Continuity mistake: When the parathion victim is brought into the ER, they go into treatment 2, but in the view from inside the treatment room when John opens the door to leave, we can see that he's actually on the opposite side of the hall facing treatment 2, which means he's in treatment 1.

When they hear the siren of help coming, Chet stands in the road directing the vehicle, and the pickup is not where it was in that earlier shot, it's now much farther down the road.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
