Select Projects

Copper GHS Technical Document:  Developed a technical background document detailing the scientific bases and rationale for hazard classifications for different forms of copper metal according to the GHS.  Evaluated and summarized existing scientific literature of human health and ecological health effects.  Prepared a public-facing communication tool that synthesized this information for the purposes of classifying the metal under GHS criteria.

Global Chemical Compliance Assistance:  Assisted global chemical compliance with evaluation of challenges of new jurisdictions, GHS assessment, and safety data for an automotive company.

Chemical Hazard Assessments:  Provided toxicological and ecological hazard assessment of chemicals for Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) compliance.  Identified and classified potential hazards according to the GHS.

Toxicity and Regulatory Substance Review:  For an anti-microbial substance under consideration for ban by the US Food and Drug Administration (US FDA), performed a comprehensive review of the regulatory landscape, hazard and risk conclusions of international authoritative and regulatory agencies, and available human health and ecotoxicity data.  Compiled the information into a dossier for potential external submission to regulatory agencies.

GreenScreen® Assessments:  Performed chemical hazard assessments for several chemicals using Clean Production Action’s GreenScreen® for Safer Chemicals method.

Sensitization Hazard Assessments:  Performed hazard assessments and quantitative risk assessments for the constituents of various consumer products designed to be in long-term contact with the skin.  Identified potential chemicals of concern and established exposure levels intended to protect consumers from experiencing adverse skin reactions.
