Short answer: NO
If the plastic tubes are <15% by weight and <25% by volume then that is cartoned class IV commodity.
If the % of plastic is greater, that would be considered Group A non-expanded plastic, cartoned.
Even if it meets Class IV commodity definition, you can NOT use miscellaneous storage, because the storage area is >4,000 ft2 and likely >10% of building area (either triggers non-miscellaneous req'ts)
I am using 2002 version (what I have at home), so I'll forgo the citations, but using the fire control approach (area/density) for Class IV commodities, curve reads 0.305 gpm/ft2 over 3,000 ft2. Reduce the density by 40% for 12 ft or less storage height = 0.305*0.6= 0.183 gpm/ft2 over 3000 ft2 required which is more than OH2 (0.17@3000)
That said, if you used high temp sprinklers you could use 0.17 gpm/ft2 over 3000 ft2 (which is OH2). All that is assuming the plastic is <15% by weight or <25% by volume.
If the plastic is above these thresholds, then for cartoned non-expanded Group A plastic, shelf storage, is either 0.3, 0.5 or 0.6 gpm/ft2 over 2500 ft2; depends on roof height. >15 to 20 ft roof is 0.5 gpm/ft2.
Real world knowledge doesn't fall out of the sky on a parachute, but rather is gained in small increments during moments of panic or curiosity.
