Creating Hazard Evaluations with The Wercs

1. Creating Hazard Evaluations with The Wercs Kathy Morrow

2. Background Information • Setup Information • Evaluating Mixtures • MSDS / HE Comparison • Benefits • Hazard Evaluation (HE) Example • Questions

3. Background Information • OSHA requires that companies evaluate the hazards of their products. • Hazards need to be communicated to employees and downstream users (via the MSDS). • ConocoPhillips wanted to create a publishable hazard evaluation document summarizing the results of the evaluation.

4. Setup • Create hazard categories (phrase families) • Define phrases for each category • Assign phrase severities • Create subformat for HE document • Create / Promote component(s) • Assign hazard categories to component(s) • Finding / Basis / Source for each category • Use components in substances or mixtures

5. Eye Contact Skin Contact Ingestion Skin Absorption Inhalation Signs & Symptoms Target Organ Toxicity Carcinogenicity Reproductive Toxicity Mutagenicity Setup - Health Hazard Categories

6. Setup - Define phrases for categories

7. Setup - Assign Phrase Severities

8. Setup - Create HE Subformat

9. Setup - Create / Promote Component(s)

10. Setup - Assign Hazard Categories (PTXT)

11. Setup - Assign Hazard Categories (CTXT)

12. Setup - Information for each category • Finding – the severity or weight of evidence assigned to the hazard (e.g. mild irritant, highly toxic, limited evidence of kidney damage, inadequate evidence of carcinogenicity, etc.) • Basis – the scientific or other basis for the assigned finding (e.g. irritation scores, LD50 values, study observations, human experience, etc.) • Source – the source of the information cited as the basis for the finding (e.g. literature review, journal article, textbook chapter, MSDS, etc.)

13. PTXT (product level) CTXT (component level) Setup - Review

14. Setup - Complete • Create hazard categories (phrase families) • Define phrases for each category • Assign phrase severities • Create subformat for HE document • Create / Promote component(s) • Assign hazard categories to component(s) • Finding / Basis / Source for each category Use evaluated components in substances or mixtures

15. ProductInfo Not an actual product… Demonstration purposes only. Evaluating Mixtures ComponentInfo Wercs Autogenerate is used to quickly populate the category of a mixture, using the severity levels assigned to each of the phrases in each of the hazard categories for each component.

16. Evaluating Mixtures Not an actual product… Demonstration purposes only. Professional judgment may warrant modifying the product category depending on the percentages of the individual components and/or known toxicity of the product itself. Reasoning for the modification would be entered into the Basis and/or Source fields.

17. MSDS / HE Comparison MSDS HE

18. Benefits • Provides a separate subformat for toxicologists to conduct hazard evaluations in The Wercs • MSDS Authors can quickly estimate the hazards of mixtures • Hazards identified in the Hazard Evaluation populate various sections of the MSDS • Categories for the mixture are easily reviewed by an MSDS Author prior to running rules • Hazard Evaluation can be published and used as documentation for hazards on MSDS
