WARNING
Ignition of flammable chemicals!
●
This instrument is not explosion-proof.
During unmanned operation, avoid use of organic
solvents having an ignition point below 70
°
C.
●
Beware of an ignition hazard when using flammable
chemicals such as organic solvents.
(a) Do not bring a flame source near the instrument.
(b) Ventilate the laboratory room adequately.
(c) Always check the following conditions, and if an
abnormality is found, stop operation at once.
•
Leakage of solvent or waste solution
•
Leakage of solvent inside the instrument
●
Beware of an ignition hazard due to static electricity
when using flammable chemicals.
To prevent a build-up of static electricity, use a
conductive container for waste solution and provide
proper grounding connection to it.
WARNING
Explosion of vapor from flammable chemicals!
If a flammable chemical such as organic solvent leaks from
the flow path of the instrument and its vapor concentration
reaches the explosion limit, it could cause spontaneous
combustion with dangerously explosive results.
When using a flammable and readily volatile chemical, be
sure to check for leakage from the instrument flow path
and ventilate the laboratory room adequately.
