Standpipes in Open Exterior Stairs

6/22/2018

2 Comments

 
An existing high-rise hotel project in central Florida has open exterior exit stairs. By code and local ordinances, standpipe hose connections are required to be in the stair (hose connections on the corridor next to the stair are not allowed).

Since the project is located in central Florida (with lowest one-day mean temperatures between 25-30 degrees F, according to Figure A.10.4.2(b) of NFPA 13-2016), is there any way to still use wet standpipes and route them in the stair? Doing so could involve enclosing the standpipe perhaps in a small shaft and keeping the hoses in insulated cabinets. Or in this case is the best option just to have the standpipe be dry to completely avoid any freeze potential?

A forensic investigator is trying to determine approximate timing of events after a fire within a hospital basement. A quick response sprinkler (RTI of 50 m^1/2s^1/2), Ordinary Temperature (65 deg C) was within a room (2.2 m high ceiling) that has an initial temperature of 70 deg F and was exposed to a ceiling plume at 190 deg F traveling at 2.3 m/s. Approximately how long should it have taken the sprinkler to activate?
a. 1 seconds
b. 15 seconds
c. 23 seconds
d. 35 seconds

Milk & Juice Storage Commodity

6/5/2018

2 Comments

 
​I'm currently working on a project for a packaging factory in which there are rooms which are used for storage of Milk and Juice in stainless steel tanks that are about 1.5 m (4.9 ft) in diameter and 8 m (26.2 ft) in height.

There are about 5-6 tanks for each area (milk and juice storage). Each room is about 70 sq.m. (753.4 sqft). The ceiling height is about 11.1 m (36.4 ft). The content combustibility (i.e. Milk & juice) is low and the quantity is high. Since the height of the tanks is above the threshold of 3.7 m (12 ft), I cannot consider it to be protected by LH or OH1 curves and it should come under storage occupancy and commodity classes.

Since my exact requirement is not present in the list of commodity classes in NFPA 13, I figured it to be Class 1 per the liquid content. Accordingly, it would be under Commodity Class 1 curve in NFPA Chapter 14 Figure 14.2.4.1 (2013 Edition) and multiplication factor for density vs storage height from Figure 14.2.4.3.

Kindly let me know if I'm on the right track or if there is something which I overlooked.
