Notations: How are They Assigned and How Should They be Used in Industrial Hygiene Practice? - ON-DEMAND WEBINAR


Electronic (digital download/no shipping)

Member - $99.00
NonMember - $205.00


This webinar focuses on the Notations recommended by the Threshold Limit Values for Chemical Substances (TLV®-CS) Committee. The purpose of Notations is to highlight toxicity endpoints that set certain chemical substances apart and to alert the practicing industrial hygienist that special considerations need to be given to these materials to ensure adequate protection of workers. The intent of the webinar is to give attendees an improved understanding of Skin, DSEN, RSEN, OTO, and IFV notations and the ACGIH® Carcinogen Classifications and how they can be used to optimize their exposure control programs. The webinar will be comprised of: (1) a brief overview; (2) discussion of the purpose of special notations; (3) description of how each notation was derived, including description of the types of background information, data and specific criteria used; and (4) discussion of how to use notations in the application and interpretation of TLVs®. “Real-world” examples will be used throughout the webinar to illustrate how the various notations are assigned and how these should be interpreted and applied by the practicing industrial hygienist.

  • Understand the basis for Notations in general and each individually
