R22 FireSeal

A common issue being picked up in fire risk assessments is when gas meters have been installed along fire escape routes in multi-occupancy residential buildings. Standard gas meter boxes do not provide adequate fire resistance and it is recommended that these meters should be covered with a fire resistant box.  So Ritherdon designed and added the new R22 FireSeal to our passive fire protection range.

R22 FireSeal is a modification of our standard R22 meter box repair unit. Like the standard R22 unit, it is designed to be retrofitted and replace the old plastic box; in this case with a fire resistant box for the gas meter.  The R22 FireSeal features intumescent seals right around the door and between the back of the unit and the wall.

Ritherdon also developed a method of adaptable pipe entry points which are sealed with fire resistant filler after fitting. The R22 FireSeal has been tested in accordance with BSEN 1364-1: 1999 utilising the principles of BSEN 1366-3: 2009, providing a minimum of 90 minutes of fire resistance.
