    Am a bit shocked that you talk about getting into the tank and cleaning it physically, without pointing out the serious danger that goes with this, depending on the type of tank and the top opening. If the tank has the hatch type opening on top, then there is no adequate ventilation or air exchange. Once you get in, you start consuming the oxygen, and the timer is ticking. When you run out, you drop on the floor, and unless there is someone to pull you out, you die within minutes. It has been known for a fellow worker to climb in to save his mate, only to collapse on the floor and die with him. In industrial situations this is recognised as a major OHS hazard, and there must be safety measures in place. Of course this only applies when there is a limited air intake, such as the top hatch type opening.
