1 Safety
Read the user manual before operating this instrument.
Do not install or operate this instrument unless you are trained to do so.
Always wear safety glasses and protective clothing when operating this
instrument.
Read the H
2
S (hydrogen sulphide) safety data section of the user manual before
using this instrument. H
2
S is an extremely hazardous and toxic compound, which
at very high concentrations can cause immediate death. Always use an H
2
S
monitor to alert you to an unsafe atmosphere when using this instrument.
This instrument is used to heat and test materials that may be flammable, toxic or
give off vapours and fumes. Use vapour extraction facilities and eliminate ignition
sources. Follow the guidelines in the user manual for handling flammable liquids.
Always use the instrument under a fume hood and connect the air outlet to a
fume extraction system. The exhaust gas contains H
2
S, which is toxic. Do not
touch surfaces that become hot during operation. Hot parts may reach
temperatures in excess of 80°C.
Use this instrument only as described the user manual. The intrinsic protection of
the unit may be impaired if it is not used as described.
Comply with any applicable local and national health and safety regulations when
installing or operating this instrument and when storing, handling and disposing
of samples. Always handle samples in accordance with the manufacturer’s
instructions.
Do not modify the instrument in any way as this may result in injury or damage to
the equipment and will invalidate the warranty.
Always allow the instrument to cool down and disconnect the electrical power
supply before cleaning, moving or maintaining it. Failure to do so may result in
death or serious injury.
This instrument is heavy. Do not attempt to lift it on your own. Two people are
required to lift the instrument. Always disconnect any accessories and remove
the test vessel and liquid trap before moving the instrument.
Use only the accessories and spares that are designed for use with the
instrument.
You are responsible for the safety of any external system to which the instrument
is connected. External systems may include but are not limited to computer
networks, laboratory information systems (LIMS), virtual network computing
(VNC) systems and fume extraction systems.
Carry out a risk assessment before using this equipment.
