Prerequisites: PCS 106, ENH 220 or permission of the School.

OHS 523 Occupational Health: Safety Evaluation Techniques Lect: 3 hrs.

The techniques used in evaluating hazards, exposure and risk are studied in this course. The major techniques covered include inspections, investigations, job safety analysis and material flow analysis. Assessments specific to certain types of hazards are reviewed.

Prerequisite: OHS 208.

OHS 588 Occupational Health: Ergonomics in Design Lect: 3 hrs.

Examines basic principles of ergonomics with emphasis on designed environments. In lectures, readings, and discussion, students will encounter an ergonomics approach to person-task system models and human factors in design with regards to the working population and general user population. The implications of physical (sensory and cognitive) factors within ergonomics are reviewed from the perspective of the design of workplaces and other spaces for human use.

Prerequisites: Third-year standing in a design-related program or permission of the instructor.

OHS 608 Occupational Health: Hazard Recognition and Control Lect: 3 hrs.

This course introduces the techniques of hazard recognition and control and examines specific hazards—primarily of a physical and safety nature. Hazard recognition and hazard control are shown to be interrelated since inadequacies of control measures in themselves may constitute hazards.

This course is not open to ENVO, ENVS or ENVC students.

OHS 621 Occupational Health: Occupational Hygiene Methods II Lect: 2 hrs./Lab: 1½ hrs.

This course continues a study of the various sampling and analytical techniques necessary for determinations of exposure and risk, particularly to chemical agents. Monitoring equipment and processes are an important part of this course, as are existing standards and guidelines for exposure. A critical view is taken of interpretation of sampling and analytical results.

Prerequisites: OHS 422, OHS 421 (formerly OHS 411 and OHS 321).

OHS 623 Occupational Health: Safety Control Methods Lect: 3 hrs./Lab: 1 hr.
