This ‘seal’ you speak of would not actually seal anything IMO as many inner escutcheons have a hole through them as well as the bent teeth for a friction fit for the outer escutcheon around it creating multiple ‘non-sealed’ voids. Can you use the rubber boot for the backside of dry pendants to

RE: Seismic Requirements for Risk Category IV (Essential Facility)

Risk Category determination out of ASCE-07 (2010) Table 1.5-1 drives the Seismic Design Category (SDC) based on Ss and S1 to a more severe designation in Tables 11.6-1 and 11.6-2. As Craig said, SDC should be provided for sprinkler contractors where this 'severity' has already been determined

Your building sprinkler feed is just that...a sprinkler feed which should be hydraulically calculated if minimum sizing is desired. Otherwise, A fire flow does not ONLY come through this line, it cumulative in the vicinity. Fire flows are for overall requirements of all adjacent hydrants off

RE: temperature monitoring system

Bruce, I believe Tim is referring to a reference in UFC 4-211-01 that has been out for some time in draft form which states, "Where wet pipe systems are installed in areas with a 99.6% dry bulb temperature less than 30°F (-1.0°C) per UFC 3-400-02 Engineering Weather Data, temperature

RE: Piping of radiator discharge line

Presuming you are talking about fire pump cooling operation, is this really a radiator-cooled pump or is it a heat exchanger cooled pump? Heat exchangers use the pumping medium to cool the pump and this piping cannot stagnate or cooling system will not function. Piping back to the main header

Dots and bars

Is there a reason the bars along new standard text and dots next to sections that have been removed...have been omitted from NFPA 13 (2016) and other standards...NFPA 11(2016), etc.? I for one found these to be helpful in the past when multiple editions needed to be researched to determine

RE: PVC (C900) for spigot through floor

I'll play devil's advocate: It may be allowed up to 24" as indicated in NFPA 13 (2013) Section 6.3.1.1.1* which states " Underground pipe shall be permitted to extend into the building through the slab or wall not more than 24 in. (0.6 m)." The annex for this section states "Extending the

RE: Column Protection

In this case, for column protection, we want full 'obstruction'. NFPA 13 (2013) Sections 12.12.2.2.4.1(5), 16.1.4.1(2), 17.1.4.1(2), and 18.2.1(1) all give very nearly identical prescriptions of how to protect these structural components in that they are 'pointed toward one side' of the

RE: Using Rod as brace material

As a sometimes acting AHJ I generally do not allow rod to be used in compression. ATR should not be axially loaded in compression since this can introduce the tendency to bend thus creating a lateral load which is not allowed as described in the Annex of NFPA 13 (2013) in Section A.9.1.2.3(1).

RE: Frozen open PIV

This may be more of an issue with the Indicator post not being calibrated to indicate that the valve below is open when it is in fact partially or nearly fully closed. Ran into this before. PIV installation must indicate valve to be fully open when fully open. Ryan L. Hinson, PE*, SET Fire
