I recently did a fire risk assessment and one of the action items was my recommendation for a new extinguisher at the exit from the office, and close to the front exit.
The only person likely to use this extinguisher is a female who runs the company from that office.
I recommended a 6kg water extinguisher because of its lighter weight being more suitable for a female, she told me not to be sexist and purchased the heavier 9 litre type.

Sounds like a bit of a bruiser to me. What next? Women playing football in their own world cup I suppose. Where will it end.

Perhaps you could have advised that size of an extinguisher because of her 'build' and not her sex? Would that be 'sizest'?
I used to work in the same warehouse as a woman who put most of the men to shame. She could lift a fully laden donkey if you asked her ( and that came from her!)
Or you could have said that the 6kg was 'suitable' for the risk.

Did you take the fire loading in that area into consideration when recommending the size of the extinguisher? Can you guarantee that she would be the only person that would use it, what happens if she moves to another office, or becomes pregnant or gets an assistant. If she is lone working would you expect her to be fighting a fire? etc...
I guess it is important to consider the people using the equipment and their training, but I would also be considering the hazards present, nature of the activities and the features of the building when recommending the means of fighting fires.
On another note - its not sexists to suggest a lighter extinguisher that a female could use (I would personally never do this myself as you can never guarantee that only females would use them) . Its a fact that the average female cannot lift the same weight as an average male.

The lady in question is very trim and works in an otherwise men only environment, an engineering company with workshop where they hot cut and weld.
The reason for the water extinguisher is 1. There weren't any at the front of the unit and 2. Nearest extinguishers are inside the workshop and mainly CO2 and DP.
I didn't want her taking a risk in carrying a heavy extinguisher from the workshop into the office to have a go at a small fire.
Chances are she would evacuate the building without looking back, after sounding the alarm.

Why are you supplying water extinguishers?
Slowly but surely we are removing ours and replacing them with AFFF which can be used on Class A+B fires and also have a conductivity rating of 35KV which means they can be safely used on live electrical office equipment (safety distance of 1 metre required).

Adrian Don't AFFF make a mess and two why water if there are electrical items anyway.

A word of caution here - not all AFFF can be used on live electrical equipment as described in the previous post, especially the old ones with a jet dispense and not a spray.
But yes - I would always prefer a foam type extinguisher over just a water one, the mess from the foaming agent is negligible in a fire situation me thinks.

What has the fire loading got to do with the weight of an extinguisher? Many (most) 6 litre water extinguishers have a 13A rating so will deal with exactly the same size fire as a conventional 9 litre.

You are correct - some manufactures 6 and 9 ltr extinguishers have the same fire ratings and your point is valid for the OP's question.
However, fire rating for extinguishers are categorised (e.g. 5 - 8 - 13 - 21 - 27A etc... (0.5M sticks of wood in each transverse section)) its possible that the 6tr just makes the 13A category but the 9ltr one doesn't quite make the 21A category so it is labelled as 13A, no doubt the extra 3 litres of water in the 9ltr extinguishers will perform better that the 6ltr albeit they have the same rating.
Note: Fire extinguisher ratings are not an exact science, for example, they are only tested on one combustible material (wood) amongst many other things.
When recommending the means of fighting fires in a building, or reviewing a FRA I will take many factors into consideration including the fire ratings of extinguishers, AND the fire loading of the building in which I think is crucial. Outside our file archive room (which is full of card and paper) their is a 9ltr 21A water extinguisher, which was changed from a 6ltr 13A extinguisher due to the fire loading of the archive room.
No offence intended here just trying to justify my posting in which I accept that it may have strayed from the OP.

All interesting comments, I made the recommendation mainly from a point of there wasn't an extinguisher at the front section of the unit, a fire extinguisher company had recommended and provided all others but missed the front, where the risk changes fom an engineering workshop to an office.
In the workshop there are many DP and CO2, great for the risk but no good if the lady needed an extinguisher for a small fire in the office.
I considerd the most likely user, the lady, and the small risk of fire as the office was kept very neat and tidy with no waste paper lying around and all electrical appliances in good condition and tested. Final exit a very short distance of travel.
The lady knows better than to attack a fire anyway, more likely she will sound the alarm and get out, and call the FRS out.
Nearest fire station within one mile but we all know that means nothing these days.

Morning All,
Valid points (Invictus & Toe) - My question is.
1. Why have you chosen a water extinguisher as per the” fire extinguisher company recommendation”? 2. What are the chances of a wood, paper fire compared to an electrical fire in the office? 3. What is the probability that if there is a fire in the workshop “someone” will utilise the water fire extinguisher form the office. ( it is not every day that we are faced with a fire, the human element fact takes over and a fire extinguisher is a fire extinguisher no matter what the colour code is)

MD9Z1 you are being very critical here, but you need to read my posts before you write again.
It was I who chose the water extinguisher and not following any recommendation.
I am the fire risk assessor and it is entirely my decision based on what I saw at the time of the assessment.
If I followed your logic about chances of types of fire we would have one of every type of extinguisher in the office.
My initial post was in good faith and I do not like to be criticised by anyone especially as the thread was meant light hearted in the first place.
Rant over, thank you and good night ha ha.

FireSafety101,
Please don't take this as a criticism as that's not how it's meant, it's a genuine question which has bugged me for a while;
Why would somebody choose to put a water extinguisher in an office given that an office fire (in this day and age where smoking is banned) would almost certainly be caused via an electrical appliance?
We recently looked around a few offices (planning on moving) and most, if not all, still had water extinguishers so this appears to be quite a common thing.
I'm not a fire expert (I'm more a "jack of all trades" H&S guy) but i know enough to know that water and electricity don't mix well. Would an appropriately sized CO2 not be a better choice in an office environment?
Again, not a dig mate, just curious as to why you chose water?

In response to Stern's comments, there may well be fires that occur in an office that are more suited to being extinguished by water. I am aware of one instance, from a reliable source, where no electricity was involved and where the power of the sun alone almost ignited paper on a desk. A glass paperweight was positioned on a desk and it focused the light from the sun through an open window to a point where the paper underneath started to smoke/smoulder. We believe the desk and its contents could have ignited fully had the person not been sitting at their desk, noticed the plume of smoke and moved the paperweight. Water extinguishers still have their place in the fire fighting armoury.

Hi Chas, I read a similar story in the paper recently where a house fire was caused from the sun reflecting off a mirror so i accept that its a possible source of ignition. However i think it's safe to say that this is very rare. In fact, it isn't even mentioned in the official stats I've available at www.gov.uk (i assume it would come under the "other" category. What the stats do show is the following statistics for causes of fires in "non-dwellings" in 2013/14: -Total fires: 14,900 -Electrical Distribution: 2,900 -Electrical appliances: 2,700 -Cooking appliances: 2,600 (doesn't state what but would assume some electrical in there). Out of the remaining 6,700 fires, most of the categories are things which would not normally be present in offices such as smoking (900), matches (200), welding equipment (400) etc so if you actually filter it down to "office specific" sources of ignition, electricity is by far the most common. -Common sense tells us that the most likely source of ignition in an office is electrical -Official stats also tell us that the most likely source of ignition in an office is electrical -Water can't be used on electrical fires -So why do people put water extinguishers in offices?

I think Stern is absolutely correct, but like him I'd be very happy to be persuaded to the contrary.
Any fire in an office can be extinguished with a carbon dioxide extinguisher, and if this is the only one there’s zero chance of confusing and the hazardous effects of putting water on a fire in piece of electrical equipment.

If you read my initial post you will see my recommendation is for a water extinguisher at the exit from the office and close to the front exit.
The reason for water is the area immediately outside the office is a lobby with four doors, as follows: 1. Ladies toilet, with paper towels and loo rolls and some items of clothing, 2. Entrance to engineering workshop with many CO2 and powder extinguishers, 3. Entrance to office, a small room with timber and vinyl furniture waste paper bins, plastic/electrical appliances, all recently tested so very slight fire risk, carpet, items of clothing, etc. etc. 4. Exit out to street.
My verbal recommendation was for the extinguisher to be sited in the lobby so available for use on the way out and to cover most of the hazards I considered at the time.
I could of course have recommended CO2 as well but decided not to as there are many of those inside the workshop and just on the "other side of the door".
Water can be used for electrical appliance fires, having first isolated the electric supply, that is just a point I mention, not one I recommend.
I hope this answers the question as to why water.

Taking what you've said into account, I still wouldn't select water. Yes it's my opinion but it's an opinion based on the simple fact that the main source of ignition in an office is electricity and you can't use a water extinguisher on electricity.
Towels, paper, clothing, waste paper bins... it's all fuel. What I'm talking about is sources of ignition, ie what could cause this fuel to ignite in the first place and in the vast majority of offices it's going to be electrical so still don't see why we still see water extinguishers being specified and supplied to offices by "experts".
In the event that the extinguisher in your example needed to be used, the person in the office would need to isolate the electrical supply (as stats prove its most likely going to be electrically caused) or go into another room and pickup an CO2 or just spray and hope.
That's way too many variables and opportunities for mistakes for my liking. I really don't see why you wouldn't just play it safe and specific a CO2? Am I missing something? Again, not a dig, I'm just genuinely interested as I see this sort of thing a lot.

Flippin' 'eck 'essy not you as well !!!!!!!!
To add to your tirade men on building sites now carry lighter packs of cement, sand etc. undertake manual handling assessments and complain when they are asked to carry anything "too heavy" they use trucks to move around materials, as do store staff in supermarkets etc. etc. etc.
Workers at height use MEWPs instead of scaffold, ladders are left in/on the van, mobile canteens are on hire to enable all workers a nice break from work, some with showers and drying rooms for wet clothing.
Yes I know we have moved on into the 21st century where everyone is equal but equality has worked both ways.
As it happens I know the lady in question very well and there was no way any offence was to be taken.

Perhaps I'm misinterpreting your closing threat at #25 by asking you to think again if you are serious about ceasing to be an active user of this forum, i.e. someone who starts threads or posts responses unlike passive users who simply read threads and either rarely or never contribute. Some of us enjoy your postings as part of the 'rich tapestry' of content on this forum!
One snag with this forum is that users can interpret postings in various ways. I guess that some of us were correct in interpreting your original post as little more than a humorous anecdote about someone's reaction to advice you gave during work. Therefore, on a general note for you and other active users, it's advisable to use exclamation marks, smileys, frownies and/or choose wording which may help to reduce the risk of humorous content being misinterpreted as serious.
Also, it seems that some or many IOSH members are not aware that the Members Forum on this website was split into three last year and now includes a Social Forum intended for light-hearted topics and banter. Also, in general, the active users of the Social Forum tend to be more courteous to others in their postings than some people on this (public) discussion forum. Therefore, for IOSH members who haven't logged on for a while, why not do so and have a look to see what you are missing on the Member Forums? Apologies to non-IOSH members who use this forum but obviously won't have access to the Member Forums. Some things in life are exclusive and that includes access to the IOSH Member Forums!!
p.s. To avoid misinterpretation, I had better add that my definition of passive users above was intended as neutral rather than derogatory. There are a number of valid reasons why some users never post on this forum or rarely do so.

I was not aware of the Social Forum and will have a peek.
Thanks again.

In support of Firesafety101, CO2 are good in offices but mostly for surface fires and are not rated for class A- combustible solids. Take a sofa or seat for example, smoldering deep into the cushions would not be extinguished by CO2. CO2 does not remove the heat element from a fire. Water extinguishers with additives can be bought where they have a conductivity rating of 35Kv so would be perfectly acceptible in this scenario. Kevin

Most places I have worked have had water extinguishers at the doors to give you a chance to get out, the comment about some women not liking the noise- I agree, the women I did my fire training with were a bit taken back by it. By the sounds of it the idea is to get out, not to fight something out of your control- which is sensible in my eyes. At the end of the day fs101 has done his assessment and it is based on his site which none of us know enough about to make comment on.

In my experience, if you use a C02 on a paper fire in an office environment you are likely to blow burning paper and embers all over the place resulting in potential fire spread. Water or foam for carbonaceous! Decent fire awareness training should point out the difference between classes of fire and the type of extinguishers to be used on them but of course then you still have to rely on someone making a conscious decision in an emergency situation. I can't see an issue with a water extinguisher if it is accompanied by a C02. Our ladies didn't bat an eyelid by the way.

Is this one still running ha ha.
Thanks for the support everyone and the comments from you all.
I think this shows there is a vast gulf in our fire safety awareness and knowledge.
I re-visited the premises yesterday to check up on their action items, they had a two A4 pages list from me. All done to my satisfaction and they will now send the report off to CHAS with their application.
If they had not applied to CHAS they would still be without a fire risk assessment, and water extinguisher on the MoE at the front, and this thread would not have existed.
What a great shame that would have been eh.
Have a good weekend everyone, school hoildays now whoopee.
