Passive Fire Protection

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.  The Ritherdon range of passive fire protection products has grown from the need to provide fire rated covers for new kinds of breach being discovered in fire risk assessments.

In many buildings walls and floors have been breached for example by in-set electricity meter boxes, 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 rated access panel – first and many hundreds of these units have been used to upgrade passive fire protection of meter boxes and riser access panels throughout buildings in the UK.

From this first passive fire protection product we have developed the following fire rated products:

  • fire rated R5 meter box,
  • the Riser FireSeal which is a new method of preventing the spread of fire in buildings through the risers and went on to be a finalist in the Security and Fire Excellence Awards – Passive Fire Innovation of the Year 2015,
  • the R22 FireSeal – a fire rated version of our standard R22; used to repair damaged gas meter boxes.  The R22 FireSeal has also been nominated for the Passive Fire Innovation of the Year award 2016.

All the FireSeal products are tested to the appropriate EN fire resistance testing standards as recommended in the BS 9999:  2008 Code of Practice:  EN 1363, EN 1364 and EN 1366. All the testing reports are available in our  Technical Information page.

The Ritherdon FireSeal, fire rated access panel has been tested in various sizes. In accordance with the test, all products within the following size range will comply with aforementioned standards: Minimum 283mm height x 201mm width x 52 mm depth and maximum 1500mm height x 1000mm width x 152mm depth.
