Control measure Maintain visibility with operators
Control measure knowledge
Where possible, line of sight between incident supervisors and operators should be maintained. In some circumstances, using hand or whistle signals will be appropriate. Where this is considered, all personnel must be aware of the system employed and there must be sufficient personnel for it to be effective.
- Ensure they have appropriate communications for all scenarios and environments
- Maintain visual contact with responders working on structures and use agreed hand or whistle signals
