Prac-tical experience typically includes production, sampling andanalysis of clandestine laboratory training samples.4.4 Laboratory management shall ensur

17、e that chemicalsafety and hygiene plans address and mitigate hazards associ-ated with clandestine laboratory evidence.4.5 Laboratory management shall consider customer/localrequirements which influence the application of these recom-mendations.5. Safety5.1 This guide does not purport to address all

18、of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this guide to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.5.2 Many items seized at clandestine laboratories may beintrinsically da

19、ngerous. These may include items of unknowncomposition and chemicals that have not been fully character-ized and whose specific hazards are not known. Therefore,caution must be exercised and routine safety protocols may notbe sufficient.5.3 The following are required in addition to the routinelabora

20、tory safety program in place for the analysis of seizeddrugs (see Practice E2327, Health and Safety):5.3.1 Safety procedures and the use of safety and protectiveequipment for all staff responsible for handling items;5.3.2 Protective breathing equipment;5.3.3 Listings of the relevant hazards (for exa

21、mple, MSDS)associated with components commonly found at clandestinelaboratory sites and knowing what they mean; and5.3.4 Accident prevention, emergency response procedures,and incident reporting protocols.5.4 The handling, analysis, and storage of items seized fromclandestine laboratories require ad

22、ditional procedures, facili-ties and equipment (see Practice E2327, Physical Plant).Examples are:5.4.1 Specialized ventilation equipment (for example, fumehoods) to prevent exposure to harmful fumes and vapors;5.4.2 Provision of personal protective equipment such assafety glasses, chemical resistant

23、 gloves, laboratory coats,respirators, face masks, and air monitors;5.4.3 Maintenance of a clean, uncluttered workspace;5.4.4 Specialized emergency equipment stations;5.4.5 Chemical disposal and destruction facilities and pro-cedures; and5.4.6 Specialized evidence receipt, storage and disposalrequir

24、ements designed to mitigate expected dangers (forexample, limited sample size, proper packaging of reactivematerials, use of absorbents, properly ventilated storage).5.5 Analysts shall be aware of the hazards associated withclandestine laboratories samples. Examples are:5.5.1 Extracting from strong

25、acids and bases (for example,hydriodic acid, sodium hydroxide);5.5.2 Handling fuming acids and bases (for example, hy-drochloric acid, ammonia);5.5.3 Poisonous gases (for example, phosphine, chlorine,hydrogen sulfide) and their potential release from evidenceduring analysis;5.5.4 Poisonous, carcinog

26、enic, and mutagenic materials (forexample, mercuric chloride, chloroform, potassium cyanide);5.5.5 Reactive and air sensitive materials (for example,white phosphorus, lithium);5.5.6 Potential testing incompatibilities (for example, phos-phorus with Raman, color test reagents with cyanide salts,exoth

27、ermic reactions);5.5.7 Radioactive materials (for example, thorium); and5.5.8 Volatile and flammable solvents (for example,acetone, diethyl ether, methylated spirits).6. Sample Section for Analysis6.1 The primary purpose of analysis is to prove or disproveallegations of clandestine drug syntheses. A

28、ccordingly, ana-lysts must select items which relate to the manufacturingprocess.6.2 Not all items seized at a clandestine laboratory site mayneed to be analyzed. It is recommended that information beshared between the analyst and on-scene personnel to aid insample selection.6.3 Items should be sele

29、cted for analysis, based on jurisdic-tional requirements, and which are likely to contain:6.3.1 Finished product,6.3.2 Intermediates,6.3.3 Precursors,6.3.4 Key reagents, and6.3.5 Reaction mixtures.6.4 Some of the following types of items may be analyzedas they can assist in determining the chemical

30、reaction(s)undertaken and the scope of the clandestine laboratory:6.4.1 Materials that appear to be waste;6.4.2 Unlabeled materials that appear to be contaminatedsolvents, acids, or bases; and6.4.3 Samples from contaminated equipment.6.5 Items that are readily obtained from local retail storesand ar

31、e sold from reputable manufacturers/distributors may notneed to be analyzed, particularly if collected from sealed andlabeled containers. These include:6.5.1 Solvents (for example, toluene, mineral spirits),6.5.2 Acids (for example, hydrochloric acid, sulfuric acid),and6.5.3 Bases (for example, sodi

32、um hydroxide, ammoniawater).7. Analysis7.1 Substances whose presence are reported or contribute toformulating reported conclusions shall be identified with anadequate analytical scheme.7.2 Where possible, the identification of organic compoundsshall follow the guidelines for the analysis of seized d

33、rugs (seePractice E2329).7.3 The discriminating power of analytical techniques forthe identification of inorganic materials depends on the par-ticular analyte. In each case the analytical scheme shall:E2882 1227.3.1 Have sufficient discriminating power to identify thematerial to the exclusion of oth

34、ers (for example, identificationof both the cation and anion in salts), and7.3.2 Utilize two or more techniques, preferably from dif-ferent analytical groups described below.7.4 The following list of analytical groups and techniquesare in no particular order and are not exhaustive. Analyticaltechniq

35、ues must be selected which provide sufficient discrimi-nating power for each analyte. Some techniques may not beuseful for particular analytes and each must be evaluated todetermine suitability.7.4.1 Analytical Group 1: Elemental Analysis TechniquesThese techniques may provide positive results for e

36、lementspresent in a sample but typically require additional tests todistinguish forms (for example, oxidation state).7.4.1.1 Atomic absorption spectroscopy,7.4.1.2 Atomic emission spectroscopy and flame tests (anattached spectrometer significantly increases the discriminat-ing power relative to flam

37、e tests),7.4.1.3 Energy dispersive X-ray detectors for scanning elec-tron microscopes,7.4.1.4 Mass spectrometry (utilizing inductively coupledplasma sources or for elements with unique isotopic abundancepatterns), and7.4.1.5 X-ray fluorescence.7.4.2 Analytical Group 2: Structural ElucidationTechniqu

38、esThese techniques may have high discriminatingpower for polyatomic analytes.7.4.2.1 Infrared spectroscopy,7.4.2.2 Mass spectrometry,7.4.2.3 Nuclear magnetic resonance,7.4.2.4 Raman spectroscopy,7.4.2.5 UV-vis and fluorescence spectroscopy, and7.4.2.6 X-ray diffractometry.7.4.3 Analytical Group 3: S

39、eparation TechniquesThesetechniques can be valuable for mixtures and for distinguishingdifferent forms of an element (for example, phosphate andphosphite).7.4.3.1 Capillary electrophoresis,7.4.3.2 Gas chromatography,7.4.3.3 Ion Chromatography7.4.3.4 Liquid chromatography, and7.4.3.5 Thin layer chrom

40、atography.7.4.4 Analytical Group 4: Chemical PropertiesThesetechniques involve observations of chemical changes. Utilizingseveral of these techniques, in series or combination, can oftenincrease discriminating power.7.4.4.1 Flammability;7.4.4.2 Microcrystalline tests;7.4.4.3 pH (of liquids or vapors

41、);7.4.4.4 Radioactive decay;7.4.4.5 Reactivity with water, air, or other materials;7.4.4.6 Solubility and miscibility tests; and7.4.4.7 Spot and precipitation tests.7.4.5 Analytical Group 5: Physical PropertiesThese tech-niques involve observations of physical properties. The dis-criminating power o

42、f these techniques depends on the measur-ing device.7.4.5.1 Color;7.4.5.2 Crystal forms measured with polarized light micros-copy;7.4.5.3 Density (relative density and density of mixtureshave reduced discriminating power);7.4.5.4 Phase transitions including melting points, boilingpoints, sublimation

43、 temperature, and vapor pressure;7.4.5.5 Physical state or states;7.4.5.6 Refractive index; and7.4.5.7 Viscosity and surface tension.7.5 If limited or qualified conclusions are sufficient (forexample, basic aqueous layer, non-polar organic solvent, amaterial containing the element phosphorus), tests

44、 of limiteddiscriminating power may be utilized within an analyticalscheme.7.6 Analytical reference materials may not be available forthe analysis of intermediates and byproducts. In these cases,samples taken from a test reaction in conjunction with suitablereference literature may be used for compa

45、rison purposes.7.7 Quantitative measurements of clandestine laboratorysamples have an accuracy which is dependent on sampling and,if a liquid, on volume calculations. Accordingly, these mea-surements and calculations may be based on estimates. Underthese conditions, a rigorous calculation of measure

46、ment uncer-tainty is often not possible or necessary and the uncertaintymay best be conveyed by using a qualifier statement on thereport (for example, approximately, not to exceed, no lessthan).8. Yield and Capacity Calculations8.1 Yield and capacity calculations can be achieved from anumber of appr

47、oaches and shall be based on relevant caseinformation, suitable literature, laboratory and jurisdictionalrequirements.8.2 Reported yields and capacities shall be based uponinformation documented in the laboratory case file.8.3 Calculated yields can be expressed as theoretical orexpected.8.3.1 It is

48、recommended that reported yields be accompa-nied with an explanation clarifying the limitations or consid-erations.8.3.1.1 Theoretical yields are calculated based on theamount of known chemical, the stoichiometry of the reactionused in the clandestine laboratory and the product. Theoreticalyields ar

49、e not achievable in practice and their reporting can bemisinterpreted.8.3.1.2 Expected yields are calculated based upon publisheddata, experience, or practical experimentation. Expected yieldscan be highly variable based upon the factors listed below.8.4 In calculating expected yields and capacities in clandes-tine laboratories, many different sources of information can beused. Each case is different and will have a different set ofevidence from which to draw information, including, but notlimited to:8.4.1 Amounts of finished products, precursors, or essentialchemicals p
