16、a plan specific to a particular site; forconducting activities specified in the plan.4. Summary of Practice4.1 The drum and its contents are inspected, and appropriatesampling equipment is selected. A clean sampling device isthen used to auger, scoop, or core into the unconsolidated solidmaterial to

17、 be sampled. The sample is collected and placed ina sample container. The sampling device is then either disposedof or cleaned and decontaminated.5. Significance and Use5.1 This practice is intended for use in collecting samples ofunconsolidated solid materials from drums or similar contain-ers, inc

18、luding those that are unstable, ruptured, or compro-mised otherwise. Special handling procedures (for example,remote drum opening, overpressurized drum opening, drumdeheading, etc.) are described in Drum Handling Practices atHazardous Waste Sites.6. Interferences6.1 The condition of the materials to

19、 be sampled and thecondition and accessibility of the drums will have a significantimpact on the selection of sampling equipment.7. Pre-Sampling7.1 General Principles and Precautions:7.1.1 Samples should be collected in accordance with anappropriate work plan (Practice D 5283 and Guide D 4687).This

20、plan must include a worker health and safety sectionbecause there are potential hazards associated with openingdrums as well as potentially hazardous contents. See Occupa-tional Safety and Health Guidance Manual for HazardousWaste Site Activities for information on health and safety athazardous wast

21、e 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 manner of sample collectionbecause of unknowns associated with each solid samplingsituation. It is essential that the samples be collected b

22、y atrained and experienced sampler because of the various con-ditions under which drummed solids must be sampled.7.1.3 To be able to make probability or confidence state-ments concerning the properties of a sampled lot, the samplingprocedure must allow for some element of randomness inselection beca

23、use 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 fromunexpected segregation within the material.7.1.4 All auger, trier, thief, and scoop methods may fail aprime sampling requirement: th

24、at of random selection ofsample fractions. Scoops are limited to use at or near the topsurface. Augers, triers, and thiefs are normally inserted in apresent pattern. Particles on the bottom or along the sides of thedrum may consequently never have an opportunity to beincluded in a sample. Sample par

25、ticles should be selected bytechniques that will minimize variation in measured character-istics between the available fractions and the resulting sample(Practice C 702).7.1.5 The sampling equipment, sample preparation equip-ment, sample containers, etc. must be clean, dry, and inert tothe material

26、being sampled. All equipment, including samplecontainers, shall be inspected before use to ensure that they areclear of obvious dirt and contamination and are in goodworking condition. Visible contamination shall be removed,and the equipment shall be decontaminated with the appropri-ate rinse materi

27、als. Decontaminated sampling equipmentshould be protected from contamination. This may include, butnot be limited to, storage in aluminum foil, plastic bags,polytetrafluoroethylene (PTFE) film, or other means of protec-tion that will not impact the sample quality of intendedanalysis.7.2 Basic Pre-Sa

28、mpling 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 marks, stai

29、ns, bulges, orother signs of pressurization or leaks that may require specialhandling. The work plan should define clearly the limitingcondition under which special handling procedures shall beinitiated. See Drum Handling Practices at Hazardous WasteSites for information on opening overpressurized d

30、rums 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 turns.7.2.5.1 Move the drums to upright,

31、 stable positions ifnecessary. Sufficient space shall be left between drums toprevent movement 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 drum labels,markings, data sheets, et

32、c. in the field log book or on formsspecified 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 drum or pail appe

33、ars to be under positive ornegative pressure (that is, a slight bulge or dimple in the lid),control the release of pressure until it has equalized. Forexample, if the drum or pail is equipped with bungs, loosen thesmaller bung first since doing so will make it easier to controlthe release of pressur

34、e.(2) If the top 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 and evalua

35、te whether remote drum opening equipmentshould be used.D 5680 95a (2001)2(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 apossibility. The drum and sampling equipment should begro

36、unded 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.
