In this chapter:


If the temperature inside the factory feels hot or cold, it can make your work uncomfortable. But if the temperature gets too high or too low, it can also cause serious health problems. Many factories around the world are too hot.

Your employer is responsible for:

  • monitoring the temperature in the factory.
  • making sure the air in the factory does not get too hot. For many people, it is uncomfortable and sometimes unhealthy to do physical labor in temperatures over 27°C (80°F). Check your country‚Äôs laws to see if they set maximum and minimum temperatures for work.
  • installing, monitoring, and improving ventilation (see Chapter 17: Ventilation).


Your boss should also provide fresh, safe water to drink and breaks to go to the bathroom (see Chapter 29: Access to safe water and toilets).
