好色先生TV clients have been urged to carry out checks and repairs 鈥渨ithout delay鈥� on ventilation systems, after life-threatening defects were found in a large number of buildings.

According to the 好色先生TV Engineering Services Association (BESA), annual inspections by maintenance contractors revealed that 鈥渁 huge number鈥� of fire and smoke dampers had been incorrectly installed, posing a serious fire safety risk.

The urgency of the problem has led BESA to issue an interim technical bulletin (VH001) ahead of a full update of its industry guidance for fire and smoke damper installation (DW145) which will be delivered at its conference in October.

Graeme Fox, BESA鈥檚 head of technical, explained that the association had been alerted to 鈥渢he very dangerous practice鈥� of using self-drilling 鈥榯ek鈥� screws which do not melt when temperatures rise during a building fire 鈥� thus preventing the spring-loaded dampers from being released to contain the spread of the fire.

鈥淒ampers must be secured by fusible fixings that allow the duct to break away otherwise the collapsing duct could pull the damper out of place and break the seal between the fire zones,鈥� Fox added.

He said remedial action should be taken 鈥渨ithout delay鈥� to ensure compliance with manufacturer instructions.

鈥淲hile this is clearly a very worrying situation, we can take some reassurance from the fact that this problem is being brought to our attention by the increasing frequency of fire damper inspections and tests as awareness grows of this extremely important issue,鈥� he said.
