California Proposition 65 Labeling Workshop

PDF Brochure — offered September 28, 2015

Course Description and Objectives

The goal of this workshop course is to provide a detailed understanding of the labeling obligations under California Proposition 65.  Emphasis will be placed on the risk-based requirements of California Proposition 65.  The course will provide ample time for working on examples relating to determining the need for California Proposition 65 labeling and for participant discussion of California Proposition 65-related issues.

This is considered to be an advanced course. While there are no formal prerequisites for this course, it is strongly recommended that participants have a working knowledge of MSDS and labels and that they have either taken the SCHC courses Toxicology for Hazard Communication and Hazard Determination and Risk Assessments or that they are comfortable with the basic principles of toxicology and risk assessment.

Intended Audience

Hazard communication professionals looking to improve their California Proposition 65 labeling skills.
