Summary of Practice4.1 The drum and its contents are inspected, and

16、appropriatesampling equipment is selected. A clean device is then used toauger, chisel, chip, or core into the consolidated solid materialto be sampled. The sample is collected and placed in a samplecontainer. The sampling device is then cleaned and decontami-nated or disposed of.5. Significance and

17、 Use5.1 This practice is intended for use in collecting samples ofconsolidated or compacted materials from drums or similarcontainers, including those that are unstable, ruptured, orcompromised otherwise. Special handling procedures (forexample, remote drum opening, overpressurized drum open-ing, dr

18、um deheading, etc.) are described in Drum HandlingPractices at Hazardous Waste Sites.6. Interferences6.1 The condition of the materials to be sampled and thecondition and accessibility of the drums will have a significantimpact on the selection of sampling equipment.7. Pre-Sampling7.1 General Princi

19、ples and Precautions:7.1.1 Samples should be collected in accordance with anappropriate work plan (Practice D 5283 and Guide D 4687).This plan must include a worker health and safety sectionbecause there are potential hazards associated with openingdrums as well as potentially hazardous contents. Se

20、e Occupa-tional Safety and Health Guidance Manual for HazardousWaste Site Activities for information on health and safety athazardous waste sites.7.1.2 Correct sampling procedures must be applied to theconditions as they are encountered. It is impossible to specifyrigid rules describing the exact ma

21、nner of sample collectionbecause of unknowns associated with each solid samplingsituation. It is essential that the samples be collected by atrained and experienced sampler because the various condi-tions under which drummed solids must be sampled.7.1.3 To be able to make probability or confidence s

22、tate-ments concerning the properties of a sampled lot, the samplingprocedure must allow for some element of randomness inselection because of the possible variations in the material. Thesampler should always be on the alert for possible biasesarising from the use of a particular sampling device or f

23、romunexpected segregation within the material.7.1.4 All augering, chipping, or flaking sampling methodsmay fail a prime sampling requirement: that of randomselection of sample fractions. Particles on the bottom or alongthe sides of the drum may consequently never have anopportunity to be included in

24、 a sample. Sample particles shouldbe selected by techniques that will minimize variation inmeasured characteristics between the available fractions andthe resulting sample (Practice C 702).7.1.5 The sampling equipment, sample preparation equip-ment, sample containers, etc. must be clean, dry, and in

25、ert tothe material being sampled. All equipment, including samplecontainers, must be inspected before use to ensure that they areclear of obvious dirt and contamination and in good workingcondition. Visible contamination must be removed, and theequipment must be decontaminated with the appropriate r

26、insematerials. Decontaminated sampling equipment should beprotected from contamination. This may include, but not belimited to, storage in aluminum foil, plastic bags, polytetrafluo-roethylene (PTFE) film, or other means of protection that willnot impact the sample quality or intended analysis.7.2 B

27、asic Pre-Sampling Practices:7.2.1 Review all paperwork.7.2.2 Select the sampling equipment and sample containersappropriate for the material in the drum, as detailed in the workplan.7.2.3 Enter the work zone.7.2.4 Inspect all drums to be sampled visually. Note anyabnormal conditions, including rust

28、marks, stains, bulges, orother signs of pressurization or leaks that may require specialhandling. The work plan should define clearly the limitingconditions under which special handling procedures shall beinitiated. See Drum Handling Practices at Hazardous WasteSites for information on opening overp

29、ressurized drums andthe use of remotely operated drum opening equipment.7.2.5 Stage the drums to be sampled in a designated workarea if they cannot be sampled in their current location. SeeDrum Handling Practices at Hazardous Waste Sites for furtherinformation on staging drums.7.2.5.1 Move the drums

30、 to upright stable positions if nec-essary. Sufficient space shall be left between drums to preventmovement hazards.7.2.5.2 Number or identify uniquely all drums to besampled.7.2.6 Perform a detailed inspection of individual drums.7.2.6.1 Record all relevant information from the drumlabels, markings

31、, data sheets, etc. in the field log book or onforms specified in the work plan.7.2.6.2 Make sure there are no discrepancies with existingpaperwork.7.2.7 Slowly loosen the ring that secures the lid or loosenthe bung, allowing any pressure or vacuum to equalize.7.2.7.1 Precautionary Notes:(1) If the

32、drum or pail appears to be under positive ornegative pressure (that is, a slight lid bulge or dimple), controlthe release of pressure until it has equalized. For example, ifthe drum or pail is equipped with bungs, loosen the smallerbung first since doing so will make it easier to control therelease

33、of pressure.(2) If the tope of the drum is dished inward (dimpled), itmay “pop” when equalizing pressure, spraying the samplerwith any material that is sitting on top of the drum.(3) If there is evidence of a chemical reaction or suddenpressure buildup, the sampler should leave the area immedi-ately

34、 and evaluate whether remote drum opening equipmentshould be used.(4) For flammable or explosive materials, the drum andsampling equipment should be grounded if the generation ofstatic electricity while opening or sampling the drum is aD 5679 95a (2006)2possibility. The drum and sampling equipment s

35、hould begrounded to a ground stake or to an existing ground (buildingground, grounded water pipes, etc.). New sampling equipmentmay have some residual static electrical charge due to thematerials in which they are packed and shipped. The work planshould specify whether grounding is necessary. See Ac

36、cidentPrevention Manual for Industrial Operations for informationon grounding and bonding.7.2.7.2 Drums should be opened, sampled, and closedindividually to minimize the risk of exposure.7.2.7.3 Drums (or Pails) with BungsLoosen the largebung slowly. Use non-sparking tools.7.2.7.4 Drums with Removab

37、le LidsLoosen the ringslowly with a manual wrench or air impact wrench. Usenon-sparking tools.7.2.7.5 Pails with Removable Lids (Side-Lever LockRing)Release the lever slowly.7.2.7.6 Pails with Removable Lids (Snap-On)Pry the lidloose slowly with a pail lid opener.7.2.8 Manual or remote puncturing or

38、 deheading will berequired if the drum (or pail) has a stuck bung or the lid cannotbe removed. See Drum Handling Practices at HazardousWaste Sites for further information on manual or remote drumopening.7.2.9 Any discrepancy discovered (such as evidence of freeliquid) upon opening the drum should be

39、 recorded in the fieldlog book.7.3 Sampling EquipmentSelection:7.3.1 Table 1 summarizes selection criteria for equipmentby the material to be sampled.7.3.2 Sampling Equipment, Materials of ConstructionSampling devices will usually be made of stainless steel, brass,aluminum, or plastic. Devices using

40、 permanent coatings orliners (such as PTFE) may be subject to abrasion, leading tocontamination of the sample.7.3.3 Generic Equipment ListA general list of equipmentused for sampling consolidated solids follows:7.3.3.1 Scoop.7.3.3.2 Rotating corer.7.3.3.3 Thin-wall tube sampler.7.3.3.4 Chipper.7.3.3

Sample Collection8.1 Basic Sampling Practices:8.1.1 Bond the sampling equipment to the drum, if specifiedin the work plan.8.1.2 Note the physical characteristics, including any dis-crepancies (such as free liquid).8.1.3 Collect the required number of samples from thedrum.8.1.3.1 See Practice D

45、 4547 for the collection of samples forvolatile analysis.8.1.4 Place the collected material in a sample container.8.1.5 Close the sample container.8.1.6 Wipe the outside of the sample container. Dispose ofthe wipe cloth properly.8.1.7 Record in the field log book all relevant conditionsassociated wi

46、th the collection of each sample.8.1.8 Fill out all required paperwork for each sample, asrequired by the work plan.8.1.9 Complete and attach the label to the side of the samplecontainer before or after sampling, as directed by the workplan.
