Extreme temperatures, fatigue and psychosocial hazards – why they matter now

As we head into the festive season, ACT construction sites face unique challenges. Longer daylight hours, rising temperatures, and the year-end push to meet deadlines can create a perfect storm of safety risks. Here’s why vigilance is critical:

1. Extreme heat: a silent threat

Heat stress and dehydration can lead to serious illness or even fatalities. Symptoms like dizziness, confusion, and nausea require immediate action.

Best practice:

• • Schedule heavy work during cooler hours.
  • Provide shaded rest areas and cool drinking water.
  • Implement acclimatization for new or returning workers.
  • Use buddy systems and monitor for early signs of heat illness.

2. Fatigue: the hidden risk

End-of-year deadlines, overtime, and personal holiday pressures increase fatigue, which impairs judgment and reaction time.

Best practice:

• • Rotate shifts and allow adequate breaks.
  • Avoid excessive overtime and encourage workers to speak up if fatigued.
  • Toolbox talks on fatigue management can reduce incidents.

3. Psychosocial hazards: mental health matters

Stress, isolation, and financial pressures peak during the holiday season. Construction already faces high rates of anxiety, depression, and suicide.

Best practice:

• • Foster open communication and peer support networks.
  • Provide access to Employee Assistance Programs (EAPs) and mental health resources.
  • Train supervisors to recognize warning signs and intervene early.

Why this is critical

• Heat-related illnesses and fatigue can cause severe injuries and fatalities.
• Psychosocial risks affect not only mental health but also physical safety and productivity.
• A proactive approach now prevents tragedies and keeps projects on track.

Action for members

• Review your WHS Management Plan for heat, fatigue, and psychosocial hazards.
• Conduct pre-Christmas safety toolbox talks focusing on these risks.
• Share mental health support contacts and encourage a culture of care.
