Lectures and Laboratory
3 hours per week of lecture [MWF 9:30-10:20 Engineering 206]
1 hour per week ungraded laboratory [M 2:00-2:50, W 3:00-3:50 BNR 14]
Textbook
Industrial Hygiene Control of Airborne Chemical Hazards, W. Popendorf, 2006.
Course Material
Syllabus, Lecture Notes, Assignments and Laboratories can be downloaded off of USU CANVAS
Course Goals
Students will further explore:
 Principles and physical mechanisms that affect exposures to vapors and aerosols
 Interpreting some occupational health and safety regulations from a physical perspective
 Applications of principles and physical mechanisms to exposures
 Source controls and non-ventilation pathway controls
 Local exhaust ventilation
 Dilution ventilation
Grading
51% Exams: Three one-hour exams (open and closed book format) – at 17% each
16% Assignments: 19 practice problem sets
33% Final Exam
Approximate grading scale:
A:  92%
A-:  90%
B+:  87%
B:  82%
B-:  80%
C+:  77%
C:  72%
C-:  70%
D+:  67%
D:  60%
Greater than 60% is required to pass
Practice Problem Assignments
The highest grade of 17 out of 19 practice problem sets will be used to determine 16% of the final grade (lowest 2 homework
assignment grades are dropped). Due dates for each assignment are listed on the class schedule. To receive consideration for full
credit (10 points), assigned problem sets need to be turned on the due date by the beginning of the start of class (assignments can be
emailed or submitted via canvas). One point will be docked each week day the assignment is turned in late. Up to 5 points will be
docked for late assignments. Please consider turning in assignments even if they are late. Not only will the student receive partial
credit, these assignments will help to keep one current with the material.
Exams
The exams (mid-terms and final) are formatted where approximately half of the exam will be closed/open book (text book/notes). By
recommendation of a student last year, students will be allowed to use one standard note card with equations for the closed book
portion of the exam.
Course Fees
There are no course fees associated with this course. There are lab fees
Special Needs
