How to approve a contractor crew change across ISO 9001, 14001 and 45001
Use one pre-start check to approve a replacement cleaning crew. Confirm service quality, chemical and waste controls, and safe access before releasing the work.
When a contractor replaces its crew, have the site supervisor check the people arriving against the work they will do. Release the shift when the supervisor has evidence that the crew understands the service requirements, environmental controls and site hazards. Record who authorised the start and how they checked the work.
In this illustrative example, a cleaning contractor sends two replacements to an occupied office building. The scope and products are unchanged. The contract owner uses Plan, Do, Check, Act to test whether the approved arrangements still work with a different crew.
Plan the checks before the crew arrives
The contract owner asks the contractor supervisor for the revised roster and agrees who will brief the replacements. The site supervisor checks three points before authorising work.
- Quality. Confirm who will cover each area and who will inspect the completed work against the current service specification. Include rooms with different access times or cleaning frequencies.
- Environment. Confirm which products and dosing equipment are approved. Show the crew the site’s arrangements for storing products, managing spills and handling leftover solution and empty containers.
- Safety. Consult the people doing the work about access, wet floors and working around occupants. Show them how to report a hazard and agree who can suspend the work if the controls cannot be maintained.
Authorise the shift against the roster
At sign-in, match the people present to the revised roster. Ask one replacement to explain how they would handle an occupied room and another to show where the site instructions for leftover solution are kept. If someone has missed the relevant briefing, keep the affected tasks on hold until the supervisor has addressed the gap.
Check the work during the first shift
The site supervisor samples a room against the service specification, checks the product and dosing arrangement in use and observes how the crew manages pedestrian access. Suppose the room passes inspection and access is controlled, but the replacements cannot locate the designated place for leftover solution. Record the environmental control gap against the job and have the contractor supervisor address it before that part of the work proceeds.
Test the handover on the next crew change
The contract owner adds the location and handling instructions to the briefing and assigns a supervisor to demonstrate them. On the next replacement shift, observe whether the crew can locate and follow the instructions independently. Keep the roster, briefing record, start authorisation, observations and follow-up result together so you can trace the decision.
Apply the current standards to your scope
ISO’s ISO 9001:2026 overview highlights quality culture and leadership. Its ISO 14001:2026 revision overview explains the broader focus on externally provided processes, products and services. ISO lists ISO 45001:2018 and its amendment as the current published safety criteria.
