Thanks for the help,guys.
Good to know that you have not been hassled about having the tanks on the forklifts,Dave. I would still be a little worried that a good jolt could release a tank strap.But,I guess there is no formal regulation in most places.

Dave,I'd like to know how your company arrived at the 6 tank limit.It seems that is well within the regulations requiring placarding,like you seem to be able to double or triple that number before you would get there.For me,I can't see me carrying more than 3 for my uses.
