Overheating is an issue within industry, not just for those workers struggling to cope with the increasing temperatures that even a British summer can bring, but for the industry’s machinery too.

Whilst the rising heat and humidity levels create physical discomfort, they represent real danger for the electronic components of machine tools, computers and other shop equipment. Overheating and humidity can cause switch contacts to become oxidized and begin arcing. It can also cause decreased insulation resistance, leading to shorts, loss of conductivity and changes in resistance.
