Well, as long as he's done a JSA (job safety analysis) and is following the SOP (safe operating procedure) and has the right training (done by someone who is trained as a trainer, but not necessarily trained in the SOP) and has filled out a START that is cosigned by a colleague and is wearing the correct PPE then he should be fine.
Just a photo of what he is doing is useless, The paper work decides if it is safe or not.
Ain't that the truth!
I'm always amused at how someone who doesn't know how to to a job (but has been told how to do the paperwork) can be the judge of whether something is safe or not.
Safety people are good up to a point at which they start looking around trying to justify their own jobs. Then they are just a massive pain in the arse!
