Designation:E137014Standard Guide forAir Sampling Strategies for Worker and WorkplaceProtection1This standard is issued under the fixed designation E1370;the number immediately following the designation indicates the 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.1.Scope1.1 This guide describes criteria to be used in defining airsampling strategies for workplace health and safety monitoringor evaluation.Sampling criteria such as duration,frequency,number,location,method,equipment,and timing are allconsidered.1.2 Where air sampling is prescribed by law or regulation,this guide is not intended to take the place of any requirementsthat may be specified in such law or regulation.1.3 Guidance for surface sampling strategies for metals andmetalloids is provided in Guide D7659.1.4 This 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.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD4840 Guide for Sample Chain-of-Custody ProceduresD7659 Guide for Strategies for Surface Sampling of Metalsand Metalloids for Worker ProtectionE1542 Terminology Relating to Occupational Health andSafety2.2 ISO Standards:3ISO 7708 Particle Size Fraction Definitions for Health-Related SamplingISO/IEC 17025 General Requirements for the Competenceof Testing and Calibration LaboratoriesEN 1540 Workplace ExposureTerminology3.Terminology3.1 For definitions of terms relating to occupational healthand safety,see Terminology E1542.3.2 For definitions of terms relating to atmospheric sam-pling and analysis,see Terminology D1356.3.3 Definitions:3.3.1 alarm samplersampling device that produces analarm(audible,visible,or both)when the concentration of asubstance exceeds a pre-set value.3.3.2 exposure(by inhalation)situation in which a chemi-cal or biological agent is present in the air that is inhaled by aperson.EN 15403.3.3 occupational exposure limitupper bound on theacceptable concentration of a hazardous substance in work-place air.3.3.3.1 DiscussionTypically established by national au-thorities in efforts to protect workers health.3.3.4 professional judgmentapplication and appropriateuse of knowledge gained from formal education,experience,experimentation,inference,and analogy.D76593.3.4.1 DiscussionThe capacity of an experienced profes-sional to draw correct inferences from incomplete quantitativedata,frequently on the basis of observations,analogy,andintuition.3.3.5 sampling excursionduration of time during whichactive sampling is not being performed,typically between twodurations of active sampling.4.Significance and Use4.1 This guide describes standard approaches used to for-mulate air sampling strategies before actual air samplingoccurs.4.2 For most workplace air sampling purposes,and for themajority of materials sampled,air sampling strategies arematters of choice.Air sampling in the workplace may be donefor single or multiple purposes,such as health impact,hazardor risk assessment,compliance assessment,or investigation of1This guide is under the jurisdiction of ASTM Committee D22 on AirQualityand is the direct responsibility of Subcommittee D22.04 on Workplace AirQuality.Current edition approved April 1,2014.Published May 2014.Originallyapproved in 1990.Last previous edition approved in 2008 as E1370 96(2008).DOI:10.1520/E1370-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from International Organization for Standardization(ISO),1,ch.dela Voie-Creuse,CP 56,CH-1211 Geneva 20,Switzerland,http:/www.iso.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 complaints.Problems can arise when a single air samplingstrategy is expected to satisfy multiple diverse purposes.4.2.1 Proper consideration of limitations of cost,space,power requirements,equipment,analytical methods,trainingand personnel result in a best available strategy for eachpurpose.4.2.2 A strategy designed to satisfy multiple purposes mustbe a compromise among several alternatives,and will not beoptimum for any one purpose;however,the strategy should beappropriate for the intended purpose(s).4.2.3 The purpose or purposes for sampling should beexplicitly stated before a sampling strategy is selected in orderto ensure that the sampling strategy is appropriate for theintended use.Good sampling practice,legal requirements,costof the sampling program,and the utility of the
