Morning all,
BS5266
5.2.8.5 Toilet facilities and changing rooms
Facilities for use by disabled people, and/or any multiple closet facilities without
borrowed light, should have emergency illumination from at least one
luminaire.

(changing rooms)Could it be argued that a bedroom (residential care)is the area used for changing, and should be provided with a form of em lighting.

Your thoughts?

I have just seen an office block that is in the process of being renovated to residential flats.
The flats are within lobbied corridors, with maximum travel distance to the stairway of approx 11m. The corridor is subdivided with a fire door, so that there is a maxium of about 7.5m to the first door (and all the flats are within this part) and then an additional small corridor (approx 3.5m) leading to the (single) stairway. The AOV (natural smoke shaft) is located within this second corridor.
The question is, does it make sense to have the smoke shaft in the second-half of the corridor - so there is no smoke control in the residential part of the corridor, and will only vent smoke if the mid-corridor door is open?
Would it make more sense to remove the mid-corridor door so that the smoke has means of dispersing - but would mean that the travel distance now is 11m to a protected escape route?

Thanks

Suppers, the voice of wisdom as always. You still around then?

Still a regular visitor.

Brian, I know your school was good because it was approved, but did they really teach you latin? Your speliing is as perfect as all your previous work for your previous employer if I may be so bold as to say so.

It's very difficult as there is no standard identification method - whilst several manufacturer's use pink dye, some use green or blue and I've found some that are yellow just like non FR foams.

Whilst not infallible from the different manufacturer evidence I've seen over the years if it's aerosol can type expanding foam then generally if it's being used for anything other than very small linear gaps (not penetrations to said gaps) and narrow gaps to door frames (often capped to 10mm with mastic) then there's a very good chance it is an incorrect use that will fail spectacularly early (as graphically illustrated in the ASFP video).

Gun applied cartridge single & 2 pack non aerosol 'foams' such as specialist products from Hilti, Mulcol and others generally have a much wider scope of use including service penetrations and much larger holes and visually look quite different.
