Hazardous Materials

A hazardous materials expert witness typically has extensive experience in industrial health, environmental health, chemical engineering, environmental engineering, construction safety, and/or is a certified industrial hygienist.

Hazardous materials (hazmat) are dangerous goods that pose a risk even when not being transported, and are subject to chemical regulations from organizations such as the Pipeline and Hazardous Materials Safety Administration (PHMSA), the Federal Motor Carrier Safety Administration (FMCSA), and the U.S. General Services Administration (GSA).

Expert witness service by a hazardous substance expert could include expert testimony in toxic tort litigation cases, insurance disputes, or an accident investigation. Litigation support services by a hazardous materials specialist could include exposure assessment, toxicology report review, expert opinion, expert reports, and expert witness testimony at a trial. A law firm may request a qualified expert with prior testifying experience in a high-profile case or litigation involving a significant financial stake. In addition, lead counsel may seek a hazardous material subject matter expert for pre-litigation consulting work.

Whether the case involves OSHA compliance, indoor air quality, exposure to hazardous material or hazardous waste, industrial hygiene, or other safety issues, Cahn Litigation Services has the experience required to turn an expert witness search around quickly. The firm routinely provides expert witnesses with the right balance of expertise and testimony to support each unique project.
