Thanks Stookey. Here are some follow up questions based on your responses.
1. Are there any particular high school chemistry books or college organic chemistry books you recommend that you typically use for your hazmat projects?
2. You mention water solubility. Is this synonymous with water...
Hi, a few inter-related questions regarding Flammable Liquids:
1. What are the best books/websites/other resources are there for reviewing an MSDS sheet to make an accurate determination of the water miscibility for each component chemical in the list in order to comfortably classify the...
Thanks cdafd, your link was an informative read. I also received some feedback from the NFPA and thought it would be best to post here for the benefit of others:
My response is based on NFPA 101, Life Safety Code, 2015 edition.
No - the requirements for emergency lighting in storage...
Hi, are there any situations in the NFPA 101 (other than the exception in §42.2.8.2) or the California Fire Code where emergency power is not required the designated path of travel? For example, are there any warehouse conditions where emergency power is not required and a designated path would...
Hi, I am designing a "designated" exit path in a storage rack warehouse so the electrical contractor can determine which lights are required to have emergency power to meet the minimum 1-foot-candle requirement. I have included a 44" wide "designated" perimeter around the racks themselves, and...
Thanks for the responses. To be clear, I am specifically referring to the scenario where the building is non-sprinklered (so not ESFR where Note j would apply), and IS high piled storage.
My question did include my own answer of the scenario in which I've outlined... I am really just looking...
Hi,
CFC Table 3206.2 calls for the use of draft curtains in non-sprinklered buildings. In what capacity would they actually be required? According to Table 910.3, draft curtains must contain a floor area of 10,000 SF max. for Class I-IV commodities <= 20' top of storage. My understanding is...
LCREP, I am waiting for a response from my FPE on this as well, thank you for the insight.
skdesigner, thanks for the direction as well on FMDS 8-7. I wish it included hay just to have a clear answer, but this is great. With a combination of FMDS 8-7 and other supporting materials, we can...
Hi,
We reviewed a metal framed building that stores 4'Wx8'Lx3'H bales of hay in grouped stacks, and they are looking to stack upward. The two high piled storage areas have a CMDA design density/area of .35/2,940 (Area #1) and a CMSA design of 25 heads @ 25 PSI (Area #2).
The 2013 California...
Hi,
I have a client that is storing stable unexpanded cartoned and exposed Group A plastics on single and back to back shelving units (not storage rack) with wire decks and solid shelving (which they are willing to remove if it helps). They have a 28'-6" ceiling height and top of storage at...
I found a very interesting article on the historical forming of the NFPA 13 design area curves:
http://magazine.sfpe.org/sprinklers/nfpa-13-sprinkler-system-design-density-curves-where-did-they-come
I have crunched through it and found very interesting points that really put the curves into...
Hi cdafd, thanks.
Yes, but I was more concerned about flammable and combustible liquids, which are still high hazard, not Group A plastics. It would be nice if they had a table like 2303.7.4 for F/C liquids.
Thank you
Hi,
According to the 2010 CFC, this is the definition for High Piled Storage:
HIGH-PILED COMBUSTIBLE STORAGE. Storage of combustible materials in closely packed piles or combustible materials on pallets, in racks or on shelves where the top of storage is greater than 12 feet (3658 mm) in...
