Course Description

TEEX OSHA Training Institute Education Center LogoThe OSHA Guide to Industrial Hygiene (OSHA #521) course covers industrial hygiene practices and related OSHA regulations and procedures. Course topics include recognition, evaluation, and control of chemical, physical, biological and ergonomic hazards, Permissible Exposure Limits (PEL), OSHA health standards, respiratory protection, engineering controls, OSHA sampling protocols and strategies, and workplace health program elements. The course features workshops in health hazard recognition, OSHA health standards and use of sampling equipment. Upon course completion, students will have the ability to recognize basic industrial hygiene principles and practices, identify characteristics of common air contaminants, locate PELs, perform basic industrial hygiene calculations, and determine methods for hazard control and abatement.

Course Completion Requirements

Participant Must Provide

  • a photo identification on the first day of class. See the Participant Handbook for approved forms of identification and additional guidelines.

Attendance Requirements

TEEX and the OSHA Training Institute (OTI) have an attendance policy that requires participants to fully attend an enrolled class in its entirety (100% of the course). We realize that extenuating circumstances may arise that would take a participant out of class and have a policy to handle those situations. If a participant misses less than 20% of the class, he/she may be able to perform makeup work equivalent to the class time missed. If 20% or more of the class is missed, the participant may attend a makeup course upon approval by TEEX’s OTI Education Center Director.
