Posted By Jonathan Breeze I've not heared anything more on this Jeffrey since it was raised. P'raps a trip to the TUC website would help you. I'm also not sure what it would achieve other than making it illegal to work in hot weather or in equatorial regions. I think a better way to go would be to have a requirement into the Building Regs for new builds to be fully climate controlled (i.e cooling as well as heating).

Posted By Descarte To me upper limits dont mean a thing, it does not take into consideration PPE, personal health issues, Work load, duration, air movement, frequency of breaks etc etc I think a common sense approch should be used If you are an office working doing no heavy or mild manual work in a room with good air circulation then you can work upto 30 Deg C If you are indoors and doing mild to heavy lifting in normal attire then this should probably be down to 25 Deg C depending again on space contraints duration and air movement To the extreme If you are in full overalls in a confined space doing heavy/manual work ie. replace a failed fan within a heat exchanger where it has been allowed to cool but is still over 30 deg C then you should work for 30 mins, rest 30 mins in rotation with a supply of fresh still "bottled" drinking water (bottled is quite important as it has a higher lvl of salt which also needs to be replenished lost in sweat) with a cool place to rest and recover And everything in between The problem is, employers use not having an upper limit as an excuse to tell people to get back to work when it is stiffling hot ona day with little air movements or high humidity in areas where air con is either too expensive or unable to be installed. Not wanting their employees to be able to take a day off. Trade Unions on the other hand want an upper limit to allow people to effectively walk out when the temperature reaches a certain level. Such as is with the minimum low level of 16 deg C Either way its a hot topic, mind the pun Des

Posted By Chris Pope I believe HSL have a thermal comfort predictor on the web somewhere - this tool predictst he percentage of your staff who are likely to be happy according to 5 variables - clothes worn, work done, Relative Humidity temperature and air movement if I remember correctly.
