yeah, very dumb & selfish way to carry the tank for the safety of others (& to carrier). at least to his behalf, the tank was transported vertically (a state law at least in mine)...another safety issue...if he had "broken" the safety code (for my state of arkansas) & carried it horizontally inside the vehicle rather than as illustrated, would it have been safer for driver & others? just a rhetorical safety question...when filling my 100# tanks, i have to carry them according to code (vertically)...what are the safety issues transporting propane tanks horizontally? something about valve failure? does this apply to acetylene & O2 tanks too? i always abide w/o question, & do not endorse in any way transporting tanks horizontally (although i did many years ago unknowingly before the vertical transport law went into effect.... the challenge carrying tanks vertically is stability & tie down as in this case, plus location! reckless homeowners push the safety envelope. just a thought glad no one was hurt.
