The extent of supervision depends on the risk and the ability of the mobile worker to identify and handle health and safety issues.
Employees new to a job may need to be accompanied until competencies are achieved. Supervisors may periodically visit to observe the work being done.
There should be regular contact
Automatic warnings should be activated if mobile workers do not return to base within the appropriate time
Other warnings that raise the alarm in the event of an emergency should be devised
Check that the mobile worker has returned to base, or home, on completion of the work.
