- do not over-fill the tanks when they are inserted in the instrument.
- do not spill any liquids on the instrument.
2.4 RISKS DUE TO HIGH TEMPERATURES
The carousel is an exposed part of the instrument and is heated to a temperature that can vary from 25
to 40 °C during the test cycle, depending on the executed test.
Even though prolonged accidental contact with the plate in the area where the strips are inserted will
not cause burns, a label warns the operator of the danger of heated surfaces.
2.5 BIOLOGICAL CONTAMINATION RISKS
The material used in the tests is human serum and, as such, potentially infectious. All precautions
established by the relative local legislation for laboratories in the countries where the instrument is
used, must therefore be followed.
The waste material must also be treated as any other product that can be considered organic hospital
waste.
In the areas where contact with serum might occur, there is a label reporting danger of biological
contamination.
A sanitization cycle is available (see 3.6.4), using a special liquid which eliminates all harmful
microorganisms from the tubes and all the internal surfaces which are in contact with potentially
infectious liquids.
2.5.1 H
ANDLING THE STRIPS AND SERUM
Danger arises when handling the strips
• during serum dispensation in the first well of the strip;
• when the strip is inserted in the carousel, because the pressure exerted to insert the strip might
cause the liquid to spill whenever it was previously dispensed in the first well ;
• during the cycle, with the lid open, if a cycle that includes mixing was programmed, because the well
of the strips that protrudes is the one containing the serum; therefore operating with the lid closed is
recommended;
• during removing the strip from the carousel, because the force needed to extract the strip might
cause liquid to spill because a little unused liquid might be left in the well;
• during their disposal, after use, because they are lying around and not collected in the appropriate
containers.
2.5.2 H
ANDLING WASTE MATERIAL
The waste material of the instrument must also be handled the same as any other product considered
organic hospital discard.
In the zones where contact with the serum can occur, a label is attached indicating a biological
contamination hazard.
The dangers that can occur are:
