Apartments and Flats

Apartments and flats are the home of many families and can be devastating to many in the event of a fire. There have been various historic fires in high-rise buildings, which have changed the course of building regulations and fire safety laws surrounding them.  

When a fire starts in one room in a high-rise flat, it can spread across various rooms if they’re not effectively covered and destroy the lives of multiple families.

The addition of a fire suppression system, such as iMist can assist with suppressing fires before they grow too large and spread. This in itself can give the residents in a block of flats time to evacuate the building and will not cause further damage to surrounded properties, through water damage

When do I need a fire suppression system?

BS 9991 says you must have an AWFSS in the following circumstances; Multi-Basement Buildings

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

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. 

9.3 (d) 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 detection and fire alarm system in accordance with BS 5839-6:2013.

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 an AWFSS throughout the entire building, along with a LD1 fire protection and dire alarm system in accordance with BS 5839-6:2013.

9.7 Open Plan Layouts

Open planned flats are permissible with a fully fitted AWFSS.

11.1 Flats where occupants are not capable of independent evacuation 

It is possible to use provisions of an AWFSS where the use of the building is required for people not capable of independent evacuation (excluding common corridors and stairways). It is further possible to protect common areas (excluding common corridors and stairways) using provisions of an AWFSS where the use of the building is required for people not capable of independent evacuation. 

Our fully-qualified iMist engineers have successfully installed 2,000 domestic iMist fire suppression systems in apartments and flats so far. 

Unlike sprinkler companies, we do not charge for designs for our family home proposals to show you where our nozzles and pumps will be located.

Following your acceptance of our design package, a free site visit will be required before commencing works, and formal signing of contracts.

Apartment Case Study

We often receive enquiries for open plan flat living spaces, with different architects always trying new layouts. This project we received for central Manchester, required coverage because of the escape route from the bedrooms passing through the open plan kitchen and living area

As you can see, nozzles were placed throughout the flat, which enabled them to have the open plan area, the key selling point for this project.
