Therefore, will you please return to them any unused jugs which you may have on hand. Several of our safety men Iiave been allovring refiners to talcs their own sludge and scale samples from the inside of storage tanks. I think our safety men can take these themselves in almost every case and this is the desirable way of handling it. In cases where two tanks are cleaned at different 30laces at the same time, it may he ^possible to delegate this job to some refinery man, but this should Gnly he done where you have confidence in the man that is to take the samles and can exolain to him how this work is handled.
