6.1 Safety information for commissioning
Introduction of combustible gases
Danger of explosion
The device is
designed for measurement of ignitable gas mixtures.
•
If the device is used to measure flammable gases that can combine with air or oxygen to
form an ignitable gas mixture, take special explosion protection measures!
Dangerous concentration of hydrogen
Danger of explosion
Hydrogen (H
2
), among others, serves as a supply gas for operation of the FIDAMAT.
Hydrogen combines with the oxygen in ambient air to form an explosive gas mixture.
Because hydrogen is usually supplied from high-pressure gas cylinders, you must ensure
that the quantity of hydrogen needed is limited.
• Ensure limiting of the hydrogen quantity, e.g. by using a suitable reducing valve.
Leaking of toxic gases from exhaust gas lines
Danger of poisoning
When toxic or aggressive gases are measured, they may be released through leaky
exhaust gas lines.
• Use parts made of sample-gas-resistant material for the exhaust gas lines (see section
Design of the device (Page 21)).
