1、Designation: E 2271 05aStandard Practice forClearance Examinations Following Lead Hazard ReductionActivities in Dwellings, and in Other Child-OccupiedFacilities1This standard is issued under the fixed designation E 2271; the number immediately following the designation indicates the year oforiginal

2、adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers visual assessment for the presenceof deteriora

4、sses clearance examination of single-family detached dwellings (including exterior structures, suchas fences), multifamily dwellings having similar units, com-mon areas or exterior sites, and child-occupied facilities.1.3 This practice also addresses clearance examinations thatmay include soil sampl

5、ing, for example when soil abatementhas been performed.1.4 This practice includes a procedure for determiningwhether regulatory requirements for lead clearance levels fordust and, where warranted, soil have been met, and, conse-quently whether a clearance area, passes or fails a clearanceexamination

6、.NOTE 1This practice is based on that portion of “clearance” describedin 40 CFR Part 745 for abatement, and in 24 CFR 35 for lead-hazardreduction activities other than abatement, except that composite dustsampling is not used.1.5 The values stated in SI units are to be regarded as thestandard.1.6 Th

7、is standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

18、 room, or room equivalent, or(2) portions of multiple rooms, multiple rooms or roomequivalents, depending upon the extent or location, or both, ofthe lead hazard control activity. The exterior work space mayinclude (1) a portion of a building faade, an entire buildingfaade, associated structures, su

Significance and Use4.1 A clearance examination of abatement areas and otherareas associated with other lead-hazard control activities, orbuilding maintenance or modification activities in single-family detached dwellings, multifamily dwellings having simi-lar unit

20、s, common areas or exterior sites, and child-occupiedfacilities is performed to determine that the clearance area isadequately safe for reoccupancy.4.2 It is the responsibility of the user of this standard toassure that all regulatory, contractual, and personnel require-ments are met prior to conduc

21、t of a clearance examination. Ata minimum, users of this standard shall be trained in its use andin safe practices for its conduct.4.3 This practice is one of a set of standards developed forlead hazard management activities. The visual assessmentprocedures required in this standard are found in Pra

22、cticeE 2255 and the record keeping requirements are found inPractice E 2239.4.4 Although this practice was primarily developed fordwellings and for other child-occupied facilities, this practicemay be also applied to nonresidential buildings and relatedstructures by agreement between the client and

23、the individualconducting the clearance examination.4.5 This practice may be used by owners and propertymanagers, including owner-occupants, and others responsiblefor maintaining facilities. It may also be used by lead hazardmanagement consultants, construction contractors, laborgroups, real estate a

24、nd financial professionals, insurance orga-nizations, legislators, regulators, and legal professionals.4.6 This standard does not address whether lead-hazardreduction activities or other building modification or mainte-nance work were done properly.5. General Requirements5.1 Applicable RegulationsTh

25、e clearance examinationshall be conducted in accordance with all regulations promul-gated by authorities having jurisdiction. Applicable regulationsare those that are currently in force in jurisdictions where theclearance examination is conducted.5.2 Personnel QualificationsAll persons conducting or

26、participating in the clearance examination shall be qualified inaccordance with regulations promulgated by authorities havingjurisdiction.NOTE 2For example, in the United States, 40 CFR Part 745 SubpartLor24 CFR Part 35 Subpart R, or both, may apply.5.3 Reporting ScheduleBefore arriving at the prope

27、rty,determine with the client the schedule for reporting the resultsof the clearance examination. Specify in hours or days whenthe clearance summary and clearance report are due to theclient. Consider in the reporting schedule the following: whenthe last sample for the clearance examination is to be

28、 collected;when the results of testing are to be available; and, whether andhow reoccupancy, additional construction, or maintenancework, or other factors affect the schedule.5.4 Dust Wipe Sampling MaterialsUse only dust wipesthat meet Specification E 1792 to collect samples of surfacedust.5.5 Dust

29、Sampling ProcedureCollect surface dust wipesamples in accordance with Practice E 1728. Record the uniquelocation description, unique sample identifier, the dimensionsof the area sampled, and all other sample collection informa-tion on the Paint/Dust/Debris Data Form (given in PracticeE 2255).5.6 Soi

30、l Sampling ProcedureWhen required, collect soilsamples in accordance with Practice E 1727. Record the uniquelocation description, unique sample identifier, and all othersample collection information on the Ground Data Form (givenin Practice E 2255).5.7 Laboratory Selection:5.7.1 Use only laboratorie

31、s (either fixed site or field opera-tional) that hold the necessary accreditations, certifications, andrecognitions needed to conduct lead testing services requiredby regulations promulgated by authorities having jurisdiction.NOTE 3For example, in the United States ofAmerica, laboratories arerecogni
