Which of the following is required to ensure accurate sample tagging?

Accurate sample tagging is crucial in gas sampling as it ensures that the data collected can be reliably associated with the conditions under which the sample was taken. Relevant gas readings are essential for this process because they provide the specific details about the gases present at the time of sampling. These readings give context to the sample, including concentrations of various gases, which can indicate certain conditions within the mine environment. Proper tagging that includes this data aids in analyzing the results correctly and making informed decisions based on the sample.

While temperature, mine safety inspections, and the experience of the sampler contribute to overall sampling quality and safety, they do not provide the critical information needed for the accurate identification of gas conditions associated with the specific sample. Thus, the inclusion of relevant gas readings in sample tagging is what ensures that samples can be accurately interpreted and are linked to the correct sampling conditions.
