BBA-conference on technical risks on February 7th including round table of safety experts

Safety is a high good that we take for granted. But new technologies often produce new dangers no one thought of in the first place. Dense building envelopes, walls and windows prevent sufficient air exchange. In consequence, harmful gases (toxic or explosive) such as natural gas, carbon monoxide or LPG can gather in the rooms especially when the air conditioning is turned off or out of order.

On February 7th, 2019, the educational institute Berlin-Brandenburgische Akademie der Immobilienwirtschaft (BBA) held a conference at the Grand Hotel Esplanade in Berlin on safety topics of operator's responsibilities such as fire protection, carbon monoxide detectors, checks of gas pipes and drinking water installations for potentially pathogenic germs.

The expert panel that concluded the conference circles aorund the question whether the price for safety is too high considering the declining number of accidents.

Innovation 2018: new cooling box made of aluminum weighs only 5,5 kg

The first series of our Passive Cooling Device (PKA) has done an excellent job for almost six years. But it has come of age; the first boxes show significant signs of material fatigue and damages (loss of water, broken weldings, etc.). In addition, the high weight of the steel case of 9,6 kg started to cause health problems at some samplers.

So, in November 2018, the executive management decided to replace the steel with aluminum and create a new, considerably lighter series of PKA 2.0 bringing only 5,5 kg on the scale. The prototyp has been tested for three months now. The new cooling devices will be iussed to the samples April 1st, 2019.

Follow-up study on legionellae shows seasonal effect: 20% less contaminations detected during the summer
On January 31st, Professor Kistemann from the Institute for Hygiene and Public Health of University of Bonn (ihph) presented first results of the follow-up study on legionellae occurence and growth in domestic drinking water installations (warm water systems) for the sponsors of the study being all members of the work group water analytics of figawa, the German Associations of firms in the gas and water sector.

Compared with the initial study the quality of the data provided and assessed was significantly better. Almost every single drinking water data set could be assigned to the different sampling points: drinking water heater outlet, re-entry in the drinking water heating system and peripheral tapping points (often in apartments).

The rate of samples that exceeded the threshold value of 100 colony forming units per 100 ml drinking water was at 6% a little bit higher than the rate of the former study (5,6%).

What was scientifically interesting is the fact that a seasonal effect was proven: In the summer the occurence of legionella exceeding the 100 CFU-limit was 20% higher than in the winter. Referring to Prof. Kistemann the difference is statistically significant since the data base consisted of 305,000 water samples and test results.

Industry

Although coming from the housing sector we have seen an increase in business relations with industrial  enterprises. Before the German drinking water directive passed the Bundesrat firms of the producing and processing industry have always been very sensitive for safety issues. Labor protection laws ordered them to have the water used or processed tested for potentially pathogenic bacteria.

Gas leak detection with GAS-Control

WATERcontrol has evolved from the "big sister" GAS-Control GmbH, a specialist for preventive gas safety checks within builidngs. GAS-Control has worked for the German housing industry for 25 years.

To detect gas leakages, even on concealed lines, the firm operates with portable gas leak detectors that pinpoint tracers of natural gas where they escape from the pipe.
