Why self-retracting lifelines?
One of the most effective and widely used fall
arrest solutions today is the Self-Retracting
Lifeline (SRL). Accounting for around a fifth of the

Monitoring Of Indoor Air Quality Needs To
Measure More Than Just CO2
With ventilation continuing to dominate the news agenda, a leading
ventilation specialist is stressing the importance of monitoring
pollutants beyond just CO2. compounds (TVOCs). Given the main source of
some of these, natural ventilation such as opening
a window can actually have adverse effects
in certain locations e.g., city centres. In these
circumstances, mechanical ventilation offers the
most protection for building occupants.
Alongside pollutants, there is also the issue of
relative humidity (RH). Humidity levels in indoor
spaces play an important role, from supporting
good human health and wellbeing, to helping
preserve stored food, electronic equipment,
artwork etc. Too high humidity levels can cause
damp and condensation problems, and at the
opposite end of the scale, too low levels of
humidity can lead to a dryness of the skin, eyes,
nose and throat.
This is crucial, as the human body's first line of
defence against airborne agents (both chemical
and biological) is the mucosa lining at the top

Early and central fire gas detection
GSMX-P: Fire gas detection in filter systems
The handling of bulk solids poses many challenges. One of these challenges is the
enormous amount of dust that is created by conveying and processing the different
products. In order not to unnecessarily strain the process and employees on site and to
expose them to risks, these enormous amounts of dust get extracted.
Fig. 1: Phases if fire development
Fig. 2: GSMX-P design
How does the GSMX-P work?
The GSMX-P fire gas detector monitors the entire
cross-section of the clean gas / ventilation line.
For this purpose, it is attached to the line in a
separate housing. Two pipes protruding into the
clean gas / ventilation line generate continuous
air extraction over the entire cross-section using
the Venturi principle. The design not only enables
representative and reproducible monitoring, but
also dispenses with further electrical aids such as
pumps or fans.
Where is such system used?
Almost every process in every industry can be
monitored with a GSMX-P in a filter. Because it
