In the event of a fire in a multi-occupancy building such as a block of flats it is essential that the fire is contained at source while it is extinguished and/or the building is evacuated. The Code of Practice for Fire Safety in Buildings (BS 9999: 2008) recommends that critical walls in a building should provide a minimum level of fire resistance.
In many buildings these critical elements of fire safety have been breached for example by electricity meter boxes set in to the walls, and dry risers and service risers running up through the building. Pathways like these for fire and smoke transmission are being identified in fire risk assessments but, for many of them, there has been no fire protection solution.
Ritherdon developed and tested the FireSeal – a fire and smoke resistant meter box door and frame unit – first and many hundreds of these units have been used to upgrade the fire resistance of meter boxes and riser access panels throughout the UK.
