Whilst (with good reason) the use of powder is frowned upon indoors in this situation,due to the use of accelerants and the resulting raging fire, the rapid knockdown and large mass for mass fire fighting capacity of powder is such it would be a worthy choice, but don't go lower than 1kg, ideally 2kg

Yes as less than 60 persons would be using it.

Sounds like a 'code hugger' quoting insurance requirements regardless of the real world, the sort that gives fire safety and H&S a bad name - from a risk assessment and life safety/legal compliance point of view it's not required.

The system is described here - as you see it's less combustible than wood: https://www.paroc.co.uk/knowhow/fire/fire-classification

A one room building with no relevant persons to protect most of the time, where the service penetration is to the outside and would safely vent in the event of fire? Unless there is an adjacent building or risk that would be affected by improper fire stopping in this case, which sounds extremely unlikely, then from a fire safety point of view you could fill it with chewing gum for all the difference it makes....

It's legal as long as it's managed such that all fastenings are removed when the premises are occupied. If this isn't happening it's an offence and management requires improvement or an alternative option considered

Strict interpretation of the signage rules is the use of an up arrow above the door as up is for straight on as well as up. When through the door you have another change of direction requiring another sign for the stairs (usually diagonal down & left, or down & right depending on how the stairs run)

Sounders have always needed to be in fire resistant cabling for a lot, lot longer than 20 years. This is a serious non conformance that affects life safety and must be remedied. Detection zones to call points and smoke/heat detectors have only required to be fire resistant since 2002 (although most good installers would use FP or Pyro anyway). This is because original conventional fire alarms would go into 'fire' when their cables were short circuited so a fire burning through cabling would still set the alarm off, which would continue to sound as the sounder circuits would be fire resistant. As long as the current panel is set to operate in 'short circuit = fire' mode (most modern panels default to 'short circuit = fault' mode and would need the setting changing) this is less of an issue unless the panel cannot be set for short circuit = fire So: Sounders in FR cabling - essential; detection zones in FR cabling - desirable

How often do we need to certify emergency lighting?
AnthonyB replied to a topic in Emergency Lighting
Size of premises has no bearing on applicability of legislation. Even a tent in a field if not used as a private dwelling is subject to fire safety legislation. If your fittings are genuine emergency lights (that will stay illuminated upon power failure using their internal batteries and can often be identified by their green LED light (which is illuminated under normal conditions to show the battery charger is on) then they require a suitable system of maintenance under the Fire Safety Order. The benchmark is in BS5266-1 where the fittings should be tested monthly for function (brief on/off test) and annual for duration (full 3 hours under battery). If the installation has been made by a competent person and in line with BS5266-1 then there will be secret key test switches that would allow you to carry out this testing. -
Flat fire door for private entrance
AnthonyB replied to Nibarb's topic in Fire Doors and Accessories
FD30s (smoke sealed). Why do you not have a smoke alarm. Unless it's a privately owner occupied flat that was built or converted before 1991 it should have one and if rented must. -
Boiler room fire door - is a door closer required?
AnthonyB replied to Tom Spearing's topic in Fire Doors and Accessories
If it's a cupboard you can fit it with a lock and sign it "fire door keep locked shut". No lock and you will need a self closer. -
Infrequently occupied cupboards designed to be kept locked shut don't have closers but rooms usually do, especially high risk rooms like laundries.
-
You can have a lot of glazing in doors and they still be fire doors, but you would have to specify this and get them from a suitable specialist provider. Off the shelf glazed doors from the usual retailers may be toughened for health & safety, but are very unlikely to be fire rated.
-
Unless that external door needs to be a fire door to protect an adjacent external escape route it doesn't need a self closer.

If you are in the common hallway and it's on fire (which it shouldn't be short of an aggressive arson attack using a lot of accelerant) you would evacuate, but if the block meets structural requirements it should be safe to stay put in your flat if needed.

This is a double post ,being asked in another section. I refer you to my answer there.

Check the fire risk assessment. Is this an exit at ground level to open air? Depending upon the location and distribution of the exits and any stairs and if the premises are stay put then there is a slight possibility the exit is for accommodation only and not required for escape - but I would want to see how they came to this decision.
-
If it's an internal fire exit from one internal area to another there is a good chance it's meant to be a fire door as well in which case it needs repairing/replacing and a new closer fitting. The final fire exit to open air doesn't usually need a closer as it's not a fire door unless protecting an adjacent external escape route.
-
The fact it's got it's own smoke control system suggests it is a non standard (not to Approved Document B) layout mitigated by a fire engineering approach. Layouts that are more open plan than the default approach of enclosed stairs and lobbies are not uncommon, usually using sprinklers and/or smoke control.
-
If correctly fitted and maintained they do have a reasonable amount of performance - they were intended to last up to 30 minutes even back in the day. Intumescent seals and cold smoke brushes are one of the main differences affecting performance, but in the right circumstances they remain acceptable (they aren't automatically and in many cases need upgrading or replacing). There's no evidence of there being any changes to require full retrospective application of standards, it would be too burdensome. Let's not forget that the fire doors that failed at Grenfell weren't the original notional doors, but the 'today' door sets that supposedly had all these regulations and codes to ensure their efficacy.
-
If there is no valid written agreement to have right of access they can do this with notice even if that messes up your fire safety compliance - this is why a well written deed of variation or easement is required as anything less can lead to your situation. If you can't prove title to the path and they can you are stuck. You need to consult a property lawyer - I have read of cases like this where if the (albeit informal) enjoyment of the access has been had for a prolonged amount of time the courts have enforced formalisation of the access right.

Yes, whilst the shop should carry out it's own FRA, which should include the risk to relevant persons in the vicinity of the shop (i.e. flats above), that doesn't mean you shouldn't include the existence of the shop in the flat FRA. It's clearly a 3 storey building of ground and two upper floors, for which you are assessing the upper flat floors common areas.

Sharing of costs for electricity supply for fire alarm system
AnthonyB replied to a topic in Fire Alarm Systems
Not uncommon and it doesn't exempt from provision if the system is required. If the conversion was to building regs it might not need detection. -
Local crews aren't often trained in fire safety beyond the basics, specialist departments in the FB do this. If it is a stay put block you don't need to know about a common area fire as the worst thing you can do is leave your home as several people have paid for with their lives. As these areas generally contain minimal combustibles you are safer in your 60 minute 'box' as it will eventually burn out or be extinguished. If it's a stay put block you don't need to know about a fire in another flat as that will be contained within it's own 60 minute box and whilst there may be some smoke leakage into the corridor that only means it's safer still to stay where you are. If it's full evacuate you need a proper fire alarm system with detection linked to a central control panel which covers the common areas and (as a minimum) the flat internal lobbies, with call points in the common areas and alarm sounders in the common areas and (as a minimum) the flat internal lobbies as the flats are not 60 minute boxes and you need to know about the fire before it breaks out into the common areas and to adjoining flats.

Depends on whether everyone would be stuck or there's an alternative, if being stuck or passing down the alternative would be a risk from the fire, if the alternative can take the number of people without bottle-necking or being too slow, if being stuck is a crush hazard as the area is too small etc. Many factors will influence if this is a trivial or major issue. The competent person responsible for the school's fire risk assessment should be consulted.
