Question 1: A home owner leaves a 5 gallon can of gasoline(specific gravity 0.73, LEL 1.4%, TLV 300 ppm, mw 108) in his attached garage (25 ft x 20 ft x 7 ft). If 10% of the orginal volume of the can evaporates per day and the volumetric air flow rate is 2 cfm, what hazards are present in the garage? assume perfect mixing (K=1) and the garage reaches a steady state.

Does the concentration of gas exceed the TLV of 300 ppm?
