I'm a little confused as usual about language in the new code 901.8.2 #2 & #3 are easily defined but they throw in the monkey wrench on number one. Of course understanding the construction of the building but where can I decipher "hose removal" from certain buildings. I wish they could just write something easy like Occupancy over 100 people the "hose" can be removed or something like that. Can anyone try and make it clearer?
