After graduating, Ms. Hess-Kosa became the thirteenth member and first female industrial hygiene consultant for Firemen’s Fund Insurance Companies in San Francisco, California. In 1983, Ms. Hess-Kosa tested for and passed the national AIHA certification exam, earned her designation as a Certified Industrial Hygienist. During her five years, she had the opportunity in addition to traditional industrial hygiene consulting to become involved in a variety of unique environ¬mental problems, including indoor air quality concerns in an 800-occupant of¬fice building, information gathering for performing environmental site as¬sessments, and waste management. In 1984, she returned to Texas and started her own private consulting firm which, after several name changes, is now Omega Environmental Consulting, Inc.
As a conventional industrial hygienist, Ms. Hess-Kosa evaluated hazardous substance and noise exposures to workers in industrial environments ranging from sawmills to foundries in both large and small operations. She has also assessed exposures to office occupants regarding such subjects asbestos, indoor air quality, and mold. Amongst her asbestos clients have been the radio station housing the ever-complaining Marvin Zindler (reporter best known from his closing of the Chicken Ranch, represented in the film The Best Little Whorehouse in Texas), in the home of Mr. Dolby (Dolby Stereo), and as part of a value engineering study of Pearl Harbor.
Ms. Hess-Kosa’s first technical book was Environmental Site Assessments: Phase I after which she published Environmental Sampling for Unknowns, Indoor Air Quality: Sampling for Unknowns, Indoor Air Quality: The Latest in Sampling Methodologies with editions and more. She has also published several checklist books on environmental health and safety auditing.
