In response to the Grenfell Tower tragedy, Council Leader Cllr Stephen Cowan said “The fire in Kensington has made one thing clear – just meeting minimum fire standards is not enough. The regulations are clearly not good enough so we will be going above and beyond what is required.” Minimally complying with room integrity testing is not enough. As building age or their internal use is changed leak sites develop and the threat to people becomes high.
To understand how fire resistant a compartment is, an inspection of the overall condition of the existing fire compartments is needed, as well as an assessment of the condition and effectiveness of the sealing of wall/soffit interfaces and an inspection of existing fire seals applied to service penetrations through fire compartment lines. Issues in the quality of compartmentation walls can come from maintenance, minor works and refurbishments. Contractors carrying out such tasks can occasionally destroy the compartmentation integrity of the wall, floor or ceilings if they were unaware that the area is a comparted space (as shown in the below image). Therefore, following maintenance it is “good practice” to ensure the fire resistance of walls, floors and ceilings and to safeguard again if necessary. But what if this “good practice” is ignored, as it so frequently is, and there is a fire? The gaseous extinguishing system may not be able to control the fire.
Coltraco Ultrasonics have provided a smart solution to quick and easy assurance of compartmentation. The Portascanner® 520 uses ultrasonic Hatch Cover Tester technology to not only pinpoint precise leak locations, but to determine their leak apertures as small as 0.06mm with a tolerance of +/-0.02mm, it is by far the most mathematically proven accurate device for this function.
