Inventions - S3-E22
Visible crew/equipment: At the site of the major chemical leak, after Johnny falls from the pipes and Roy lifts him up, a couple of shots later there is a medium shot of one of 105's guys on Deluge 105 pumping out water, and we can see a cameraman (filming Deluge 105's closeups that we see during this scene) holding a handheld on the right of the screen, behind the pillar.
