If you are only having 10 people then you would not usually require a secondary exit route. If you did require a secondary route for some reason it would require a fixed stair

If it's a final exit to open air and is not close to an external escape stair (that could be affected by fire if the door was left open) then from a purely fire safety point of view the door can be open

Have you tried to obtain the fire strategies for the blocks? Doesn't sound like Approved Document B was followed for the builds so the rationale used needs to be understood, perhaps single stage evacuation for the whole premises was used (it's rare a new bulid resi has full evacuation but it's not unprecedented). If it wasn't mixed use or was mixed use to strict rules of ADB I'd be removing the resi call points and sounders and leaving the detection for the operation of the smoke control systems.

It should only last roughly 5 seconds. If it's lasting longer then the site needs to train it's staff to use the walk test function on the system (which automatically silences the alarm sounders after a few seconds) or if the panel is too basic to support this it needs to use two people for testing.

This should have already been specified as part of the building control process. If the works comply with Building Regulations Approved Document B for new flats there would be no need for a communal fire alarm system, just Bs5839-6 Grade D LD3 smoke alarms to each flat. As there should be smoke vents to the common areas these would need smoke detectors, but you don't need alarm sounders or call points. If you are not following Approved Document B then you will need a more comprehensive system but without the exact detail I can't be specific.

You'd be mad to stop them installing something that could save your life (although are they going to bill you if you do let them?) but technically you can (subject to your lease of course which may give the freeholder rights to do this) - you need to know why they want to put them in from their FRA (there is a very slim chance the alarms are for the benefit of the whole property not just your flat in which case you could be forced to comply, but this is very rare) .

If only one exit, regardless of width, then you are restricted to 60 persons. This is your guidance https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/422195/9294_Small_Mediumt_v2.pdf "At least two exits should be provided if a room/area is to be occupied by more than 60 persons."

https://www.gov.uk/workplace-fire-safety-your-responsibilities/fire-risk-assessments Fire risk assessments As the responsible person you must carry out and regularly review a fire risk assessment of the premises. This will identify what you need to do to prevent fire and keep people safe. You must keep a written record of your fire risk assessment if your business has 5 or more people. Carrying out the assessment Identify the fire hazards. Identify people at risk. Evaluate, remove or reduce the risks. Record your findings, prepare an emergency plan and provide training. Review and update the fire risk assessment regularly. The fire safety risk assessment chart gives more detailed information about these steps. You’ll need to consider: emergency routes and exits fire detection and warning systems fire fighting equipment the removal or safe storage of dangerous substances an emergency fire evacuation plan the needs of vulnerable people, for example the elderly, young children or those with disabilities providing information to employees and other people on the premises staff fire safety training Help with the assessment You can do the fire risk assessment yourself with the help of standard fire safety risk assessment guides. If you don’t have the expertise or time to do the fire risk assessment yourself you need to appoint a ‘competent person’ to help, for example a professional risk assessor. Your local fire and rescue authority might be able to give you advice if you’re not sure your risk assessment’s been carried out properly. However, they can’t carry out risk assessments for you. Assessment guides You can download the following guides on risk assessments in: offices and shops factories and warehouses sleeping accommodation residential care premises educational premises small and medium places of assembly (holding 300 people or less) large places of assembly (holding more than 300 people) theatres, cinemas and similar premises open air events and venues healthcare premises animal premises and stables transport premises and facilities You can also find guidance on: risk assessments if you work in construction purpose-built blocks of flats and other types of housing if you’re a landlord

First you need a refresher course, then liability & efficacy insurance, a full set of tools, consumables, service labels, etc, initial stock and an account with as trade supplier (expect to pay up front at first unless you've got decent credit references). Some contracts will require you to be third party certified, most won't. Membership of one of the trade associations can be of help. I'd do some course to up-skill to offer other fire safety services as well, if you aren't going to be one of the many cowboys you will struggle to make a lot of money just doing extinguishers these days.

Very dangerous for whoever did that to leave the extinguishers installed without the pressure charges as whilst obsolete somebody may see them and assume they may work - in 1982 they were still serviceable so it's likely they've been stripped in more recent years. Still collectable if in good order as the charges are still in circulation to restore them.

As you will need to go through Building Control to carry out these works legitimately your BCO or AI will advise. It may be possible to have a single exit based on travel distance, but without seeing the plans I cannot say for sure.

They need to carry out a fire risk assessment in order to comply with the Fire Safety Order. If you get a competent person to do it they will be able to advise. It's not just about numbers of persons, but travel distances and the provision of the external stair in the first place may well have been due to this. Travel distances, fire alarm systems, fire compartmentation & protection of escape routes, stair and door widths, etc are all relevant factors - if you have a suitable and sufficient FRA it will all be considered.

Electromagnetic locks should release on power failure (but many have back up power supplies to prevent this), via a fire alarm interface and by a green 'break glass' override (looks like a green version of a fire alarm call point, but is a double pole isolator to drop the power to the magnet). BS7273-4 is the relevant British Standard.

The Model E4000 contauins a Nu Swift exclusive extinguishing agent - Uni-Flash liquid and is 75% 1-1-1 Trichloroethane and 25% Bromomethane. It was developed as a cheaper alternative to Chlorobromoethane (CBM) which was the post World War 2 alternative to the commonly used Carbon Tetrachloride (CTC). CBM was less toxic and more effective than CTC, but far more expensive so many customers stuck to CTC - Uni flash liquid was intended to be an option that was less toxic & more effective than CTC without being too expensive. Uni Flash liquid was soon overtaken in the late 60's by the invention of BCF/Halon 1211 which replaced all existing vapourising liquids being far superior in effectiveness and low toxicity, although Nu Swift continued to offer it for many years after until the early 80's. It's main use was for electrical fires, machinery/vehicle fires and small liquid fires. The contents are toxic and teratogenic in their own right and the by products of discharge on a fire are also toxic. The contents are also destructive to the environment and in 2003 general use of these and other halons became an offence as a ban was introduced. Nu Swift were infamous for their silver tongued salesmen who would say all sorts of things to justify their prices and to get a sale and 50 years life is one example (Nu Swift service engineers themselves would have condemned them at 10 years old!) These extinguishers should have been annually serviced and every 10 years discharge tested and recharged and should have be taken out of service many years ago. Where is the farm? If anywhere within my area of work I'd replace them free as I would put them in my fire extinguisher museum.

Fire escape routes are generally required to be 'protected routes' so that they cannot be affected by fire and smoke until well after sufficient time has elapsed for everyone to escape. There are two principles to the protection - that of protection from the effects of fire adjoining the route, dealt with by the use of fire resisting construction and doors to the route; and that of protection from a fire originating in the route itself, dealt with by the route being 'sterile' and containing no ignition sources beyond simple electrical fittings and no combustibles beyond wall and floor linings (which themselves usually should be low or non flammable). Drying machines are a known fire risk and have over the years been involved in many fires, including injury and fatality fires, in domestic and commercial premises and so would understandably be unacceptable on an escape route. Whilst detection is fitted the heat output and smoke that would be in the escape route by the time it activates could well be such that the route is untenable or at least presents a significant risk of injury trying to pass it.

If it's a fire escape window I would remove the restrictor now as otherwise you won't be getting out in a hurry!

Contact your local Council Planning Department as there will be requirements with Planning Permission and Building Regulations. https://www.planningportal.co.uk/

No, only where a repair or alteration is required.

They should all be fire doors including the other flats. The Management Company should be enforcing this to everyone, not just you.

It's not more cost effective for the customer to scrap CO2 at 10 years - there is is still an appreciable price saving on exchanging for an overhauled unit. Suppliers like replacing new as they get the margins on a new sale and unlike other types of extinguisher which they have to pay to legally dispose of they actually can get credit back on old CO2 extinguishers. CO2 extinguishers do not require a 5 year Extended Service and only require annual Basic Services until the 10th year at which point it requires an Overhaul and should be service exchanged. The chances of it being actually an Obsolete Model are extremely remote if it's as recent as you say, unless they are saying it because it's steel bodied, which is completely untrue as well..... If you send me a photo of the extinguisher in question I can give definitive advice: anthony.buck@alcumusgroup.com

If your flats are purpose built the current guidance is actually the LGA Guide Fire safety in purpose-built flats: http://www.local.gov.uk/sites/default/files/documents/fire-safety-purpose-built-04b.pdf The sleeping risk guide remains relevant for hotels, boarding houses, etc. First thing you can do is dispense with the communal domestic single station smoke alarms which serve no real purpose and are non compliant anyway.

It's a requirement if your fire risk assessment deems it necessary.....

Lift control fire alarm interfaces are required in the BS EN for lifts, but it's never been a specific requirement in most fire safety guidance, just a very useful extra.

A competent fire risk assessor should be able to specify extinguisher requirements in detail - it's the FRA after all that determines what provision is required. All to often when the extinguisher engineer, whose living is based on supplying extinguishers, is asked a premises often ends up with excessive numbers and inappropriate types, which we then have to get changed and removed. If deciding to use a third party risk assessment provider and they can't specify your requirements related to extinguishers, fire alarm systems, etc then walk away - they shouldn't be doing the job. If the RP is trying to do the FRA in house then there is basic guidance in the Government FRA guides, but for complex risks you either can either use an FRA consultancy for an independent survey or through yourself on the mercy of the extinguisher engineers (who do 'free' surveys, but then claw it back in extinguisher & sign sales)
