Select Projects

Worker and Consumer Risk Assessment:  Evaluated potential health risks for production workers and consumers related to a plasticizer found in decorative films used during product assembly.  Reviewed employee activity patterns related to installing the part, chemical-specific properties related to exposure and reproductive toxicity study data in animals for the chemical of interest and structural analogs.

Leather Product Alternatives Assessment:  Evaluated potential alternatives to an antimicrobial chemical used in the production of leather that has significant skin sensitization potential.  Conducted a literature review to identify feasible alternatives from the context of chemical hazard, availability, cost and performance.

Latex Residue Assessment:  Identified an appropriate analytical testing strategy to confirm the presence of allergenic latex residue on a consumer product and assessed the risk of potential skin sensitization associated with expected consumer-level exposures.  The evaluation helped the manufacturing company reach a decision about product safety.

Evaluation of Automotive Refrigerants:  Conducted a risk assessment of two alternative chemicals proposed for use in vehicle air conditioning systems.  Fault tree analysis (FTA) was used to estimate risks for vehicle occupants and repair personnel in the context of several different vehicle failure events (e.g., collisions and fires).

Alternatives Evaluation of Two Dielectric Fluids:  Evaluated the relative risks posed by the use of acetonitrile or propylene glycol as a dielectric fluid in an electrical component of a consumer product.  Considered exposures of consumers, assembly workers, and repair personnel in the event of product failure or damage.

Evaluation of Potential Allergenicity of Ingredients in a Medical Product:  Assessed the ingredients contained in a medical diagnostic gel to determine their potential to produce skin sensitization or dermal irritation.

Risk Evaluation of Fungicides in Children’s Art Paint:  Evaluated the potential health implications of a fungicidal contaminant in an art paint material.  A rapid (24-hour) assessment was conducted and used by the client to decide on the need for a product recall.
