PE Problem #15

6/21/2018

A portion of a home-improvement store has K11.2 ceiling-only sprinkler protection above double row racks. The owner is looking to store bagged charcoal (without any impregnated ignition fluid or plastic wrap) atop reinforced plastic pallets in this area. What would the commodity classification be for this arrangement if no plastics are intermixed?
a. Class II
b. Class III
c. Class IV
d. Group A Plastic

The commodity is class III - A5.6.3 Miscellaneous, however the reinforced plastic pallets raise it two levels - 5.6.2.3. So, d. Group A Plastic

It would be D because the commodity class for charcoal w/o any impregnated ignition fluid or plastic wrap would be Class III, but when you put it on reinforced plastic pallets it would increase by two classes to cartoned unexpanded Group A plastics. (NFPA 13 2016 section 5.6.2.3)

not entirely sure...but I think d). Group A Plastic??

From NFPA 13 Table A.5.6.3, "standard charcoal, bagged" is a Class III commodity, but according to 5.6.2.7, "For Class I through Class IV commodities stored on plastic pallets...the classification of the commodity unit...shall be increased two classes", which would bump this up to a Group A Plastic classification.
