SAFETY CONSIDERATIONS
PLEASE READ THESE SAFETY CONSIDERATIONS CAREFULLY
AND MAKE SURE YOU UNDERSTAND THEM PROPERLY BE-
FORE YOU START OPERATING THE MULTIPOINT SAMPLER
AND DOSER TYPE 1303.
EXPLOSION HAZARD
THE MULTIPOINT SAMPLER AND DOSER TYPE 1303 IS NOT DE-
SIGNED 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) that 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 are 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 a water-trap filter
before they enter the sampler channels of the 1303. This will condense
out water vapour in the gases and thus prevent condensation within the
instrument. The water-trap filter should be used in the immediate envi-
ronment 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 fil-
ter. This will reduce the gases’ concentration.
