Summary of Guid

21、e4.1 This guide describes the criteria, practices, and recom-mendations for the physical resources, data validation, andmode of operation of the laboratory.5. Significance and Use5.1 Data on the composition and characteristics of environ-mental atmospheres, such as ambient or work space air, arefreq

22、uently used to evaluate the health and safety of humans.Data on the composition of atmospheric deposition samples areoften used for environmental impact assessment.5.2 These data are frequently used to ascertain compliancewith regulatory statutes that place limits on acceptable com-positions and cha

23、racteristics of these atmospheres.5.3 Laboratories that produce environmental sampling andanalysis data and those who have the responsibility of selectinga laboratory to perform air quality studies need to know whatcriteria, practices, and recommendations have been acceptedby consensus within this f

24、ield of endeavor.5.4 Demonstration and documentation by a laboratory thatthere is judicious selection and control of organizationalfactors, facilities, resources, and operations enhance the reli-ability of the data produced and promote the acceptance ofthese data.6. Responsibilities and Duties of th

25、e Laboratory6.1 The purpose of the laboratory is to provide informationthat is factual, accurate, reliable, and adequate for its purpose.The procedure by which this is to be achieved is by theeffective administration of a quality assurance (QA) plan by themanagement of the organization. The elements

26、 of a qualityassurance plan are described in 6.1.1-6.1.6.1.6.1.1 OrganizationA table of organization which indi-cates the organizational structure and the lines of authority,areas of responsibility, and job descriptions should be avail-able. Key personnel, including their workplace locations andphon

27、e numbers, should be identified for each organizationalentity. Separate organizational charts for subcontractors mightalso be needed. QA managers should be identified along withtheir relationships to other project personnel. The QA manag-ers should be organizationally independent of project manage-m

28、ent so that the risk of conflict of interest is minimized.6.1.1.1 Human ResourcesThe key personnel of the orga-nization should be described by means of personal rsumspresenting the applicable education and work experiencerelative to his or her position in the table of organization andthe requirement

29、s of that position.6.1.1.2 Physical ResourcesThe laboratory facilitiesshould provide a working environment that is clean, air-conditioned, heated, well-lighted, and safe. The instrumenta-tion and equipment should be appropriate to the operationalneeds of the laboratory.6.1.2 MethodologyWritten proce

30、dures should be readilyavailable to all personnel.6.1.2.1 Sample collection and handling procedures, andstorage requirements should be written.6.1.2.2 Calibration and standardization procedures shouldbe written.6.1.2.3 Standard Operating Procedures (SOPs) and analyti-cal methods should be written.6.

31、1.2.4 There should be a document control system to assurethat the written procedures are current and complete.6.1.2.5 All of the above should be periodically subjected toperformance and system audits.6.1.3 Metrology SystemsAll systems for making measure-ments should have the following features:6.1.3

32、.1 Calibration and standardization procedures, includ-ing a description of a procedure for establishing traceability,description of calibration standards, and a schedule for cali-bration,6.1.3.2 Preventative maintenance procedures including aschedule for maintenance intervals and documentation of th

33、eirproper completion, and6.1.3.3 Records of modification of configuration that mayoccur in any measurement system due to repair and servicingof equipment, replacement of components or reagents, orchange of procedures.6.1.4 Data RecordingThe laboratory should keep recordsof submitted samples and comp

34、leted analyses in a manner thatprovides for the retrievability, preservation and traceability ofD3614072the sample source, the procedures used, and the person orpersons responsible for the sampling and analysis.6.1.4.1 All laboratory data sheets should be dated andsigned by the analyst.6.1.4.2 A pol

35、icy for the use of computers for data acquisi-tion, archiving, and mathematical calculations should be imple-mented.6.1.5 Data ValidationThe laboratory should keep recordsof analytical performance by means of audit procedures,reference sample programs, and interlaboratory tests. Whereapplicable, qua

36、lity control charts should be used to reportresults from these validation activities. Quality control proce-dures found in most current methods should be followed. (1)36.1.6 Deficiency CorrectionThe organizational systemshould provide the authority and the responsibility for adesignated person or pe

37、rsons to investigate out of controlprocedures and to inform the laboratory management of theproblems that occur. This is often the responsibility of the QAmanager.6.1.6.1 A current log should be maintained of such deficien-cies and the action taken to correct them.7. Organization7.1 The production o

38、f reliable data is dependent upon theconscientious effort of everyone who has any involvement withthe service. Therefore, it is important that each member of theorganization have a clear-cut understanding of his or her dutiesand responsibilities, and their relationship to the total effort.The manage

39、ment of the laboratory has a prime responsibility indefining the policy goals in relation to the quality of perfor-mance and assigning the specific areas of responsibility to theindividual. The human resources that are required for theoperation of the laboratory will vary with the specific functions

40、that are to be served, but the minimum personnel and theirqualifications should generally be as follows:7.2 Human Resources (2)7.2.1 The DirectorThe laboratory director should be afull-time employee of the organization that operates the labo-ratory. He or she should have a minimum of an earnedbaccal

41、aureate degree in science or engineering from an accred-ited college or university or the equivalent (see Note 1) with aminimum of 5 years experience in sampling and analysis ofatmospheres or in a related field.
