Fire stopping/compartmentation in service risers.

[Jack Atkinson]

Hi, I hope you can help?

Should service riser cupboards in tall buildings (above two stories) have fire stopping fitted between the levels to establish compartmentation? I was under the impression they should if they were taller than two stories high yet I’m carrying some work out in a hotel and I can see all of the way down from the top (4th floor) to the bottom (ground floor). The riser shaft does have fd30 doors fitted at each access point but I was still under the impression that they required between level stopping? The riser shaft is situated in a communal corridor to the hotel outside of hotel room entrances.

Thanks,

Jack.

My understanding is if the shaft is a protected shaft is does not require compartmenting at each floor level.

As Tom said, not required.
