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.
Setup
Create hazard categories (phrase families)Define phrases for each categoryAssign phrase severitiesCreate subformat for HE documentCreate / Promote component(s)Assign hazard categories to component(s)Finding / Basis / Source for each categoryUse components in substances or mixtures
Setup - Health Hazard Categories
Eye Contact
Skin Contact
Ingestion
Skin Absorption
Inhalation
Signs & Symptoms
Target Organ Toxicity
Carcinogenicity
Reproductive Toxicity
Mutagenicity
Setup - Define phrases for categories
Setup - Assign Phrase Severities
Setup - Create HE Subformat
Setup - Create / Promote Component(s)
Setup - Assign Hazard Categories (PTXT)
Setup - Assign Hazard Categories (CTXT)
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.)
Setup - Review
PTXT (product level)
CTXT (component level)
Use evaluated components in substances or mixtures

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.
ProductInfo
Not an actual product… Demonstration purposes only.
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.
MSDS / HE Comparison
MSDS
HE
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
