Default The "freebee" sniff test!

JRC you get the banana!

As you all know everything about a boat is expensive. That is except the tool used to insure that your boat is free of explosive gasses. It is right between your eyes. Yup, the old sniff test is not only very accurate but also free!

As for the blower... When we teach the boating class we always teach by the book. That is all electronics, including the blower are to be off. And yes this is on the test.

I, however disagree. The whole idea of venting is to keep the space below the Lower Explosive Limit (LEL). If you run the blower while refueling you are constantly removing any explosive gasses and keeping the space below LEL. If you refuel and there is an explosive atmosphere in the space when you start the blower you will be closing a 12 volt switch (spark?) and starting a 12 volt DC motor (spark?)

I know what the book says but I just don't buy it.

New question: What things make a type I PFD different than a type II PFD?
