Check-In Communication Procedures

TBT-LON-017

Regular check-in communication is the primary safeguard for lone workers on construction sites. If a lone worker is injured or incapacitated, the check-in system ensures their absence is detected quickly and help is dispatched. A missed check-in triggers an escalation process that could save a life. This talk covers how check-in procedures work and why every lone worker must follow them without fail.

Key Hazards
Lone worker incapacitated with no one aware of their situation
Delayed rescue from missed check-ins not triggering the escalation procedure
Communication failure in areas with poor mobile or radio signal coverage
Complacency leading to check-ins being skipped or ignored over time
Control Measures
  • Agree the check-in interval and method with the nominated contact before lone working begins.
  • Set check-in intervals appropriate to the risk level, typically every 30 to 60 minutes.
  • Use a reliable communication method: mobile phone, two-way radio, or lone worker device with GPS.
  • Confirm the escalation procedure if a check-in is missed, including who is contacted and when.
  • Test the communication equipment before starting the lone working task to confirm signal strength.
  • Set reminders or alarms to ensure check-ins are made on time and not forgotten.
  • Never skip or delay a check-in even if the task is going well and you feel safe.
  • Report any communication dead spots to the supervisor so alternative arrangements can be made.
  • Brief the nominated contact on the lone worker's location, task, and expected duration.
Remember
  • Check in with your nominated contact at every agreed interval without fail
  • Test your communication equipment before starting any lone working task
  • A missed check-in triggers the escalation procedure so never skip one even if you feel safe
  • Report any communication dead spots so alternative arrangements can be put in place
  • The nominated contact must know your location, task, and expected finish time
