A contractor induction is the safety briefing and acknowledgement a contractor completes before starting work. It typically covers site hazards, emergency procedures, permits and any site-specific rules, and ends with a recorded acknowledgement.
Running it through a visitor management system means the induction happens at sign-in rather than on paper, and the record sits alongside the visitor log. Contractors who completed it recently can be waved through; those who have not are blocked until they do.
Common on construction, manufacturing and healthcare sites, and increasingly expected in offices where contractors work outside normal hours.
