2.2 Safety
instructions
•
When using the ashing device in surroundings with increased safety requirements, pay careful
attention to the appropriate regulations.
•
Only set it up in a room which is adequately spacious, dry and well ventilated.
•
Only operate the device upright on its stand and on a stable, level base.
•
Atmospheric contamination may only be non-conductive. Short-term conductivity caused by
condensation may only arise occasionally.
•
The device may not be operated or stored in a corrosive or explosive atmosphere (dust,
steam, gas).
•
Never operate the device with a faulty mains lead.
•
Never lay the mains cable over sharp corners and edges or hot surfaces.
•
If there is any reason to believe that it is no longer possible to operate the device safely,
unplug it immediately from the electricity supply (pull out the mains cable) and secure it so that
it cannot be operated inadvertently.
•
During operation and maintenance work, take particular care with hot parts, in particular in the
area of the furnace chamber (risk of burning).
•
When the furnace chamber is opened whilst the machine is in operation or after the end of the
trial, very hot air will escape, and the furnace chamber will radiate intense heat.
•
Do not place or stand objects of any kind on the lid of the ashing device. Do not subject the lid
to any mechanical pressure. Heat must be allowed to radiate freely from the machine during
operation.
•
Sample type: do not ash any explosive samples.
•
Have an electrician check that the entire electrical system is working properly before the
ashing device is first commissioned, after maintenance and servicing work on the electrical
system and at intervals of at least every four years.
