Is it too hot to work?
Find out about the basic factors that cause discomfort in the workplace and what the law says
This site explains the concept of thermal comfort, and contains specific advice on heat stress, dehydration and cold stress when working at very high or low temperatures.
Health and safety made simple
This site is for employers and those who want some basic information on what they must do to make sure their businesses comply with health and safety law.
Thermal comfort
Outdoor working
When working outdoors, the effects of the weather can potentially have a very serious impact on an employee's welfare.
Cold stress
HSE does not have specific guidance for working in cold environments where temperatures are below 13°C. In such situations you will likely be complying with the law if you work in accordance with British/European Standards but you can demonstrate compliance by alternative means.
Heat stress
Heat stress is an issue for people working in high temperatures all year round (eg bakeries, compressed air tunnels, foundries). But this information can also be used during the summer months when there can be an increased risk of heat stress for some people.
