Fire Extinguishers

Anonymous

Shaun,
British Standards information (including the standards themselves) is online at http://bsonline.techindex.co.uk/. You can search the site by keyword or by entering in the code for specific standards you are looking for, but you only get the barest details.
You may know that BSI members can buy British Standards at a significant discount. You don't need to be a BSI member to carry out a fuller search on their site, but you will need to register (which is free).
The standard you would appear to be looking for is BS 5306-1:1976 Fire extinguishing installations and equipment on premises - hydrant systems, hose reels and foam inlets, though this has been partially replaced. It costs £34 for BSI members, £68 for non members.

Could you please advise me how often a fire extinguisher should be checked by a competent person? The company that I deal with at present is stating that they should be checked every six months. I believe this to be an overkill and was looking at extending the time from 12 months to 18 months and maybe then to 24 months as there have been no problems identified at inspection. When an extinguisher has been discharged accidentally, it is replaced immediately and the used one brought back into service at the earliest opportunity. Many thanks.

British Standard BS5306 Part 3 2000, recommends that all portable fire extinguishers are subjected to an annual maintenance inspection and service, by a competenent person. It also recommends a monthly and six-monthly visual inspection that can be done locally on-site by a non-competent person. The qualification for compency in this instance is that the person (engineer) shall have attained a prescribed certificate of cempetency following a recognised training course run by an accredited British fire extinguisher training establishment, under a quality assurance critera. The certificate is awarded under the title of QAS 3169 part 3 and 4. On the annual service visit each extinguisher is stripped down and the contents empied into a bucket for re-use or disposal, depending upon condition. The exterior/interior of the extinguisher is checked for signs of corrosion and interior for signs of split/lifted linings, the CO2 cartridge is weighed and discharge hose and valve assembly checked for correctness of actions etc. The whole lot reassembled using new washers and seals where required, and the label signed off stating the date of that service visit.

This action varies slightly depending upon type but applies generally to all gas cartridge and stored pressure type extinguishers. However it does not apply to CO2 extinguishhers, which are sealed under high pressure. These are weighed accurately against their known full weight critera, which is stamped upon the neckband.



Once every five years each extinguisher (except CO2) is subjected to a discharge test, wherein the contents are expelled under the normal operating pressure and technique of the extinguisher, and then refilled as per a service visit.



When an extinguishjer has been discharged it has to be refilled or replaced as soon as possible, (bearing it mind that its purpose cannot be fulfilled while it is empty). Most larger type premises carry a small stock of spares so as to be able to replace the odd one or two during the year if necessary, thereby avoiding the costly call-out charge for an engineer to come on site to refill one extinguisher outside the normal annual service visit.

Note: You cannot use the part contents of any extinguisher once it has been parly discharged.

Is it illegal to tamper with or misuse a fire extinguisher(e.g. let a fire extinguisher off as a joke).

Anonymous

It is an offense to misuse an extinguisher under the Health & Safety at Work Act with criminal prosecution being a sanction.

Extinguishers must be serviced annually - 6 months is overzealous unless in an industrial environment of such a nature that the extinguishers are more prone to damage or deterioration

What are your views on the provision of fire extinguishers in company cars?

Tina,
In your explanation of the annual inspection required, you state that these do not apply to CO2 portable extinguishers.
What exactly applies to this type of extinguishers?
Also, do the CO2 extinguishers have to be fitted with pressure gauge or not?

Fire extinguishers in cars - tempting fate. Fire usually too much for small units to cope with - far more economic human wise to keep driver away from danger...hopefully if they are able.

Regarding British Standards Access, it should be possible to view these on line at a subscribing library, in Norfolk, all libraries now have internet access and a terminal can be booked and logged in by the staff so that you can see the entirety of a standard rather than just the precis which is enabled for non subscribers on line, priceless, as this lets you see if the content is releavent enough to purchase the standard rather than playing the lottery !

Does the 5 yr discharge apply to foam and powder? if so can this be done on site or do new extinguishers need to be purchased? Thanks

With regard to Co2 extinguishers; they are required to have a hydraulic test every 10 years, under the standards already mentioned.

i would like to buy a dry powder fire extinguisher and used in highly corrosive & humid location.
how can i choose the suitable fire extinguisher that withstand this environment

whilst this is partially correct, it does not apply to primary sealed portable appliances, they are only discharge tested on a 10 yearly basis too. Currently the only company to supply primary sealed cartridge extinguishers is Nu-Swift

the application and location of all portable appliance should ideally be located by a proffessional person. the best advice i could give would be to locate the correct fire extinguisher that is consummate to the risk, via the risk assessment process. in that way you will have the correct size and type of extinguisher,reccomended by a proffessionally compitent person.

As to the dry powder part of your comment.
while dry powder is designed to extinguish classes A B C and electrical fires. it also reduces visibility thus hindering escape, it can cause severe breathing difficulties when inhaled, and due to the content of ammonium phosphate, can burn the lungs and stomach if digested.

I am trying to find out if there is a legal minimum requirement for the number of fire extinguishers required for the number of people employed / present in a wokplace.

We seem to have an awful lot and this is obviously a good thing but I want to make sure that should any need replacing or be faulty we do not fall under the legal requirement.

the calculation as guided in BS 5306 is to take the area and x 0.065 therefore as an example 400 sq metres x 0.065 = 26 this is the minimum A rating required for this area, additional equipment is then added to make it consumnate to the risk ie Carbon doixide for electrical cover and a fire blanket in a kitchen for example.

if you employ 5 or more you must have by law have a fire risk assessment in place and the person who carries out the assessment should be able to tell you if you have to many and/or if they are located correctly.

the rire risk assessment is required under the regulatory reform ( fire safety ) order 2005

Hi just read all of the posts - I have a small business with 2/3 staff! - we have been shafted by a fire engineeer annually - discharging all (10) extinguishers each time he calls - please! - what is the legal situation - do I have to have the extinguishers checked each year -what if I dont?

The previous comments regarding premises area / extinguisher provision is technically correct, but slightly misleading. The "A" rating calculates out at "26" in respect of a 400 sq. metre area, however be clear that this does not mean 26 fire extinguishers!!

The "A" rating indicates the extinguishing power required to deal with a small carbonasceous (Type A) fire in its incipient stages. As a general rule of thumb, 1 water based extinguisher per 200 square metres is the norm and there should be a minimum of 2 units provided in any workplace, except where the floor area does not exceed 100 square metres.

Water based fire extinguishers, 9 litres capacity or a smaller size with additives, are rated at "13A". It therefore follows that in any workplace 2 of these units would be required, and additional units for every 200 square metres.

In respect of other types of fire, there are Foam, Carbon Dioxide and Powder type extinguishers available. These have "B" and "F" fire ratings. A fire risk assessment should identify where these other types are required.

In general, the provision of 1 x Water based and 1 CO2 type (2 Kilogram size) fire extinguishers are often the best combination to adequately form a fire fighting point within most workplaces containing no special risks.

Extinguisher points should be located adjacent to the exits from the workplace and no person should have to travel more than 30 metres in any direction to reach an extinguisher.

Maintenance is simple. Weekly visual checks by the users to identify any damage or tampering, and an annual test and examination by a qualified engineer.

Is the annual test a legal requirement if you only have 2 staff?

Mike Kane

Yes, it is a requirement for any workplace.

I agree with Mike the test is relevant to the equipment not people.

Just a thought for Bob Brown..........

If you have only 2 or 3 staff, why do you have so many fire extinguishers? Do you have a large premises?10 fire extinguishers seems to be a fairly large number and an annual discharge may not actually be required dependent upon the type of extinguisher installed. You might be being "shafted" to quote your post !

Good to see some sound advice getting out there.

We must remember that the 13A/200SQ M is for an empty building!

I found a warehouse, that was filled to the roof with spirits (not Ghosts!) and only had Water Fire Extinguishers. 6L AFFFoam units often give 21A (with some at 27A), also a B Fire Rating for flammable liquids (and liquefiable plastics). They also have a 35kv Test for use on Live Electrical Equipment. C02 Have a B Rating, but only knock down a fire, the gas floats away and the fire comes back. These now can have a 55B Rating (not 34B) in a 2kg unit, fitted with the new safety horns. Safer, Lighter and more effective.

After almost 36 years in Special Hazards Fire Protection and the last 25 years specializing in Portable Fire Extinguishers, I have never known any Fire Extinguisher in normal use that requires Test Discharge every year. You need to report these crooks to BAFT.
