FOREWORD
This Indian StandardwasadoptedbytheBureauofIndianStandards,afterthedraftfinalized bytheOccupational
SafetyandHealthandChemicalHazardsSectional CommitteehadbeenapprovedbytheChemical DivisionCouncil.
Highvisibility warningclotheisoneofthepersonnelprotectiveequipmentworn asameans toprovidevisualsignal
ofthe wearer's presenceand intendedtoprovide conspicuityofthe wearerunder any light conditionsbydayand
under illumination byvehicleheadlights inthedark.Conspicuityisenhanced by increasingthecontrastbetween
theclothinganditsambientbackgroundorsurroundings.Classesofvisibilityhazardsareidentified andappropriate
markings for the clothing are suggested based on worker risk hazards,such as complex backgrounds, vehicular
traffic density and speeds.
Two different colours for background and combined performance materials are defined, providing options for
increasing wearer's conspicuity against most backgrounds found in urban and rural work environments.Users
shouldconsidertheprevailingambientbackgroundinwhich protectionisrequiredandselectthecolourproviding
thepreferredcontrast.
Higherphotometricperformancelevelsofretroretlectivematerialprovidegreatercontrastandvisibilityoverwider
viewing anglesofsafetyclothingwhen seen inheadlightsduringdarkness. When greaterconspicuityisrequired,
thehigher performancelevelofretroreflective material should be used.
