Mr. Baril has over 40 years of experience in the field of environmental health, industrial hygiene, and safety management.  He has provided public and private sector organizations with comprehensive industrial hygiene and safety services such as OSHA compliance audits, safety management evaluation, hazardous substance exposure analysis, job hazard analysis, accident investigation and analysis, site remediation, and management and employee training. During his career, he has provided industrial hygiene and safety services to a diverse array of industries and employers that include healthcare, chemical plants, foundries, construction, power plants, heavy and light manufacturers, research laboratories, dry docks, waste water treatment plants, and commercial and residential real estate, to name a few.  In addition to working in the United States, he has provided industrial hygiene services in Argentina and Brazil.

Mr. Baril spent two years providing full time project management at “Ground Zero” directing environmental contaminant assessments, stabilization, and remediation of a large office building, adversely impacted by the destruction of the World Trade Center. This project incorporated multiple aspects within the industrial hygiene and safety spectrum, including: hazard assessments, hazard containment and isolation, mold removal, asbestos abatement, medical surveillance of site workers, respiratory protection, employee health and safety, etc.

Mr. Baril has developed and conducted various training programs and seminars for organizations such as the Business Council of New York State, Greater New York Safety Council, American Society for Healthcare Engineering (ASHE), Hospital Association of New York State (HANYS) and many others. Mr. Baril has conducted hundreds of lectures and training programs during his career. He has lectured extensively on such topics as asbestos, bloodborne pathogens, confined space entry, emergency response, fundamentals of industrial hygiene, hazard communication, health hazards in construction, hearing conservation and noise, indoor environmental quality, laboratory safety, lead and lead-based paint hazards, lock-out/tag-out, mold and moisture intrusion, office ergonomics, personal protective equipment strengths and limitations, respiratory protection, silica, tuberculosis, and ventilation.

For a large portion of his career, Mr. Baril has specialized in performing indoor environmental quality evaluations and mold and moisture intrusion investigations in hospital and commercial real estate settings. Gerard has conducted hundreds of indoor environmental quality investigations involving mold contamination, soil vapor intrusion, and contaminant infiltration. Subsequent to the performance of these evaluations, he has provided contractors with site-specific remediation work scopes and post-mold/water damage/water intrusion remediation criteria that must be met in order to permit re-occupancy and/or reconstruction of impacted occupancies

Mr. Baril also provides industrial hygiene litigation support services in the form of expert witness testimony, critical reviews, and technical oversight. Expert witness services have been provided for plaintiffs and defendants in mold/moisture intrusion, asbestos, silica, indoor environmental quality, perchloroethylene, and lead-based paint cases.

Mr. Baril has been actively involved in professional associations throughout his career, providing leadership on national committees and at local and regional levels to help shape policy and provide guidance on regulatory and emerging issues in the industrial hygiene and safety field.
