Operating precautions
1.
The fuel gases used in the flame photometers are inflammable and therefore potentially hazardous.
2.
It is possible that a small quantity of fuel will escape from the instrument during the ignition
sequence. The amount of fuel is harmless although may smell slightly. If the smell of fuel gas persists
the instrument should be immediately shut down and the source of the leakage determined by using
a soap solution on the hose joints.
3.
Do not leave the instrument running unattended while the flame is alight.
4.
The top of the instrument chimney unit becomes very hot when running and can cause severe burns
if touched.
5.
The exhaust gases from the flame are very hot and the area approximately 1 metre above the
chimney must be avoided. Never attempt to look down the chimney whilst the flame is running.
Always use the inspection window.
6.
The instrument uses potentially hazardous electrical supplies. Never remove covers from the
instrument without first ensuring that it has been isolated completely from the AC mains supply.
7.
If the instrument is used in a pathology laboratory, all samples should be handled with the caution
normally accorded to those known to contain pathogenic organisms. Care should also be taken
when undertaking maintenance on instruments that have been used in these environments. A
bactericidal agent should be used when cleaning parts during routine maintenance.
For detailed safety precautions please refer to the beginning of the manual, page 1 onwards.
