Fire stopping/compartmentation in service risers.

[Guest Jack Atkinson]

Hi,

I’m hoping someone can help. I was under the impression that in buildings taller than two stories high, service riser cupboards should have fire stopping between levels as to enable compartmentation. I’ve just just been carrying out some work in a hotel which is four stories tall and the service risers do not have any between level stopping in place. You can see all the way down the riser shaft from top to bottom. Is this not an issue? This was not picked up in previous fire risk assessments. The riser shaft is situated in a communal area of the hotel e.g. a shared corridor leading to the hotel rooms. The doors leading to the riser shaft are fd30 doors but I was still under the impression between level fire stopping should be in place?

Thanks,

Jack.

The riser is considered a protected shaft. More important will be the standards of fire stopping/compartmentation around the riser cupboard and door leading to the stair lobby/MoE.
