The Industrial Environment: It's Evaluation & Control
DHHS (NIOSH) Publication Number 74-177
Industrial hygiene is the science of protecting man’s health through the control of the work environment. Man and his environment are indivisible. They react upon each other in the form of a “give-and-take” relationship. Frequently it is assumed that man moves through his environment and molds it to his desires; however, it may be more productive to think of the environment and man as moving through and changing each other simultaneously.
