I am an Industrial Hygienist working for Lockheed Martin on a government contract. In case you don't know what an IH is, I get this all the time, a IH is the following:
Industrial Hygiene: Science and art devoted to the anticipation, recognition, evaluation, prevention, and control of those environmental factors or stresses arising in or from the workplace which may cause sickness, impaired health and well being, or significant discomfort among workers or among citizens of the community.
I mainly monitor the workplace by conducting air sampling and other measurements. Currently I have been doing alot of heat stress monitoring.
