Working during hot weather

30 July 2024

​​​While there is no maximum temperature in law at which it is too hot to work, employers must improve thermal comfort where possible.

An acceptable working environment is dependent on a number of variable factors including:

• air temperature and humidity
• air movement
• nature of the work

Consideration should include:

• encouraging employees to drink plenty of water to avoid dehydration
  
• evaluating dress code, including type of PPE worn
  
• consider altering working hours to start and finish earlier
