SÉANCE VII

  • The purpose of this assignment is not to turn you into a IH/CIH, although that would be just fine. Instead, you want to learn about what Industrial Hygienists or Certified Industrial Hygienists do. Therefore, you know more about when you might need one or how they can help you or your organization.
  • So watch these four short videos
  • Perform an internet search for masters Industrial Hygiene programs. Pick one that catches your interest and study it a little deeper.
  • Write a paragraph about the one video that caught your attention the most and tell why.
  • On the same page, write a paragraph about the masters IH program that caught your attention and tell why. Be sure to specify the program

This is the Book
