Okay now the diver moves on now searching for a small child.  Now to the first barrels.  At this point the diver will realize that it is impossible to fit through the tubes with all gear on.  The diver will need to take off their dive gear.  The diver now has to push the dive gear through the barrels while they follow...they are still breathing off of the regulator of course. Once through the barrels the diver has to put all the gear back on.
