Safe Working Temperatures

Safe Working Temperatures Cold Hot

Safe working temperatures are important in any workplace. Low temperatures, for instance, can be uncomfortable. A cold atmosphere creates dissatisfaction and complaints. Few people can focus properly on their work when they’re trying to stay warm.

Furthermore, in a cold workplace, staff may put on jumpers and jackets. In a shop, these may not fit with a retailer’s brand image. And in an office, heavy clothing can restrict movement when using computers.

At the other end of the scale, excess heat can cause drowsiness. This in turn may lead to sloppy or unfinished work. High temperatures cause Heat Stress and other health problems.

Minimum Temperatures

The minimum safe working temperatures recommended by the Health and Safety Executive (HSE) are 13ºC and 16ºC.

The first of these applies to a workplace where there is physical activity. Such activity could be loading and stacking in a warehouse, or mobile work in a factory.

A minimum temperature of 16ºC applies to a sedentary workplace. This could be an office environment, a call centre or a public reception area.

Maximum Temperatures

Despite the difficulties associated with hot working environments, there is no legal maximum safe working temperature. The only requirement is that workplace temperatures in buildings should be reasonable. This condition appears in the Workplace Regulations 1992.

The Trades Union Congress (TUC) has gathered many examples of the effect of high temperatures. During hot summers, for example, employees are more prone to trip or slip. And those staff that work with computers often suffer from stress, tension and tiredness.

For manual workers, the effects of working in hot conditions are just as bad. The TUC has reports of fainting, dizziness and cramps. For some workers, the heat also places a dangerous burden on lungs and hearts.

Other common medical conditions associated with working in overheated workplaces include asthma, throat infections, and rhinitis.

Recommendations

In the absence of a legal ruling, the TUC has recommended maximum safe working temperatures. These are 27ºC for manual workers, and 30ºC for sedentary workers.

Controlling High Temperatures

In an office, employers may be able to keep the maximum temperature below 30ºC. They can do this with suitable ventilation and shades.

Suitable ventilation can take the form of air conditioning, open windows and fans. These measures can help to keep the air fresh. Stuffy air interferes with workers’ concentration, and can raise the temperature to uncomfortable levels.

If employers use air conditioning, they need to ensure that engineers regularly service and maintain the systems. Badly functioning air conditioning has led to examples of increased rather than lower temperatures.

Employers can also make staff more comfortable by allowing a sensible dress code and by ensuring there are regular breaks for cooling drinks.

Controlling safe working temperatures for people doing manual work outdoors in the heat is more difficult. The TUC suggests that such workers have regular breaks and drink a lot of water. It also proposes that management arranges for workers to rotate to jobs in shaded areas whenever possible.

Controlling Low Temperatures

In an office or shop, the obvious way to maintain the minimum safe working temperature is by using heaters.

For outdoor manual workers, employers should supply adequate warm clothing. Manual workers should also have frequent hot drinks.

Hi, I work in a warehouse, big shutter door always open, no heating at all.. I have asked if we could have heaters by our workstation but we're told no as the electric would cost too much as it would take forever to warm the place up.I'm dreading January as last year it was -4 inside the warehouse... What can I do?

I have staff that secure a car park for a university. There is a gatehouse for them to sit in but there is no heating because the generator is broken. With the temperature dropping as much as it is should I contact the HSE? My guys man the car park from 0530hrs until 2245hrs.

I work in a shop where the heating broke in January and the area manager's only response was "jog on the spot" we have no heating on the shop floor and customers always complain about it being too cold for them, staff were frequently having to wear coats throughout the summer and now that it is approaching winter even with coats and thermal layers the temperature is becoming even more unbearable. Is this a reason to contact HSE?

Hi I work in a small convenience store and our air conditioning has been broken for the last 2 weeks. The store temperatures have reached 40 degrees + and customers can’t bare to stay inside for longer than 5 mins. Managers aren’t racing to do anything except allow us free drinks and we’ve brought fans in from home but neither of which make any different when doing a 10 hour shift in such a hot environment. I understand there’s no legal maximum temperature but I have heard of bigger shops closing temporarily due to similar problems? How would this come about as I don’t know what the next step should be for us working there?

Hi I work in a very hot and humid environment in the summer temperature at 6am is always above 33 degrees climbing to 40+. We have just been made aware that the company have not carried out a risk assessment should the by law complete this.

Our Response:
All companies should have a risk assessment that identifies any potential risks to employees. Make a formal complaint to your employer or contract HSE.

Dotti - Your Question:
Hi I work in a part of a factory with no windows and up stairs I have two fans which are constantly blowing hot air around the temp at the highest has reached 39 and lowest 36 I had to take some holiday to have a day off from the heat as I find myself by 2pm confused and cant think straight although I finally got an air conditioning unit but unfortunately the temperature dint go below 34 and couldn't feel the benefit unless I was sat right on top of it, is working in this sort of heat ok? And I feel like why should I have to take my own holiday as I will be penalised for having a day off due to what the heat is doing to me at work

Our Response:
Talk to your employer about the effects of the heat on your performance. Your employer has a duty to make a suitable assessment of the risks to the health and safety of their employees, and take action where necessary and where reasonably practicable. If you do not feel your issue has been listened to, you can raise a formal grievance, ACAS can help with this if you do not have a formal grievance procedure.

I work cleaning buses in all conditions it don't matter if it's too hot or too cold .they don't seem to care .there answer is you work out sideso it is more or less so get on with it what are our rights
Maxi - 26-Jul-18 @ 2:21 PM
The fan does not make any difference as blowing out hot air as too hot. We do get water breaks, but when its constantly hot in the factory next to hot machines its difficult

Hi, Work in a coffee factory where we roast and grind coffee.We have to wear ppe due to hygieneWith all this hot weather its causing us to sweat by 7am. What can we do? They have given fans which can only do so much in this heat.Asked for extra 15min break which they deem is not needed.

Our Response:
If the employer deems 15 mins is not necessary then be sure you are allowed to drink cold water when necessary/on the job. Are the fans making any difference?

J - Your Question:
I work in retail, no air conditioning. (because the building isn't made for it apparently) there is something that blows air into the building, but it's 99% warm air. We get given water VERY rarely, but it's warm water, no extra breaks given. I feels like its 30+c, we are still expected to do the same amount of work, alot of us feel ill. Ive tried speaking to managers and they dont really seem to care much, says it needs to 40c before we can go home!

Amzz - Your Question:
I am 25 weeks pregnant and I am a cook in a busy canteen inside a factory, the temperature in the kitchen has started to hit 40 degrees and I am really starting to suffer, our air con doesn't barely work and a fan they have brought in is no use. I am completely exhausted tonight I couldn't even make it up the stairs when I got home because of the heat. Do you have any advice because I'm aware that there are no upper limits on workplace temperatures in place and I am worried about the safety of my unborn child.

Our Response:
Please check our guide to being pregnant at work which explains that your employer must carry out a risk assessment of your job to identify any possible risks to you and your unborn child. Your employer is then obliged to take reasonable steps to either remove the risk, or remove you from the risk (for example, by offering you suitable alternative work). If neither of these options are possible, your employer should suspend you from work on full pay.

Can you advise if employers are obliged to ensure that long distance wagon drivers have air conditioning in their cabs for these extreme temperatures.

Our Response:
There is nothing that specifically mentions the provision of air conditioning for long distance drivers butManagement of Health and Safety at Work regulations say that all employers have a general duty to protect the health and safety of the workforce under the Health and Safety at Work Act, and also to assess and control risks from working in hot temperatures, or exposure to the sun etc.

Sweatyworker - Your Question:
Hi,I work in a locked mental health rehab. Windows have restrictors and doors are locked. We have no air con and our estates team have rejected our application for it. One of our patient bedrooms is 31degrees and other areas vary between 29 and 31 degrees. Myself and my team of housekeepers are doing a very active job and are finding it unbearable to strip and make beds, mop and generally clean. Offices are hot too as they are very small and some have no windows that open. It beggars belief why there is no maximum temp in certain sectors. Surely for a mental health rehab this heat is doing our patients no good. Everyone is lethargic and agitated!! I have an ongoing health issue to called Crohns disease where I struggle to stay hydrated, I'm trying to drink enough but I'm sweating far more than I'm drinking. Any advice?

Our Response:
If first line management has refused then refer to senior management. If that doesn't resolve your issue, raise a formal grievance with your employer. Talk to ACAS for advice on taking it further if you feel your health and safety is being severely compromised.

T - 9-Jul-18 @ 6:04 PM
We are working in a kitchen at a busy college, the temp has been unbearable. The supervisor doesn't feel the heat she feels the cold. ( she needs to eat) we are suffering being short staffed and running around like lunatics. Thurs this week I almost passed out and all I got from my boss was a shrug. I take iced drinks into work and also wet wipes as to stop me perspiring all the time. Sorry to moan but could do with some advice.
