FQA - Fire Questions Answered

Fire Doors

I have a question regarding the fitting of smoke seals to a double set of fire resisting doors. I have inspected a building which has a set of double of FD30S protecting a stairway between first and second floor.

Both door leafs have “pyroglaze”, heat and smoke seals around the top and edges. One leaf only has a heat seal but no smoke seals on the meeting edge; the other leaf has neither smoke or heat seal on its meeting edge.

I am aware that I will have to ask for a heat seal on the missing meeting edge (no certificate with doors) But do both meeting edges have to be provided with smoke seals?

I have looked at various guidance notes and cannot seem to find a definitive answer, Dorset Fire and Rescue Guidance seem to advise fitting them to one meeting edge only.

Weights of doors - I am the moving and handling coordinator in a hospital Trust and at the moment I have been asked to investigate injuries that may be occurring due to problems with the weights of the theatre doors and types of closures on the doors. What I am interested in is guidelines for recommended weights of doors, the kind of closures that can be used in areas such as operating theatres. It would also be useful to know if this has been raised as an issue previously in other NHS Trusts.

Common areas of blocks of flats - I have a client who manages a block of flats, some of the flats are owner occupied and some have tenants in. The question I have is who is responsible for ensuring that the flat entrance doors are maintained and are up to the required standard? This block has various flat entrance doors that are not compliant and require upgrading/replacing. The thing is that the management company are hitting a brick wall when it comes to insisting that these doors are brought up to the required standard, the flat owners are ignoring them. Where does their responsibility start and finish?

Glazed panels - Please let me know whether it is possible or legal to retrofit a glazing panel into a 2 hour resisting steel pedestrian fire door.

Door seals - We install Fire Doors which require a 1 hour rating, we would like some options of the products that we could use to seal the door frames.

Any ideas on what we could use to achieve a 1 hour fire rating around doors that is more cost effective than the following:

We currently use Fischer Fire Barrier Foam 42755 (600009) and then a Nullifire N701 sealant to achieve a 1 hour fire rating when fixing doors.

We also used in the past Fischer Fire Stop Foam 42757 (60018) Fischer Fire Stop Foam which did not require the sealant.

Ideally we would like a 1 part foam that is more cost effective cheaper than the Fischer product, any ideas?

Link to bells /sounders - Can you point me in the right direction for some advice on the BS to do with Automatic Doors, we have been told that they should not be linked to Bells/Sounders and this is stated in BS5839, but we can't find it? Would you know someone who can guide us? There is a BS7273-4: 2007 (for the Operation of Fire Protection Measures. Activation of Release Mechanisms for Doors), any idea how much this would be through yourselves?

Houses in Multiple Occupation (HMOs) - I have been informed that fire doors in HMO now have to be installed to residents flats from the common areas is this a new regulation and is this regressive or is it to be done if residents change their doors in future?

Requirement for fire doors - Are specific fire doors not mandatory unless the building comes under the Building Regulations?

If Building Regulations approval is not required for a workplace small modification build where a small testing laboratory has been created within an existing office space, would I be correct in saying that specific fire doors are not required between laboratory and remaining office space unless assessed as necessary from a fire risk assessment?

Fire doors in block of flats - I am the secretary of a Residents Association of a block of flats. The block was built in 1929 and contains 33 flats.

We have been notified by the freeholders that under current legislation it is now necessary to install pairs of fire doors in all of the five common corridors. Currently we have smoke detectors installed, an external fire escape, and fire extinguishers. The freeholders have produced a Fire Assessment which details improvements to be made including fire doors.

However it has been suggested by one of the tenants that in such a block it is not necessarily a statutory legal requirement to fit such doors in the common corridors and that for each individual flat to have a fire resistant door would meet the legal obligation.

Could you please inform me as soon as possible of our Legal requirement or alternatively suggest whom I can contact to seek the relevant advice and opinion.

Do all my exit doors have to open in the direction of escape?

I live in a block of flats built in the 1960s. I think the doors are fire doors but don't know how to determine whether they are up to today's standards. Can you please advise how I can do this please? We have had a number of quotes from companies offering to fit slow closures, hinges and smoke strips but they are unable to confirm whether the doors are up to standard or not.

Is it safe to fit a door closer to the front door of a flat or apartment when there is no fire alarm and detection system fitted to the property i.e. the door could close behind you and you could be trapped in a common area that was on fire or had filled with smoke from the floor below?

The existing steel door to our commercial boiler room has rusted in the open position - this was on a sliding steel track and we now need to fit a fire rated door within the brick opening with a self closing mechanism. What period of fire resistance is required to a boiler room door?

We have recently had georgian wired glazing and new fire doors fitted into a screen at our church with the intention of providing 30 minutes fire resistance. The installer has used an intumescent mastic (unknown type) to seat the glazing and then mastic between the glass and the beading. He has then pinned the beading into the hardwood frame. I thought that the intumescent would expand and force the beading off leaving the glazing liable to fall out. Am I right in my thinking?

Do we need to paint any of the frame with intumescent paint or varnish to stop the beading burning away?

I have tried to locate a definitive leaflet about the installation of this glass but could not find one - can you help?

What is the recommended maximum gap around the edge of fire doors, with or without smoke seals?
