As a Nursing Home and their fire alarm engineer got convicted for an alarm with a defective fault buzzer and deliberately causing that defect respectively (plus a few other things) I would say that yes, it's critical! You can service it but the service report would obviously need to highlight the defect and no certificate issued. If you don't service it someone else will!

Annex I I.7 (e) would seem appropriate (annual) - they operate similarly to mid duct shutters

Emergency lights- monthly function (as you do) and annual 3 hour duration (which you could do too). Reference BS5266-1 Assuming from your description you have Grade D1 or D2 residential smoke alarms then the service regime is only a monthly test using the test buttons on the alarms - unless you are sheltered housing or a similar scheme with detection linked to the telecare/warden system there is no requirement for external servicing (principally as there is little they could do that you aren't each month) Reference BS5839-6:2019 If you are a purpose built block of flats and the commo

Answered duplicate question.

Many buildings have only one entry/exit and are perfectly legal. The size and maximum permissible numbers that form a typical Portacabin are such one exit is more than adequate. Is it an open framed generator or an enclosed cabinet one?

As people won't naturally starburst to each exit equally there's a chance you will have an excess number using a door with a strong risk of crush and the door being blocked - the Station Nightclub in 2003 was an example - there were multiple exits but people went for the familiar ones, which opened inwards and so one of the leaves got shut under pressure and the other got blocked with bodies. Also the doors cannot have panic fastenings if inward opening. Options are: - Re hanging doors - Having Stewards at each door to be able to bolt them open in an evacuation - Do nothi

You've sort of answered your own question! If the zone plan is a decent one with the actual layout rather than just a shaded outline it still has value, otherwise it ticks the BS box with little benefit.

Hardly mitigating the effects of fire as required by the legislation although it could secure escape. If you are unfortunate to have a fire that isn't controlled, the damage and disruption bill and investigation by the loss adjuster as to why it wasn't put out will no doubt see you do have them next time!

Due to the quantity stored it appears to need to be treated as a dedicated store (otherwise the storage amount permitted would be less) so shouldn't have anything else - are you sure it's six hundred and thirty litres as it would have to be a pretty big cupboard?

If it's an high risk then it's recommended for indemnity purposes to tell the client as once, both verbally and in writing (we have debrief forms for that purpose) rather than leave it until the report. Imminent risk to life is a moral choice rather than a legal obligation - do you tell the client and leave it or, if you believe they aren't actually going to act escalate it? The public interest test and whistle-blower's legislation would indemnify the data breach, but you would (if they found out) loose a client. It's a judgement call really - there is no single answer.

There hasn't been a 6 monthly emergency lighting test for 16 years other than a means to make more money by out of date or unscrupulous contractors, the monthly test has been around for decades as has the annual EL test. Depending on the type of detectors and their purpose the service interval could be 6 monthly, annual or nothing at all !

Despite them being perfectly legal at the time of install I know recently some local authorities have wanted them removed, certainly if nothing else they are a burden on the service charge.

If you were going to ban any it would be the battery only ones, where there have been multiple deaths over the years due to flat or missing batteries - this is why the law has, for many years, required the mains ones in new or refurbished premises. If you don't know what you are doing, get an electrician to fit them.

As long as the code isn't required in the direction of escape there would be no automatic issue with doing that.

The biggest issue with no common electricity supply is where the tenants are all on prepayment meters as there is the risk of an extended period of power loss to the system where a resident cannot afford power. However the answer to that is to provide extended back up power supplies beyond the 72 hours normally provided. As you aren't prepayment there isn't this issue and whilst using a landlord supply is preferred it's not a legal requirement and a tenant feed could be used as long as they are recompensed for the usage. As for spurring off your feed that's one for an electrician to

Simple answer - it doesn't! If you immersed the plastic extinguisher in reverse osmosis filtered water, especially warm water, and left it there in the water then gradually tiny amounts of plastic would 'leach' into the water (why you are only meant to use most plastic bottles once) but this has nothing to do with a plastic extinguisher in service.

Sounds like it's a CLASP building for which there are limited practical improvements that can be made to the passive FP issues as they are endemic to the means of construction (they were meant to be temporary and all demolished after 10-15 years). The usual approach is L1 fire alarm, get everyone out and sacrifice the building. The various editions of BB7, the predecessor of BB100, may deal with this, I would have to check my copies in the office. There are some sector guides dealing with what you can do to improve CLASP buildings fire protection, it would be worth casting your eyes

If all the distribution boards and meters are new and compliant with current wiring regulations they should all be made of non combustible housing material and not need further protection. If not then they would need the required fire resistant enclosure, which could be a traditional plasterboard and stud enclosure or a purpose made electrical board enclosure https://envirograf.com/product/electrical-consumer-unit-and-distribution-board-fire-protection-system/

Why is the door being added? If it's a cross corridor door in a corridor with escape in two directions to split the corridor to protect the escape route (required for corridors over 30m under old guidance, 12m in modern guidance) then effectively it needs to be a FD30S door. (In the old days it could be a lower specification fire check door with smoke seals as the main purpose was to protect the corridor from smoke, but now proper spec doors are required) The wall/partition around the door also need to be to 30 mins as well - any ceiling void also needs firestopping/partitioning above the

The green lights are tiny little LEDs in the emergency light fittings indicating a mains supply is entering the unit's battery charger. They are brighter than the red LEDs that used to be used for the same purpose in the past, but it's an integral part of the fitting and not optional. The external lights are 'maintained' emergency light units (i.e. always lit even if the mains supply is working) and I would assume that they have been installed to ensure the stair is lit for use in an emergency without having to mess around looking for a light switch. Minimum light levels are given in B

The outer container is just an alkaline solution of water, sodium bicarbonate and a foaming agent/stabiliser such as saponin, liquorice or turkey red oil. Whilst you shouldn't drink it it's not really that dangerous. The inner container is a water based solution of aluminium sulphate which is mildly toxic and can cause severe eye damage (and damage to metal surfaces) but isn't really deadly. Whilst the chemicals will have degraded over time, they will still react, producing foam under pressure and the cylinder is likely to be in poor condition so just to be safe do not empty it by se

Powder can be used indoors, it's a fallacy that the British Standard bans it, just that a consideration of the effects on discharge should be made in a H&S risk assessment. The medium to large fires thing is a fallacy as portable extinguishers are made (& have been for over 50 years) specifically for smaller fires. Some of the substances you mention fall into the Moderate category for foam destroying action but none are severe. They will destroy a foam blanket, particularly the thin film formed by the non aspirated spray of current extinguishers. Even AR foams have a vas

Sounds like its been connected to a switchable live and not a permanent live. Some domestic lighting circuits are wired so there is only a switchable live from the on/off switch to the light fitting.

Can you sketch the layout? Is the floor all in the same occupancy? How long is the corridor? Are smoke detectors in every room as well as the corridor? It may be OK, but there are several factors to consider first.
