In our Forensic Engineering practice, we perform forensic analysis of traffic ac-cidents, premises accidents, and workplace accidents (industrial, commercial, drilling/mining, construction, etc.) - and accidents involving consumer prod-ucts, machinery, mechanical equipment and combustion equipment - and acci-dents involving contact with, and/or escape of, chemicals, gases or other haz-ardous materials. The analysis includes consideration of the relation of the acci-dent to financial damages, and to injury or death, whether from physical trauma or fire, explosion, or contact with chemicals, gases (e.g. carbon monoxide), or other hazardous materials. Our forensic engineering work includes accident analysis and reconstruction, and analysis of the safety of products, equipment, vehicles, roadways, surfaces, materials, residences, plants, factories, other faci-lities, etc. This work includes consideration of human factors and the actions of persons in accidents, and also, consideration of the design, machine guards, safeguards, warnings, and code and standards requirements for the products, equipment, materials, facilities, etc. involved in accidents.
In regard to the results of our work, we provide consultation, expert reports, affi-davits and testimony. Testimony has been provided in depositions, arbitrations, hearings, and in trials, including in Federal court and in State courts in Ohio, Pennsylvania, and in a number of other states from Kansas to Pennsylvania.
Investigations and inspections are a part of our Forensic Engineering work. This includes inspections of the sites of accidents, and also inspections of equip-ment, products, vehicles, roadways, surfaces, buildings, plants, factories, prop-erties, etc. involved in accidents, through hands-on inspections, and also through the study of photographic and video documentation of accident sites and equipment, etc., involved in accidents. The hands-on inspections augment (and are integrated with) the evidence otherwise documented for the accident. Also included in the investigations are investigations of processes, procedures and activities involved in accidents. Forensic Engineering Analysis and Accident Reconstruction has been performed, as appropriate, in the vicinity of the acci-dents, and also at our offices in the Akron and Cleveland, Ohio areas.
