Hi, i need to know something about the explosion risk of gasoline. I have to assess the risks of gasoline leaking into a sewer. They say the vapor can cause explosions. I looked up some facts, but i can't find the answer. 1) Here's the data temperature: 2 to 10°C explosion boundaries of gasoline (in volume% with air): 0,6 - 8 vaporpressure of gasoline at 20 °C: 50-400 mbar relative mass of air saturated with gasoline at 20°C (air = 1) : 1,15 2) Question: Can gasoline vapor explode in these conditions? What will be the % of gasoline in the air? If it doesn't explode under these conditions, under what conditions will it explode?
