The GHS-SDS Lifecycle for Authoring Professionals: Where Hazard Classification Begins

Friday, September 28 | 1:30 PM – 3:00 PM

Learning Level: Experienced | Topic: Hazard Communications

With adoption of GHS, OSHA has incorporated a highly complex characterization scheme into what was once a well-structured system of hazard communication. Given the ability to now employ “expert judgement” in the hazard classification process, OSHA’s “Letter of Interpretation” library is destined to swell all because authors can choose between ingredient profiles or use a final mixture approach. While the first offers simplicity and processing speed, the latter requires rigor and a host of analytical techniques. Both methods have advantages, but only the final mixture approach provides hazard inversion on a scientifically validated basis. This session intermingles GHS background with real-world examples of the hazard classification lifecycle. Attendees will not only gain insight into GHS flexibility, but will also acquire the tools needed to apply these practices.

Learning Objectives

  1. Understand the exemptions available for reclassification of products as a non-hazardous material.
  2. Identify how to derive an accurate estimate of weight percent and bioavailability for each hazardous component.
  3. Attain proficiency in determining process-specific analytical and sampling needs prior to initiating a release study and to shepherd samples through the laboratory.
