Is it permitted by NEC to use a conduit reducer in an underground installation of PVC? We would like to reduce from 2 1/2" to 2" PVC for an underground service conduit system.
Thanks Sir. Actually I am part of the builder and not of the design. Base from the FALAR, NFPA 101 is the guide. The connection of the two towers is by a common/consolidated lobby at Gf and 2f. This means that the existing has no approved separation from the addition. The building has no separation at all, technically. So, QR for the new. The…
The local fire department wants a 2012 record of completion. I have searched and can only find a 2002 version. Is there a 2012 version and if so, does anyone know where I can find it?
A office manager is telling their staff to allow wheelchair bound persons access to the elevator during a fire as long as office personnel inform firefighters on the egress floor. This is a non-ambulatory office building on a hospital campus. Is this valid?
I re-read your post. It may just change my response. Please let us know your thoughts of a "...non-ambulatory office building...". Literally it may mean: not able to walk about in a place in which a professional person conducts business, but it seems you may have another meaning. I apologize that I did not read your post closer.

IBC 2015 Fire Service Access Elevator 3007.5.2 Hoistway Lighting The code clearly indicates hoistway lighting is required to be active during fire-fighters' emergency operation, however, it provides no guidance on how this "switching" is achieved. Any insight on how this should operate/function is helpful. The only guidance I have found… Show more
Response received from the AHJ so ultimately FA/Elevator coordination, but design needs to give guidance as such. Thanks for all the feedback. The GC needs to work with the fire alarm and elevator contractor. The lighting needs to come on automatically when the elevator is placed on fire service operation whether by the fire service key switch…
What would the hazard occupancy be for a Food & Nutrition Lab or Home Economics room in a K to 12 school? The appliances are all electric and there is no fuel fired appliances in the building. The ranges are all standard house hold appliances. Basically it is a teaching classroom. Can this room be considered a light hazard occupancy or should… Show more
I agree with your assessment for LH. In my opinion, it does fit the use and conditions for ordinary hazard occupancies Group 1 as described because of no bulk storage. I do believe the best fire prevention is to have a kitchen fire safety program that must be learned by teachers, who instruct the students before and during the use the cooking…
