SAFETY CONSIDERATIONS
PLEASE
READ
THESE
SAFETY
CONSIDERATIONS
CAREFULLY AND MAKE SURE YOU UNDERSTAND THEM
PROPERLY BEFORE YOU START OPERATING THE 1409
MULTIPOINT SAMPLER.
EXPLOSION HAZARD
THE 1409 MULTIPOINT SAMPLER IS NOT DESIGNED
FOR USE IN POTENTIALLY EXPLOSIVE
ENVIRONMENTS.
This means that the instrument must
not
be placed and operated in
an area with a potentially explosive atmosphere.
When monitoring potentially flammable or toxic gases it is essential
that:
1)
the instrument itself is placed in a well-ventilated area
outside
the
potentially hazardous zone; and
2)
a sufficiently long tube is connected to the “Sampler Waste Air
Outlet” so that the sampled gas is carried
away
to the open air or
to an extraction and/or filtration unit.
TO AVOID THE POSSIBILITY OF AN EXPLOSION, MONITORING OF
FLAMMABLE GASES
IN EXPLOSIVE CONCENTRATIONS
MUST
NEVER BE ATTEMPTED.
AVOID WATER CONDENSATION IN THE INSTRUMENT.
Liquids must be prevented from entering the instrument. It is therefore
important that warm humid gases be not drawn into a cold instrument
because condensation will take place. If such a situation is likely to
occur, you should ensure that the gases are drawn through water-trap
filters before they enter the sampler channels of the 1409. This will
remove water vapour in the gases and thus prevent condensation
within the instrument. The water-trap filter should be used in the
immediate environment of the instrument so it maintains either the
same temperature, or a lower temperature than the instrument.
Note:
that some gases may be absorbed by the water trapped in the
filter. This will reduce the gases’ concentration.
