    TEXT VERSION OF SLIDE:

    Title: Maximum Use Concentration (MUC)
    Type: Text Slide
    Content:

    • Must select a respirator that maintains exposure to the hazardous substance, when measured outside the respirator, at or below the MUC
    • Must not apply MUCs to conditions that are IDLH; instead must use respirators listed for IDLH conditions per paragraph (d)(2)
    • When the calculated MUC exceeds the IDLH level for a hazardous substance, or the performance limits of the cartridge or canister, then employers must set the maximum MUC at that lower limit
    • Must select a respirator appropriate for the chemical state and physical form of the contaminant
