Change of Building Use
Fire Safety Systems

Many ‘change of building use’ projects come with unique demands. The iMist system is used in many of these projects across the UK due to its ‘easy to retrofit’ properties.

Protecting your investment

For ‘change of building use’ projects, it is important to follow all fire safety regulations to fully protect the property. Many types of conversion can be undertaken to change a property’s usage and most will require Building Control approval.

From barn and church conversions to windmills and water towers, iMist have many years of experience in installing fire suppression systems in existing properties. Often, these types of property conversions will have heritage roots and therefore they will require a careful installation that does not disturb the existing structure.

Why is a Fire Suppression System needed?

BS:9991 says you must have an AWFSS in the following circumstances;

 

5.2.1.2 Multi-Basement Buildings

For dwellings with multiple floors below ground level, a protected stairway, and an AWFSS is required. 9 meters should not be exceeded from the foot of the protected stair to any habitable room.

6.4 (b) Dwelling Houses with one or more storey greater than 7.5m in height (4 storeys)

A second, separate protected stairwell is not required if AWFSS is fitted throughout.

9.1 (d) Internal Planning of Flats and Maisonettes

Flats or maisonettes with an open plan arrangement and more than one floor should have a protected stairway and AWFSS fitted. This allows escape to the shared external entrance.

9.4.2 (a) Extended travel distances within an open-plan flat

Flats more than 4.5m above ground level that are entered on the same level can increase total travel distances to the entrances from 9m to 20m with the use of AWFSS throughout the entire building, along with a LD1 fire detection and fire alarm system in accordance with BS 5839-6:2013.

9.3 (b) Provision of inner rooms in flats not more than 4.5m in height

Inner rooms are not suggested unless the use of an AWFSS is utilised throughout the entire building, along with a grade D LD1 Fire detections and fire alarm system in accordance with BS 5839-6:2013.

9.7 Open Plan Layouts

Open planned flats are permissible with a fully fitted AWFSS.
