Behaviorbasedsafetywhichgotitsstartinthe1970s,buthasgainedinpopularityinthe1990sisfoundedontheprinciplesandproceduresofaparticularsubdisciplineofpsychologycalledappliedbehavioranalysis.Behaviorbasedsafetyprogramsfocusoneffort(behavior)ratherthanresults(i.e.,numberofaccidents).Proponentsofbehavior-basedsafetybelievethatfocusingonsafeworkbehaviorsleadtoreductionofat-risk-behaviorsand,ultimatelyreducedaccidentsandinjuries.KrauseandRussell(1994)confirmthatriskybehavioriscommonlypresentinmostinjurysituationswherepeopleareinjured.Whenaninjuryrelatedtobehavioroccurs,itishighlylikelythatthissameattitudehasnotcausedinjurypreviously.Hence,riskybehaviormanifestedregularly,becomesapartofthesystem(commoncause).Therefore,itisthesecauseswhichmustbeidentified,moresothanthespecialones,because,oncefound,theydonotrequirereactions,suchasdisciplining,newregulations,etc.,butfundamentally,animprovementofthesystem.Behaviorbasedsafetyinterventionsarepeoplefocusedandareoftenbasedupononetooneorgroupobservationsofemployeesperformingroutineworktasks,feedbackonsafetyrelatedbehavior,coachingandmonitoring(Coxetal.,2004).Behaviorbasedsafetyprogramsconsistofemployeetrainingregardingsafeandat-riskbehaviors,systematicobservationsandrecordingoftargetedbehaviors,feedbacktoemployeesregardingthefrequencyandpercentageofsafeversusat-riskbehaviors,andincentivetoencouragetheobservationandfeedbackprocess.ThepioneeringworkofimprovingworkplacesafetyutilizingbehavioralapproachestosafetywasdonebyKomakietal.(1978).Theirstudyreportedthatbehavioralsafetyprogramsencouragedemployeestoactsafely.SimilarfindingswereechoedbystudiesofCooperetal.,1994,Krauseetal.,1999andCoxetal.,2004.
Coxetal.(2004)intheirstudywithinUKreactorplantsconfirmedthatbehavioralsafetyprovidedconsiderablevaluetostudytheorganizationasitsupportedculturalrealignmenttowardsa‘safetyfirst’culture.Cultureingeneral,andsafetycultureinparticular,isoftencharacterizedasanenduringaspectoftheorganization(CoxandCheyne,2000).OrganizationalsafetycultureasreportedbyCoxandCheyne(2000)composedof(i)anorganizationalattributewhichmanifestsinsafetypolicy,systemsandprocesses,structuresandreports,(ii)perceptionsoftheorganizationswhichmanifestinemployee,contractors,andexternalperceptions,and(iii)individualperceptionswhichmanifestinemployeescommitment,attitudes,responsibilityandbehaviors.
