1、Designation: E 2255 04Standard Practice forConducting Visual Assessments for Lead Hazards inBuildings1This standard is issued under the fixed designation E 2255; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi

2、sion. 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 describes procedures for conducting visualassessments in buildings to visually identify the type andlocation of

3、potential lead hazards. These potential hazards areassociated with deteriorated leaded paint, lead in dust, or leadin soil.1.2 This practices addresses visual assessment proceduresfor four lead-hazard activities: lead risk (hazard) assessment (E2115), clearance examination (E 2271), assessment of pa

4、intcondition, and re-evaluation inspection.1.3 Because there is considerable overlap among the re-quirements for these four types of lead-hazard activities, thisstandard first describes a generic visual assessment procedure,and then defines a specific procedure for each assessment typein terms of ad

5、ditions to, or deletions from, the genericprocedure.1.4 This practice does not address testing needed to confirmthe presence of lead hazards.1.5 This practice contains notes, which are explanatory andare not part of the mandatory requirements of this standard.1.6 This standard does not purport to ad

6、dress 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.

Consult Practice E 1864 for information regarding aquality system for field activities and consult Guide E

17、 2052 forguidance in managing lead hazards.4.3 This practice is intended for use by individuals trainedto conduct visual assessments associated with lead-hazardactivities and in reporting their results. This practice is alsoapplicable for use by others interested in visual assessment ofproperties fo

18、r lead hazards, such as building code officials,homeowners, and insurers.5. Requirements for Individuals Conducting VisualAssessments5.1 Persons conducting visual assessments need a range ofexpertise, including the ability to identify the type, extent, andcause of coating deterioration and component

19、 deterioration,and to determine the presence of surface dust, debris, and baresoil. Users of visual assessment services should review theircredentials and experience to determine whether they arequalified to conduct the work.5.1.1 Visual assessments conducted as part of a lead-basedpaint activity wi

20、thin the scope of regulations promulgated byauthorities having jurisdiction shall be conducted by appropri-ately certified or licensed individuals.6. Materials and Supplies6.1 Copies of Forms, (see Appendix X1).6.2 Clipboard, for holding forms.6.3 Pencil And Sharpener.6.4 Indelible Ink Pen or Perman

21、ent Marker.6.5 Flashlight, or other self powered portable light source,as needed, for making visual observations in low light levelareas.6.6 Camera (optional), with supporting equipment neededto create photographs that can be labeled.7. Procedure for Conducting the Generic VisualAssessment7.1 Genera

22、l Visual Assessment RequirementsThe follow-ing requirements apply to the conduct of visual assessments:7.1.1 Reporting:7.1.1.1 Use a recording system that uniquely identifies thetype and location of each hazard and each incidence of buildingcomponent deterioration. At a minimum, the recording system

23、must allow a reasonably educated person, when provided withall the records generated from a visual assessment, to deter-mine what hazards and incidences of building componentdeterioration were identified and where each was found. Thispractice provides the individual conducting the visual assess-ment

24、 with the flexibility to use personal choices for somerecording needs.7.1.1.2 Examples of forms (site plans, building facesketches, floor plans, building component condition, paint/dust/debris, and grounds) for recording information are shownin Appendix X1. An example of using these forms is present

25、edin Appendix X2.7.1.1.3 Alternate forms are acceptable provided that theyallow unique identification of all hazards and incidences ofbuilding component deterioration.7.1.1.4 Information recorded on any particular form can belimited to only those areas where potential hazards are found.The example f

26、loor-plan shown in Appendix X2 includes detailfor the living room, dining room and porch only becausepotential hazards were not identified in other rooms. However,the individuals conducting visual assessments are cautionedagainst overly sparse records when no potential hazards arefound. Lack of reco

27、rds may be viewed as a potential indicatorthat portions of the assessed area were not inspected.7.1.1.5 Use of a camera to photographically capture thestructures and grounds included within the boundaries of theassessment area provides a means of complementing forms.7.1.2 Symbols and CodesUse of sym

28、bols and codes is notrequired but is recommended to reduce the effort needed torecord building and grounds locations and observations ofhazards and component deterioration. The symbols and codes,if used, shall be sufficiently defined to identify the items towhich they refer. The codes provided in va

29、rious sections of thisstandard, such as in Tables 1-3, are exemplary; others may beused depending on the needs of the person conducting thevisual assessment.7.2 Existing InformationReview historic lead-hazardevaluation, hazard reduction and clearance reports and otherinformation describing ongoing m

30、aintenance activities, andrelevant building operations to identify changes from previousconditions and locations of renovation, remodeling, construc-tion or abatement activity. Use this review to help define theboundaries of the assessment area.7.3 Multifamily HousingUnits to be assessed shall bedet

31、ermined using appropriate statistical procedures.7.4 Boundaries of Area to Be AssessedIn consultationwith the client requesting the visual assessment, determine theboundaries of the area to be assessed.7.5 Walk-ThroughWalk through the area to be assessed tobecome familiar with the site and verify th

32、e boundaries of thearea to be assessed, if the entire structure is not to be assessed.Portions of the property excluded from the visual assessmentshall be documented and reported.7.6 Component ReplacementIn consultation with the cli-ent requesting the visual assessment, determine whether anywindows

33、or doors penetrating the exterior walls in the assess-ment area have been replaced. In cases where such a windowor door has been replaced, the visual assessment shall includeboth the interior and exterior of the adjacent walls. In addition,the assessment shall include any horizontal surfaces and the

34、ground beneath the replaced windows or doors.7.7 Access to Area to Be AssessedDetermine whether allareas and surfaces to be assessed are accessible and whethermovable building components such as windows and doors inthe areas to be assessed are functional. Resolve, to the extentpossible, problems and

35、 questions associated with access toassessment areas and functionality prior to conducting thevisual assessment. Record incidences of unresolved accessissues and lack of functionality that inhibit the ability to makea visual assessment of those areas or components.E22550427.7.1 Site-Safety Condition

36、sDuring the walkthrough in-spection, identify potential problems associated with sitesafety. Resolve, to the extent possible, such problems that mayimpact the assessment. Record incidences of potential site-safety conditions.7.8 Site-Plan:7.8.1 If the area to be assessed includes any exteriorportion

37、s of a unit or structure, prepare a site-plan for use inrecording findings (see the Site-Plan Form in Appendix X1).7.8.1.1 If a pencil is used for sketching the Site-Plan Form,make the sketch permanent by overwriting it with an indeliblemarker.7.8.2 Show on the Site Plan:7.8.2.1 The relative positio

38、n and shape of the buildings onthe property being assessed and designate the primary structureundergoing visual assessment (see Note 1).TABLE 1 Description of Paint ConditionHazard Hazard Code Description Observed ConditionADeteriorated Paint or OtherCoatingspaint Deteriorated conditions include pai

39、nt or othercoatings that are chalking, checking, cracking, orflaking. Incidental blemishes in painted surfacesdue to factors such as nail holes without crackingof surrounding paint, and so forth, should not bedesignated as deteriorated paint.Note the condition of paint deterioration as follows: $2m2
