IH 400/500: Industrial Hygiene Sampling and Analysis

Offered in Winter

·        Class Meetings plus Laboratory

·        Laboratory Session are USUALLY Fri, 1:00 p.m.-4:00 p.m.

Required Text:

• The Occupational Environment – Its Evaluation and Control (1997). AIHA press.
  Although the book is expensive and heavy, it is used in four (4) IH courses, making its per course cost less than $30.00. It is also on permanent reserve at Alden Library (call #RC 967 D54 1997).

Course Description: This course will provide a basis for familiarity with common industrial hygiene sampling approaches, techniques, equipment, and considerations. The students will study the theoretical basis for specific sampling methods, and will participate in laboratory sessions aimed at demonstrating the application of these methods.

Course Objectives: Impart competency to the student in the selection, use, and interpretation of industrial hygiene sampling equipment, and confidence and insight regarding the interpretation of results obtained with/by the methods.

Course Format: Lectures and labs

Attendance: Each student is expected to attend class and will be held responsible for material content as presented in class, including syllabus changes and assuagements made by the instructor in class. Attendance will be recorded.

Grading and testing: Grades will be assigned per catalog (4 point scale). There will be two midterms and a comprehensive final exam, in addition to a requirement to complete typewritten laboratory reports on a timely basis. The two midterms and final will each be worth 25% of the course grade, with the remaining 25% allocated to satisfactory laboratory report submissions. No make-up exams or labs will be offered.  Grades will be assigned as follows:

GRADE CRITERION PERCENT COMMENTS
Mid-Term Exam 30 %
Final 30 % (Not comprehensive)
Laboratory Reports 40 %
Attendance, Tardiness borderline grades see description above

For example, if a student had the following percentage scores:

Mid-Term Exam 88%
Final 91%
Lab Reports Average 90%
His or her course grade would be calculated as follows:

(88 X .3) + (91 X .3) + (90 X .4) =
26.4 + 27.3 + 36.0 =
Weighted Score Sum = 89.7
This value rounds up to 90, resulting in an "A-" for the course.

 Laboratory Reports:: Lab reports will be graded on a 10 point scale, consisting of 0--10; a score of 0 indicates a failing grade for the report, while a grade of 9.4 or better indicates excellent performance. Reports are due within one week following the actual lab session, and reports turned in late (i.e., after 4:00 pm Fridays following the lab) will lose one letter grade, and then one letter grade per week from their earned grade value. Therefore, no credit is possible for even an “A” level reports turned in 3 or more weeks late.

Lab Sessions: The lab sessions are the key to success in achieving the course objective. For that reason, any unexcused absence from the lab sessions will result in an automatic ½ grade point lowering of the student’s overall course grade. This policy will be strictly enforced.

Lab topics to be covered may include:

• Quality control and quality assurance
  Calibration of low-flow sampling pumps
  Non-viable particulates (dusts) sampling
  Gas and vapor sampling instruments
  Gas and vapor sampling media use
  Airflow measurements and calculations
  Noise surveys and dosimeters
  Bioaerosol sampling
  Heat and cold stress evaluation
  Ventilation, Indoor Air Quality (IAQ) evaluations
  Information Procurement
