Night working on construction sites creates communication challenges that do not exist during daylight hours. Reduced visibility, smaller crews, fatigue, and limited supervision all increase the risk of miscommunication and error. Reliable communication protocols are essential for coordinating tasks, maintaining safety, and ensuring an effective emergency response after dark. This talk covers the communication methods and rules for night working.
Key Hazards
Miscommunication between operators and ground workers in reduced visibility
Delayed emergency response due to poor communication systems at night
Fatigue reducing alertness and the quality of verbal instructions overnight
Radio or phone battery failure leaving workers unable to contact supervisors
Control Measures
Issue two-way radios to all key personnel and check they are fully charged before each night shift.
Establish a communication check-in schedule with all work teams at regular intervals throughout the shift.
Agree standard radio protocols including call signs, channel numbers, and emergency keywords.
Ensure a dedicated channel is available for emergency communications separate from routine traffic.
Brief all operatives on the communication plan, emergency contacts, and reporting procedures at shift start.
Use illuminated signage and hand signals where verbal communication is not possible due to noise.
Carry a backup mobile phone with the supervisor's number stored in case of radio failure.
Record all safety-critical communications in the night shift log for handover to the day team.
Remember
Two-way radios must be issued to all key personnel and fully charged before every night shift
Regular check-in calls with all work teams must be maintained throughout the overnight shift
Standard radio protocols including call signs, channels, and emergency keywords must be agreed
A dedicated emergency channel must be kept clear and separate from routine radio communications
Every operative must be briefed on the communication plan and emergency contacts at shift start
All safety-critical communications must be recorded in the night shift log for day team handover
