Sampling practice and theory

 · Sampling is defined as taking a small portion of a whole mass that accurately represents the whole mass. Very simple to define, however obtaining a representative sample is anything but simple. Mathematicians will say sampling is expressible as a series of mathematical equations. Such as, for sampling "X" pounds of material, one would take "y ...

Safe Operating Procedures Guide

Safe operating procedures should be reviewed on a periodic basis, e.g. every 2 years, depending upon the level of risk, to ensure that the procedure remains current and appropriate. Reviews of safe operating procedures will be required sooner than two years in the event: • An incident occurs that relates to the safe operating procedure ;


C. Determine if the mine operator is evaluating occupational exposures and tasks properly. Select appropriate methods for determining potential exposure such as area samples, personal samples, and appropriate control measures. Review the sample analysis results for accuracy, consistency, and regulatory compliance.
