H2 - Hydrogen gas
Hydrogen is easily combustible, and together with
oxygen, it forms the explosive oxy-hydrogen gas.
As the name suggests, a loud bang is heard when the gas is ignited.
The waste product in the reaction consists of water vapor.
When burning hydrogen in air, in addition to water, some other
substances are formed, mainly nitrogen compounds.
In a fuel cell you can make use of the energy which is formed in the
reaction with oxygen in the air without getting other waste products
than water.
Liquid hydrogen is used in rocket engines with liquid oxygen as
oxidizer.
A great deal of hydrogen used in the petroleum industry when "upgrading"
fossil fuels.
In the Fischer-Tropsch process hydro-carbons are formed from
hydrogen and carbon monoxide.
Another major use of hydrogen exists in the production of ammonia.
In the so-called Haber-Bosch process, nitrogen and hydrogen are
mixed and subjected to high pressure and high temperatures whereby
ammonia is formed.
N2 + 3H2
 2NH3
The ammonia can then be used for example to produce manure.
Hydrogen is also used in the production of hydrochloric acid,
methanol, and when hydrogenating fats.

ATEX Gas detectors are available for 2
explosion classes as follows:
Zone 1 is available with or without display .
Gas detectors for ATEX Zone 1 are located in a flameproof enclosure,
EEx d
The shell is such that ignition and
combustion within the shell of a potential explosive gas mixture is
not propagated to the explosive mixture outside the enclosure and
the enclosure can thus endure the resulting explosion pressure
without damage.
In Zone 1 ,
one can expect an explosive atmosphere to occur during normal
operation but the presence of it is relatively
short.
The equipment shall not be a source of
ignition in normal operation or when an error occurs.
Gas detectors for ATEX Zone 2 are of the
design Non-sparking EEx nA
EEx nA is a non-sparking piece
equipment.
In Zone 2, you need not count with an
explosive atmosphere to occur during normal operation, and if it
should occur, which is probably rare it is of
short duration.
The equipment shall not be a source of
ignition during normal operation.
