Thank you!

Hi Experts, The building exterior that I want to install my new louvers are very close to another property (closer than 4 ft). Two new louvers one for outdoor air intake one for exhaust. They are ducted to new ERV in my space. Can anyone please let me know if my louvers need to be...

It's in Canada, Ontario.

Hi cdafd, The fire pump was tested. The technician simply attached two different nozzles (1/2”, 3/4”) to existing 75 ft hose during test and had pump pressure, nozzle pressure, hose residual pressure, calculated GPM recorded. The existing fire hose is standard 1-1/2” hose with 1-1/2” hose...

Hi guys, I want to determine if I can replace a 75’ hose to 100’. The fire pump is located at P1. The pressure test was performed based on existing 75’ hose. Now I have the numbers of static pressure, nozzle pressure, hose residual pressure and calculated GPM. What is the best approach to...

cdafd, Thank you. I looked for 9.3.16 from 2019 but it refers to skylight :)

cdafd, Thank you. I'm pretty much sure sprinkler is not required within such glass enclosed space. Found some pictures showing similar full glass vestibule: https://www.pinterest.ca/pin/360850988892092826/...

cdafd, I see, but I'm not sure if it is applicable for my situation. I think my vestibule is interior? As it is inside of exterior wall while 8.15.7.2 addresses exterior projection, like a walking canopy?

Hi, I've been reading but couldn't find an answer for this. We have a new vestibule for a retail space on ground floor. New vestibule is surrounded by glass partitions with 11" high base below the glasses. The ceiling is glass as well. There are also electric base-board heaters that will be...

Travis, Sounds right. It's light hazard, and each suspended flat is 8 in. width. The top could be 18" below the higher T-bar ceiling. Sprinklers are at the higher ceiling. Sprinklers are standard spray, standard coverage sprinklers. It just seems to me that they can still interfere with...

I see. Thank you @UFT12

Right, and it's more than 70% open. I'm now just cannot find a certain clause for this situation, to make me safe... Apparently these dangly things are not considered as open-grid (8.15.14) nor suspended vertical obstruction (8.6.5.2.2).

Hi @cdafd, That will be a typical open-grid without any problem I believe... With those dangly things, I'm not thinking that my situation can be considered as open-grid ceiling now.. they are so deep and will interfere with the spray pattern. Also an issue about the heat & sprinkler activation.

Thanks for this very clear and thorough explanation @UFT12. I understand what you said and the architect is most likely willing to provide me necessary clearance needed. What I'm really confused now is, 8.6.4.1 requires 12" max. from the deflector to the ceiling. 8.15.14.1.(2) requires 18"...

Thank you!

One thing that I was really confused was: If I have less than 18", for example 15", between suspended ceiling and primary ceiling, per Section 8.15.14, I will need to install beneath sprinkler heads. Does that means I will need to bring down pipes to make some new pedant sprinkler heads...

Thank you guys @cdafd, @ UFT12. Some answers that I know: 1) The distance between each row is about 12". The total length of one row of suspended rail that these flats will lay-in is 180". Each row of rail will have 10-12 flats. 2) The flats are rigid and they achieved a Class A Flame Spread...

Hello gents, I'm working on a office renovation project that involves a large number of suspended architectural acoustic flats/baffles installed in a meeting area. Some details of the situation: 1. All flats will be installed on rails from a suspended ceiling system. Distance between...
