16、cting activities specified in the plan.4. Summary of Practice4.1 The drum and its contents are inspected, and 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

17、 a samplecontainer. The sampling device is then cleaned and decontami-nated or disposed of.5. Significance and 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, orcompromi

18、sed otherwise. Special handling procedures (forexample, remote drum opening, overpressurized drumopening, drum deheading, etc.) are described in Drum Han-dling Practices at Hazardous Waste Sites.6. Interferences6.1 The condition of the materials to be sampled and thecondition and accessibility of th

19、e 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 D5283 and Guide D4687).This plan must include a worker health and safety sectionbe

20、cause 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 waste sites.7.1.2 Correct sampling procedures must be appl

21、ied 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 by atrained and experienced sampler because the various

22、 condi-tions 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 because of the possible variations in the material. Thesample

23、r 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 augering, chipping, or flaking sampling methodsmay fail a prime sampling requirement: that of randomselection of sample fractions. Parti

24、cles on the bottom or alongthe sides of the drum may consequently never have anopportunity to be included in a sample. Sample particles shouldbe selected by techniques that will minimize variation inmeasured characteristics between the available fractions andthe resulting sample (Practice C702).7.1.

25、5 The sampling equipment, sample preparationequipment, sample containers, etc. must be clean, dry, and inertto the 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 workingconditio

26、n. Visible contamination must be removed, and theequipment must be decontaminated with the appropriate rinsematerials. Decontaminated sampling equipment should beprotected from contamination. This may include, but not belimited to, storage in aluminum foil, plastic bags, polytetra-fluoroethylene (PT

27、FE) film, or other means of protection thatwill not impact the sample quality or intended analysis.7.2 Basic 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 th

28、e work zone.7.2.4 Inspect all drums to be sampled visually. Note anyabnormal conditions, including rust 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

29、 shall beinitiated. See Drum Handling Practices at Hazardous WasteSites for information on opening overpressurized 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 Ha

30、ndling Practices at Hazardous Waste Sites for furtherinformation on staging drums.7.2.5.1 Move the drums 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 detai

31、led inspection of individual drums.7.2.6.1 Record all relevant information from the drumlabels, markings, 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 li

32、d or loosenthe bung, allowing any pressure or vacuum to equalize.7.2.7.1 Precautionary Notes:(1) If the 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 equ

33、ipped with bungs, loosen the smallerbung first since doing so will make it easier to control therelease 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 e

34、vidence of a chemical reaction or suddenpressure buildup, the sampler should leave the area immedi-ately and evaluate whether remote drum opening equipmentshould be used.D5679 95a (2012)2(4) For flammable or explosive materials, the drum andsampling equipment should be grounded if the generation ofs

35、tatic electricity while opening or sampling the drum is apossibility. The drum 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 i

36、n which they are packed and shipped. The work planshould specify whether grounding 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 Dr
