With the warmer temperatures across Ireland this week, it’s a good time to think about heat stress and how warmer conditions can affect people during their working day.
While outdoor work is often the first thing that comes to mind during hotter temperatures, many indoor work environments can become just as challenging, particularly areas involving machinery, production lines, physical tasks, limited airflow or heavy PPE.
During warmer weather, temperatures can rise quickly indoors, especially in busy environments where people are constantly moving, lifting, operating equipment or working near heat generating processes.
Heat stress happens when the body struggles to cool itself properly. Even moderate temperatures can lead to fatigue, dehydration, reduced concentration, and slower reaction times all of which can increase workplace risk.
Some common signs to watch for include:
- Headaches
- Dizziness
- Excessive sweating
- Fatigue
- Muscle cramps
- Nausea
- Difficulty concentrating
A few simple steps can make a big difference during higher temperatures:
- Encourage regular hydration
- Improve airflow and ventilation where possible
- Allow for additional short breaks during physically demanding work
- Rotate tasks where heat exposure is higher
- Check in regularly with staff
- Encourage staff to report symptoms early
What steps are you taking this week to help prevent heat stress?
Enjoy the sunshine and stay safe! ☀️
