Should Industrial Hygiene be capitalized in a sentence?

"Industrial Hygiene" should be capitalized when it refers to the specific field of study or profession.

Here are some examples:

* Correct: "I am studying Industrial Hygiene at the university."

* Correct: "The company hired an Industrial Hygiene consultant to assess the workplace."

However, if "industrial hygiene" is used in a general sense, without referring to the specific field, it should not be capitalized:

* Correct: "The company needs to improve industrial hygiene practices."

* Correct: "Industrial hygiene is important for protecting workers' health."

In essence, follow the same rules for capitalizing other fields of study like "Medicine," "Engineering," or "Psychology."
