Summary of Practice4.1 The drum and its contents are inspected, and appropriatesampling equipment is selected. A clean sampling device isthen used to auger, shovel, scoop, or core into the unconsoli-dated

19、 solid material to be sampled. The sample is collected andplaced in a sample container. After use the sampling device isthen either disposed of or cleaned and decontaminated beforere-use.5. Significance and Use5.1 This practice is intended for use in collecting samples ofunconsolidated solid materia

20、ls from drums or similar contain-ers, including those that are unstable, ruptured, or compro-mised otherwise. Special handling procedures (for example,remote drum opening, over pressurized drum opening, drumdeheading, etc.) are described in EPA/600/2-86/013 DrumHandling Practices at Hazardous Waste

21、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 and techniquesused to recover representative samples.7. Pre-Sampling7.1 General Principles and Precautions:7.1.1

22、 Samples should be collected in accordance with anappropriate work plan (Practice D5283, and Guides D4687,D6044, D6051, D6063, and D6311). This plan must include aworker health and safety section because there are potentialhazards associated with opening drums as well as potentiallyhazardous content

23、s. See Occupational Safety and Health Guid-ance Manual for Hazardous Waste Site Activities for informa-tion on health and safety at hazardous 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

24、exact manner of sample collectionbecause of unknowns associated with each solid samplingsituation. It is essential that the samples be collected by 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 c

25、onfidence state-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

26、device or fromunexpected segregation within the material.7.1.4 All auger, trier, thief, shovel and scoop methods mayfail a prime sampling requirement: that of random selection ofsample fractions. Scoops and shovels are limited to use at ornear the top surface. Augers, triers, and thiefs are normally

27、inserted in a preset pattern. Particles on the bottom or along thesides of the drum may consequently never have an opportunityto be included in a sample. Sample particles should be selectedby techniques that will minimize variation in measured char-acteristics between the available fractions and the

28、 resultingsample (Practice C702). Many of these disadvantages may beeliminated if the drum contents can be emptied onto a protectedflat surface, allowing representative sampling of the disturbedpile using techniques described in Guides D6009 and D6323.7.1.5 The “Alternate Shovelling Technique” may b

29、e consid-ered for representative sampling of the unconsolidated contentsof drums or similar containers. If the investigation objectivesrequire statistically representative data to define the averageproperties of drummed contents, the sampling technique usedshould ensure that every particle size and

30、type is available forsampling. In the case of an open headed drum of unconsoli-dated solid materials, the materials from the drum should beremoved completely using a scoop or shovel, counting thenumber of scoop or shovel fulls required to do so. Materialfrom the drum should be placed either on plast

31、ic sheeting orinto another comparably sized clean drum. Based on the totalnumber of scoop or shovel fulls removed, various scoop/shovels should be selected systematically or randomly tosample as the material is being returned to the originalcontainer. These sample portions/aliquots from the scoops o

32、rshovels, corresponding to the systematic or random numbers,should be placed into the sample container. The number ofportions/aliquots needed is a function of the container size,particle size and sample size.7.1.6 The sampling equipment, sample preparation equip-ment, sample containers, etc. must be

33、 clean, dry, and inert tothe material being sampled. All equipment shall be inspectedbefore use to ensure that they are clear of obvious dirt andcontamination and are in good working condition. Visiblecontamination shall be removed, and the equipment shall bedecontaminated with the appropriate rinse

34、 materials. Decon-taminated sampling equipment should be protected from con-tamination. This may include, but not be limited to, storage inaluminum foil, plastic bags, polytetrafluoroethylene (PTFE)film, or other means of protection that will not impact thesample quality of intended analysis.7.2 Bas

35、ic 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.D5680 1027.2.4 Inspect all drums to be sampled visually. Note anyabnormal conditions, includin

36、g rust marks, stains, 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 EPA/600/2-86/013 Drum Handling Practices atHazardous Waste Sites for infor

37、mation on opening overpres-surized drums and the use of remotely operated drum openingequipment.7.2.5 Stage the drums to be sampled in a designated workarea if they cannot be sampled in their current location. SeeEPA/600/2-86/013 Drum Handling Practices at HazardousWaste Sites for further informatio

38、n on staging turns.7.2.5.1 Move the drums to upright, 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 i

39、nformation from drum labels,markings, data sheets, etc. 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

40、.7.1 Precautionary Notes:(1) If the drum or pail appears 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

41、 will make it easier to controlthe release of pressure.(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

42、sampler should leave the area immedi-ately 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 apossibility. The drum

43、and sampling equipment should 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 ground

44、ing is necessary. See AccidentPrevention 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.

45、2.7.4 Drums with Removable 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

See EPA/600/2-86/013 Drum Handling Practicesat Hazardous Waste Sites for further information on manual orremote drum opening.7.2.9 Any discrepancy discovered (such as evidence of fr

47、eeliquid) upon opening the drum should be 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,

48、brass,or aluminum.
