1、Designation: E2271 05a (Reapproved 2012)1Standard Practice forClearance Examinations Following Lead Hazard ReductionActivities in Dwellings, and in Other Child-OccupiedFacilities1This standard is issued under the fixed designation E2271; the number immediately following the designation indicates the

2、 year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEFootnotes corrected editorially in April 2012.1. Scope1.1

3、This practice covers visual assessment for the presenceof deteriorated paint, surface dust, painted debris, and paintchips with environmental sampling of surface dust to deter-mine whether a lead hazard exists at the time of samplecollection, following lead-hazard reduction activities, or otherbuild

4、ing maintenance and modification activities.1.2 This practice addresses 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 practi

5、ce also addresses clearance examinations thatmay include soil sampling, 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-quent

6、ly whether a clearance area, passes or fails a clearanceexamination.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

7、 values stated in SI units are to be regarded asstandard. The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.6 This standard does not purport to address all of thesafety concerns, if any, associate

8、d 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.

20、ficance 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 units, common areas or exterior sites, and c

21、hild-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 conduct of a clearance examination. Ata minimu

22、m, 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 PracticeE2255 and the record keeping requir

23、ements are found inPractice E2239.4.4 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 the individualconducting the clearance exa

24、mination.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 and financial professionals, insurance orga

25、-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.

37、mily dwellings or groups of other detached dwellings may be permittedin regulations promulgated by authorities having jurisdiction. For ex-ample, in the United States, see 40 CFR 745.227(e)(9) and 24 CFR35.1340(b)(2) or other regulations promulgated by authorities havingjurisdiction. Regulations can
