Hidden behind your question must be the issue that halon is out, and CO2 may not be acceptable.
For clean agents, you may find FM-200 (HFC-227), Inergen, or Novec 1230 to be potential alternatives.
Careful Wireman...it is possible to utilize sprinkler protection in lieu of the fire-resistance rating of "A" vs. "B", but Exception 2 of 2003 IBC Section 506.3 does not allow an increase in area on top of sprinkler substitution for fire protection.
It sounds like you are looking to monitor at least two conditions: Low float condition and power to solenoid valve.
Some manufactures produce a dual monitor module, otherwise you may need 2. In order to avoid installing the monitor module outside, you could run wire from the devices being...
civilsid - in Texas they may not have freezing issues, such that wet barrel hydrants would be installed (rather than dry as you describe). Therefore, it would be possible to truly evaluate the system head pressure!
I do not have the information to solve your problem, but I think it will depend on the configuration of the track.
If the track has teeth ____/\_____/\_____/\_____/\_____ (pardon my simple sketch) I would anticipate that flexible pavement would not be suitable.
If the tracks are smooth, then...
Sounds like a heat transfer/thermodynamics problem, here's my approach:
If I take a thermos of hot coffee (insulated container, no liquid movement) and place it in my freezer (sub 0deg C)...Eventually, it will freeze. I can't stop it. Eventually the insulation will pass all the heat from the...
If your "corridor" really needs to be a Corridor (per the building code), then you may not be able to reduce the fire rating of the Corridor to zero (as it sounds like is the case now) based on the presence of high-temperature sprinklers, as the corridor should probably be QR to get that...
Before the IBC, we had the UBC on the west coast. IBC's B's can be considered to be similar to UBC's N's (which meant Not rated), A's generally represent fire rated construction (i.e. 1-hour).
Pond designs I have been involved with included 12" freeboard with a 6-foot wide 6" deep overflow spillway. In the event your pond receives more flow than you anticipated, it is appropriate to plan where it will go, and how it will get there!
The provision for extensions in the section you reference is 12 inches beyond the edge of the top stair tread, and one tread depth at the bottom. It is unclear where your designer is coming up with 2 feet.
As for alternative stairs, the exception for some spaces is the provision for...
Probably true you are on his side (typical sideyards for buildings are 5 feet minimum) though it would be appropriate for a land surveyor to locate the property lines and even create a map of the fence, garage, and your drive - get your neighbor's permission for your surveyor to be on their...
However, I will say that I am aware of jurisdictions requiring 13D or 13D+ (to achieve near-complete building coverage) for dwellings that do not have adequate fire flow or FD access.
I am not aware of a jurisdiction in this area (west coast) that applies NFPA 101. It is not referenced by the I-Codes for the purpose you are describing...yet?
If you are unable to provide the FD's minimum flow, the development may need to plan to install fire sprinkler systems in the houses (NFPA 13D). This should be discussed with the jurisdiction in advance, but will need to be anticipated in the size of the laterals leading to the home sites.
The Washington State Department of Health (DOH) recommends a maximum velocity of 8fps, but permits greater velocities during fire flow conditions. This may be a way to address your concern.
"8.1.6 Maximum Velocity:
The DOH recommends that the design of distribution mains not exceed a maximum...
Based on the NFPA 13R document you referenced, I find a couple code interpretations in your favor:
1.)
Section 6.6.7.2.1 states that outside dwelling units, the design shall satisfy NFPA 13, EXCEPT where permitted by Section 6.6.7.2.1. You point out that your project can be considered to...
The extrapolated flowrate to 20 or 25psi is theoretical, as you point out cr1973, yet is where the code looks for "fireflow" in order to have a common point of reference. NFPA standards call for a 25% drop from staic to residual pressure, and a pitot reading of 10-30psi. If the static pressure...
Whether a standard, guideline, or simply rule of thumb, for fire department drafting operations I've heard that 2 feet of water needs to remain above your outlet (to prevent whirlpool effects that may introduce air into the line) and that the fire engine (if a manual dry situation) cannot draw...
