a small fire in an old warehouse can be fanned into an explosive one by efforts to extinguish it
if those efforts blow large amounts of dust into the air where it combusts and spreads the fire through the air in a flash.

이게 한문장인데요
if 가 어디까지 이끄는지.. 중간에 into the air where it 쭉.. if이후부터가 잘 안잡힙니다
부탁드리겠습니다ㅠㅠ
