Two sets of obligations meeting on one floor
Your site controls the environment and the induction. The provider controls their people, their equipment and what those people are instructed to do. Both sets have to work together, and a comparison that only covers your requirements leaves the other half unexamined. The question is not whether the provider will accept your rules but whether they have any of their own and whether those rules reach the person who actually attends.
Ask what their staff are told before attending an operating industrial site for the first time. Pedestrian routes, high-visibility clothing, eye contact with plant operators, exclusion zones, what to do if an area becomes active while they are working in it. A provider who describes this readily has briefed people before. One who does not will rely entirely on your induction to do the work.
