Blower on/off during refueling

I saw a question asked on another forum. I have always had the blower on during fueling. After seeing the response & doing a little research, it looks like you should not have the blower on. Thoughts?

    Always had mine off and ran it 4-5 minutes after fueling/before starting.

    Blowers OFF during refueling.  The blowers can pull gas fumes into the engine room.  
    I'm like @zaverin1 - I always smell the blower outlet before I turn the key.  Call me cautious, but I know exactly how the exhaust should smell.  If there's a leak of any sort -- fuel, oil, coolant, holding tank -- I'd know it immediately.

    Always OFF when fuel is flowing.

    on the gas dock 40yrs ago we left blower on..raise a hatch or pad.
    about 10 yrs ago i was told to leave blower off while fueling and only use after
    something about sparks from the electrics .
    now
     what about running your generator while fueling or at the gas dock

    No generator.  The state of Maryland issues the following guidance, which is typical of most places:

    All open flames and galley stoves shall be extinguished; engines, motors, fans, and bilge blowers shall be shut down; and all ports, windows, doors and hatches shall be closed.

    I actually open my engine hatch when refueling. Just helps fumes escape. Run blowers after

    I do the same. I figure I'd rather see/smell leaking fuel before there's a large amount in the bilge.

    In a safe boating course I attended years ago, we were taught to close all doors, compartments and hatches prior to, and during refueling. The objective is to keep gasoline fumes outside of the boat as much as possible. Gasoline vapors are heavier than air and will settle to the lowest point in a space or structure. Upon completion of fueling, open doors and hatches and run engine compartment blowers. Check the engine compartment for fumes (sniff test) before starting engines, generator, etc.

    yes that's the correct procedure.

    I've been a trailer boater untill last year, I would get gas on land, drive over to the ramp, flip the blower on & start the lanch process. Never really thought about the physics of getting fuel on the water, that the blowers may pull in gas fumes. I guess it's time to refreash a boating course. Never stop learning!! Thanks for all of the comments
