l
Ifworkersareexposedtoconcentrationsabovetheexposurelimit,theymustuse
appropriate,certifiedrespirators.Useaproperlyfitted,air  purifyingorair  fedrespirator
complyingwithanapprovedstandardifariskassessmentindicatesthisisnecessary.
Respiratorselectionmustbebasedonknownoranticipatedexposurelevels,the
hazardsoftheproductandthesafeworkinglimitsoftheselectedrespirator.
