IH is code for "industrial hygienist," a codename that provides cover for one of the most important and rewarding jobs on Earth: protecting people from danger at work and in their communities.

These professionals use the latest breakthroughs in science, technology, engineering, and research to anticipate potential threats. Many of these threats surround us on a daily basis, an unseen enemy IHs are trained to recognize and fight.

IHs are everywhere; here's just a fraction of industries they work in:
  • Chemical companies
