The Wedsworth-Townsend Act - S1-E1
Visible crew/equipment: When 127's snorkel is raised to rescue the man who was electrocuted atop a utility pole, as he's being loaded, in the first closeup within the snorkel, we can notice two things. We can see someone wearing denim at the left of the screen between 127's guy and Johnny, and we also see the ground past Johnny's head. Then as the snorkel is still being lowered, in the shot from the same POV, once again at the left we see that crew member wearing denim, who is outside the snorkel basket, and also see the ground, but the ground has not changed. This reveals that these two closeups were shot at ground level.

Visible crew/equipment: On site at the construction accident with the back injury victim, when Roy climbs over the tower's railing we can see the yellow canvas strap attached through the leather loop of his lifebelt, but when he descends to the injured victim, the yellow canvas strap is now also attached to a carabiner protruding from under his turnout coat, by his pants, which presumably is attached to additional hidden support.
