Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe analysis and testing of solid waste requires collection of adequately sized, representativesamples. Wastes are found in various locations and physical s
3、tates. Therefore, each sampling routineshall be tailored to fit the waste and situation. Wastes often occur as nonhomogeneous mixtures instratified layers or as poorly mixed conglomerations. For example, wastes are commonly stored ordisposed of in surface impoundments with stratified or layered slud
4、ges covered by ponded wastewater.In these situations, the collector may be faced with sampling the wastewater, the sludge, and somedepth of soil beneath the sludges. Collecting representative samples in these situations requires acarefully assessed, well-planned, and well-executed sampling routine.1

United States14. Safety Plans4.1 Proper safety precautions shall always be observ
15、edwhen sampling wastes. Persons collecting samples shall beaware that the waste can be a strong sensitizer and corrosive,flammable, explosive, toxic, and capable of releasing ex-tremely poisonous gases. The background information ob-tained about the waste should be helpful in deciding the extentof s
16、afety precautions to be observed and in choosing protectiveequipment to be used. The information obtained should bechecked for hazardous properties against such references as“Saxs Dangerous Properties of Industrial Materials”4the“Hawleys Condensed Chemical Dictionary,”5and the “Toxicand Hazardous In
17、dustrial Chemicals Safety Manual for Han-dling and Disposal with Toxicity and Hazard Data.”6NOTE 1The following safety precautions are not comprehensive.Rather, they provide additional guidance on health and safety to comple-ment professional judgment and experience.4.2 Personnel should wear protect
18、ive equipment when re-sponse activities involve known or suspected atmosphericcontamination, vapors, gases, or airborne particulates may begenerated, or direct contact with skin-affecting substances mayoccur. Respirators can protect lungs, gastrointestinal tract, andeyes against air toxicants. Chemi
19、cal-resistant clothing canprotect the skin from contact with skin-destructive and-absorbable chemicals. Good personal hygiene limits or pre-vents ingestion of material.4.2.1 Equipment to protect the body against contact withknown or anticipated chemical hazards has been divided intofour categories a
20、ccording to the degree of protection afforded:4.2.1.1 Level AShould be worn when the highest level ofrespiratory, skin, and eye protection is needed.4.2.1.2 Level BShould be selected when the highest levelof respiratory protection is needed, but a lesser level of skinprotection. Level B protection i
21、s the minimum level recom-mended on initial site entries until the hazards have beenfurther defined by on-site studies and appropriate personnelprotection utilized.4.2.1.3 Level CShould be selected when the type(s) ofairborne substance(s) is (are) known, the concentrations(s) ismeasured, and the cri
22、teria for using air-purifying respirators aremet.4.2.1.4 Level DShould not be worn on any site withrespiratory or skin hazards. It is primarily a work uniformproviding minimal protection.4.2.2 The level of protection selected should be basedprimarily on the following:4.2.2.1 Type(s) and measured con
23、centration(s) of the chemi-cal substance(s) in the ambient atmosphere and its toxicity, and4.2.2.2 Potential or measured exposure to substances in air,splashes of liquids, or other direct contact with material as aresult of work being performed.4.2.2.3 In situations where the type(s) of chemical(s),
24、concentration(s), and possibilities of contact are not known, theappropriate level of protection shall be selected based onprofessional experience and judgment until the hazards can bebetter characterized.4.2.3 Level A ProtectionPersonnel Protective Equipment:(a) Pressure-demand, self-contained brea
25、thing apparatus,approved by the Mine Safety and Health Administration(MSHA) and National Institute of Occupational Safety andHealth (NIOSH),(b) Fully encapsulating chemical-resistant suit,(c) Coveralls,7(d) Long cotton underwear,7(e) Gloves (outer), chemical-resistant,(f) Gloves (inner), chemical-re

(De-pending on suit construction, worn over or under suit boot),(h) Hard hat7(under suit),(i) Disposable protective suit, gloves, and boots7(wornover fully encapsulating suit), and(j) Two-way radio communications (intrinsically safe).4.2.3.
27、1 The fully encapsulating suit provides the highestdegree of protection to skin, eyes, and respiratory system if thesuit material is resistant to the chemical(s) of concern duringthe time the suit is worn or at the measured or anticipatedconcentrations, or both. While Level A provides maximumprotect
28、ion, the suit material may be rapidly permeated andpenetrated by certain chemicals from extremely high airconcentrations, splashes, or immersion of boots or gloves inconcentrated liquids or sludges. These limitations should berecognized when specifying the type of chemical-resistantgarment. Whenever
29、 possible, the suit material should bematched with the substance it is used to protect against.4.2.3.2 Many toxic substances are difficult to detect ormeasure in the field. When such substances (especially thosereadily absorbed by or destructive to the skin) are known orsuspected to be present and p
30、ersonnel contact is unavoidable,Level A protection should be worn until more accurate infor-mation can be obtained.4.2.4 Level B ProtectionPersonnel Protective Equipment:4.2.4.1 Pressure-demand, self-contained breathing appara-tus (MSHA/NIOSH approved),4.2.4.2 Chemical-resistant clothing (overalls a

Therefore, a specialistshould select the most effective chemical-resistant clothing(and fully encapsulating suit) based on the known or antici-pated hazards or job function, or both.4.2.4.11 For initial site entry and re
36、connaissance at an opensite, approaching whenever possible from the upwinddirection, Level B protection (with good quality, hooded,chemical-resistant clothing) should protect response personnel,providing the conditions described in selecting Level A areknown or judged to be absent.4.2.5 Level C Prot

43、er decontamination steps are taken. Samplingpersonnel should be trained in safety aspects of hazardouswaste sampling.4.4 Testing air emission for determining the vapor/gasconcentrations can be accomplished through the use of aportable organic vapor analyzer. The probe should be held 1 to2 in. (2.5 t
44、o 5 cm) above the sampling point. Follow manufac-turers operating instructions for proper calibration, use, andcare.5. Sampling Plans5.1 A sampling plan is a scheme or design to locatesampling points so that suitable representative samples descrip-tive of the waste body can be obtained. Development
45、ofsampling plans requires the following:5.1.1 Review of background information about the wasteand site.5.1.2 Knowledge of the waste location and situation.5.1.3 Decisions as to the types of samples needed.5.1.4 Decisions as to the sampling design required.5.2 Background data on the waste is extremel
46、y helpful inpreassessment of the wastes composition, hazards, and extent.(See Notes 2 and 3.)NOTE 2If, after researching the available background information theuser cannot obtain from the material enough information about the wasteto determine the probable composition and probable hazards, then the
47、 usershould use other procedures. Such situations are beyond the scope of thisguide.NOTE 3The background information is needed to determine necessarysafety equipment, safety procedures, sampling equipment and samplingdesign, and procedures to be used.5.2.1 Possible sources of information on the site
48、 and wasteinclude the following:5.2.1.1 File searches of state and local records includingwaste manifests, waste approvals, and land permit applications.5.2.1.2 File searches of generator records (if the generatorcan be identified) including chemical analyses, safety datasheets, design drawings, and
49、 manufacturing process informa-tion.5.2.1.3 File searches of treatment, storage, disposal, andtransport facilities. Records involved with handling the waste.5.2.1.4 Researching published data concerning the site suchas scientific journal articles, EPA publications, and newspaperstories. Newspapers are the most likely source, but the infor-mation is seldom very technical.5.2.1.5 Interviews of key people such as past and presentemployees of the site or generator, state and local officials,residents of the area, and so forth.5.2.1.6 Aerial photographs provide a histor
