4.1 An analyst should be knowledgeable, through established laboratory training, of clandestine drug laboratory synthetic routes and the techniques used in the analysis of related samples. This acquired knowledge of clandestine drug laboratory samples assists the analyst in choosing the best analytical scheme to identify reagents, precursors, intermediates, and final products.

4.2 The qualitative and quantitative analyses of clandestine drug laboratory evidence can require different approaches relative to routine seized drug analyses. Analysts shall understand the limitations of the procedures used in their qualitative and quantitative analyses. These include such factors as method selectivity, uncertainty, and the basis for inferences from a sample(s) to a population.

4.3 Laboratory management shall ensure that clandestine drug laboratory synthesis and analysis training be provided through relevant procedures, literature, and practical experience. Practical experience typically includes production, sampling and analysis of clandestine drug laboratory training samples.

4.4 Laboratory management shall ensure that chemical safety and hygiene plans address and mitigate hazards associated with clandestine drug laboratory evidence.

4.5 It does not address scene attendance or scene processing.

4.6 Laboratory management shall consider customer/local requirements which influence the application of these recommendations.
