Fire safety smoke spread vaulted ceiling

[Guest Stephen]

Hi,

 

I'm looking some advice. I'm currently carrying out a fire risk assessment in a village hall. The main hall has vaulted ceilings which span across the main hall itself and the escape route. At ground level the hall is divided into two sections - main hall and escape corridor however, above ground floor ceiling height the ceiling is open. This means that a fire in the main hall could filter smoke into the escape route. There is a fire alarms system in place with detectors in each area. The escape corridor has two fire escape doors at each end of the corridor and the main hall also has a fire escape door too. I'm just a little concerned at how quickly the smoke could roll over the top of the dividing room which separates the escape corridor from the main hall and wondered if any additional measures need to be put in place such as.

Partitioning the two areas off

AOV system 

fire curtain etc

 

Any help would be appreciated

What are the travel distances to the final exit, is there more than one exit?

Depending on size a protected route may not be required and the partitioning is purely functional

Depending on the size you may be able to treat as an inner room, ADB 2.11
