Ventilation in the Workplace

Ventilation In Workplace Workplace

Ventilation in the workplace is covered under the Workplace (Health, Safety and Welfare) Regulations 1992 which states that workplaces need to be adequately ventilated in the proper manner by which clean air is drawn from an external source outside of the workplace and circulated throughout the building. Whether by natural or mechanical means, it should dilute and remove humid air and provide sufficient air movement to give a feeling of freshness without causing a draught.

What Else Do the Regulations Cover?

As well as providing sufficient fresh air to breathe, the regulations also require that a workplace can successfully remove excess heat or, in some cases where it’s air conditioned, provide heat if necessary. A company must also ensure that any odours from food or any excess contaminants such as dust and fumes are properly removed. In some cases like a small office, for example, doors and windows may well be sufficient to comply with the regulations but in larger premises such as an industrial factory, mechanical ventilation will usually be required.

Providing the Correct Temperature

In addition to proper ventilation, companies also need to ensure that their workplaces are maintained at an appropriate temperature. Of course, when it comes to temperature, it can provoke a very mixed reaction from staff as some will feel hotter or colder than others when working in exactly the same building but the general guidelines are that workplaces should be kept at a temperature of at least 16C (61F) where most of the work is sedentary and at least 13C (55F), where the work involves more of a physical exertion. There are, however, exceptions to this.

Working in Hot or Cold Environments

There are many jobs in which you’ll be required to work in temperatures either above or below those recommended above. To comply with health and safety regulations however, a company must carry out a full risk assessment taking both personal and environmental factors into account.

Personal factors might include the physical extent of the job, the type of clothing worn and the length of continuous exposure to a given environment. Environmental factors could include the ambient temperature, radiant heat and, if the work is performed outdoors, things like direct sunlight, wind and possibly rain and snow will also need to be considered and appropriate provisions put in place.

Situations where these kinds of factors will need to be considered can include working in cold storage centres, food preparation e.g. kitchens, bakeries, foundries, launderettes etc. and adequate provisions will need to be put in place to eliminate or minimise the effects of working in extreme cold or heat.

This might include installing cooling systems, fans, heaters in fork lift trucks in cold stores, for example, and even an employee will be entitled to an adequate number of rest breaks and/or time away from working directly in the exposed environment. Suitable clothing and changing of clothing provisions will need to be in place and employees should also receive training, acclimatisation and medical checks to ensure they are fit enough to work in such extreme conditions and to be able to benefit from ongoing medical screenings.

Recently my workplace install all the machinery into a small factory..but the result is that with all the cutting and cooling fluid being thrown into the air...As well as wood dust from the other saws.. it's almost painful to breath sometimes and all you can taste is acrid cutting fluid...The factory is usually filled with a hazy smoke.. Employee just shouts at us if we complain stating the fluids don't havean irritant coshh sticker so it's safe.. Add to this the fact that the other day every machine with a small extraction failed an inspection... But are still being used... Seriously concerned for health risks..any advice please?.

Work with heavy printing presses. Enclosed space air conditioning units are situated inside and venting polluted air in to our work space. No ventilation system for pulling out the polluted air and pumping in fresh air.

Hi I work in a factory of about 30 people so it is not a massive factory, but we have 7 cnc milling machine and 4 cnc turning machines and we also have a lot more equipment but we don’t have any extractor fans or ventilation, all we have is a door that used to open but as we’ve got a new machine and this machine does all the hardest parts the door can not open as it’s been placed right next to it so the temperature changes in the machine and this has to stay the same. It has been like this before Christmas, when we came back from our 2 weeks off over Christmas our heating wouldn’t work as there was so much dust on them that it had to be all cleaned and that just shows what we must be breathing in, in our factory. Is there anything we can do to get this fixed as our owner doesn’t seem to bother. We also have a water cooler but it doesn’t get cleaned properly and it’s our only source of clean water in work but no one comes in to check the filters or cleans it properly.

Been working in an open office which used to be a dairy years ago. Some morning you walk in and the smell is so over powering it makes you heave. I have had to go to the toilets to vomit the smell turns your stomach. Is this safe working conditions to your health? The smell goes after about 1 to 2 hours but worried what we are breathing in in those hours until the air con kicks in.

I stock overnight at a Walmart, and am often made to work in Pets (every day for the last 3 or 4 years). The air conditioning in that corner of the building is incredibly poor, which makes it the hottest corner of the building, and becomes even worse on hot days. I get heat stroke very easily, and any time I report on it or ask to be removed from stocking Pets due to the conditions, I'm told I'm "making up excuses" and promptly ignored. Many others complain about how warm it is over there as well as the poor air conditioning system.

I was a chef at a hotel, where the extractor fan broke down, bear in mind all my equipment cooker, fryer, and grill are gas, we got made to work In a busy small kitchen like this for 2weeks, and got told we had to work, after that was fixed it happend again and same situation, when I mentioned this to the owner, he said we are not shutting the kitchen because the gas still works, ungreatfull in my eyes that an employer can do that

Hello I work in a box factory. And I work on flyer machines. Witch they have to heat the glue. Witch raises the temperature. And it is manual labor. Packing and stacking heavy boxes. That also raises the temperature. There is cardboard dust everywhere. But there is no windows open. And the last 3 weeks they have been shutting off the air conditioning. Its to hot to do that. I feel like I'm drowning in sweat now. Everyone is miserable. And all they can say is. We shut it off to cut costs in company. I almost had an arms attack tonight. What is the legal policy for this. Please help. Thank you

I have become ill over the last 6 months and I've had chest, sinus infection and eye infection in concession when I approached my general manager as it was concerning me he was defensive and said I could not see the air con report as i suspect there isn't one. He got me to leave thecwork.place and go home. I had handed in my motice i week prior because of how I was feeling and I gave i months notice. I had to callparamedics again at the weekend and discharged, tgey are sending me for immune test etcand sadly if I don't go into work I don't get paid as it's discretionary. He got me to leave the premises yesterdayand was extremely incensatice tomy asking question . I asked if Icould see the certificate of maintenance of the ACit he said I couldn't. I'm now off but dont know how I stand legally.

Hi, I work in an office with 8 other people, we have no ventilation system, no air conditioning and no open windows. in the office is a toilet and a kitchen. I have asked for an opening window or a ventilation system, I have been there 8 years but still nothing. During the summer the temperature in my office reached 32deg. i felt dizzy when i stood up, went home every day with a head ache, and could not concentrate on my work. I don't want to leave as I am due to retire in 18 months,

I injured my left arm - (I already have lymphoedema due to cancer) when stretching to open a window in a small room with printers and copiers giving off heat. I had to strecth over a printer that was sitting on the window sil. Also there was copy paper boxes in the way. I ended up pulling the muscles in my arm and shoulder. Since then a lump has appeared on my shoulder. I am awaiting scan results. I sometime loose sensation in my fingers since this and pain in my arm. Can I sue them as I am sure windows should have easy access...

Hi I work on the first floor of a building open to the public. Our heating / air con system is a weird air balancing system stopped working months ago.There are no opening windows. Our clients by nature of our business suffer with a variety of illnesses. The temperature on our office in November has been 28c. Many staff are constantly I'll with colds, sore throats etc for months on end. I myself have been unwell since early September. The hierarchy to get the fan on the roof replaced is proving long slow and resistant as will be expensive. Management think dehumidifiers will help and we have some desk fans, but ultimately the lack of fresh air is the big issue. What can we do / demand as it is getting ridiculous !!

I work in a call centre, we have windows and water but no fans or air con, with the weather we have had this week it has been more like 35-36C in our workplace, surely they is something to say they should provide fans or something to help us work better?

Hitman34 - 6-Jul-18 @ 11:49 AM
I work in a bingo and our air conditioning has not been working for approx 4 weeks..there is no ventilation no windows except in the managers office and no way to cool down as the temperatures have been extortionate in the premises esp the kitchen area.we are not permitted to use any fans and must wear full uniform at all times..what are our rights as employees..the manager told staff that it would be at least 10days for it to be repaired if it has been reported at all..

I work in a packing room within a warehouse, where we produce a "health" powder drink made from over 20 natural health foods, ie wheatgrass and barleygrass powder. we have no extractor fan and everywhere is covered (including staff) in green powder. one staff member is having serious breathing problems at present. our employer insists that an extractor fan is not needed as we have an industrial vacuum cleaner? what can we do ?

Jappers - Your Question:
I work in a care home. Recently had to down size and move office. Our working office is an old ironing room with no acess to day light, or a window. Size approx, 12'x 6'. Add a pc and a small medical fridge under stairs that are over the new office space. When told about the move which is in an accommodation block, with residents and wc in passage I advised that I need to have access to fresh air or forced ventilation. One can smell the wc at times and the heat and stuffiness is gross. Now the move is up and running. My colleague complained about the heat. The management added a fan. The new managers office and admin office on a separate block have had no expense spared on the ( refurb), but we have to put up with working in a hot smelly cupboard. What do you advice as management have not listened and failed to listen to advice given months ago.

Our Response:
If you’re a worker and you’ve tried solving a problem or concern informally by talking to your manager but you’re not satisfied, you can make a formal grievance complaint in writing, please see gov.uk link here.

does outside air supplied after being heated through the heating system qualify as ventilation
