on their technical training and knowledge as well as knowledge of the relevant
regulations, can assess the tasks given and recognize the hazards involved.
WARNING
Health risk through contact with toxic gases
The modules and devices contain enclosed, potentially dangerous gases that can
escape should a defect or leak occur. If a leak occurs, the concentrations inside the
enclosed device can increase up to 40 ppm.
NO: 2 ml max. total volume
