The questions in this area are intended to identify the laboratory staff's knowledge of the analysis of
silica, the associated problems, and potential solutions.
Any sampling situation can be rift with potential problems, such as:
The analytical problems presented by a given sample will depend on the techniques used
by the laboratory for the analysis. If they are not knowledgeable about the method they
are using and its limitations, the possibility for incorrectly analyzing the samples
increases. Similarly, knowledge of the sampling method and the workplace will aid the
laboratory personnel in identifying potential problems prior to beginning sample analysis.
In some instances, this will allow the method to be judiciously modified in order to
minimize the problems.
- What materials are in use in the workplace that might interfere with the analysis of
- Will the operations being monitored produce excessive levels of dust?
- In light of the interferences that may be present, will the analytical method identify
silica at a low enough level?
Experience with the analysis of samples for silica is an indication of the knowledge an
individual or organization has had an opportunity to gain. Experience is a difficult
parameter to measure; length of time or number of analyses are often a good gauge.
