MRU GmbH

1.5. General warnings

Any maintenance action must be done only, when the
atmosphere is verified to be not explosive.
Apply personality safety equipment, against high H2S/CO
concentrations before open the device.
Under special conditions the device can accumulate with toxic
gases.
• Measure the atmosphere, around the device, before
• After the opening of the device, ventilate sufficiently.

1.6. Safety Information

The following safety procedures must always be followed. They are significant and
essential part of this manual. Failure to follow safety procedures can result in the loss of
your warranty claims.
Biogas or other similar gases (landfill gas, bio-methane, coal seam gas etc.) is containing
flammable gas component CH4 and toxic gas component as well (H2S and CO2).
Analyzers is continuously sampling a certain volume (approx. 50l/h) of the sample gas
and is venting it to ambient air.
For this reason, there are two aspects which must be considered:
1) toxicity danger of sample gas
2) flammable (explosion) danger of sample gas
1) Inhaling toxic gases is harmful to health and can even cause death in some cases.
•
It is the responsibility of analyzer user to ensure that person is skilled and
trained
follow while using this instrument.
•
Local regulations for possible exposition to toxic gases have to be known
and obeyed by the user of the analyzer
•
Using a personal gas detector inside the biogas plant is highly
recommended since
H2S in higher (very dangerous) concentration cannot be detected by
human nose. Only small concentrations around few ppm can be detected
by human nose
•
CO2 gas is heavier than air and therefore operator shall avoid working at
underground or confined spaces. Beside of that CO2 is also odorless!
•
It is not allowed using the biogas analyzer in confined space or rooms
without forced ventilation.
•
Sample gas exiting the analyzer will flow in the ambient air and only
outdoor use
or forced ventilation rooms are suitable for using the biogas analyzer
opening it.
