and make sure there's an access hatch? or should I be able to omit it like the spec indicates? I have been following this forum for a while now. This is the first question I have posted. - Cory _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) This email and any attached files are confidential and intended solely for the intended recipient(s).
