W501 - Measurement of Haz Substances Substances



To provide the student with a sound understanding of the techniques for assessing exposure to hazardous substances in the workplace and with an understanding of how exposure information can be used to assess risk.


On completing this course successfully, the student will be able to:

ü  describe the general approach to health risk assessment, including the role of atmospheric monitoring;

ü  select appropriate equipment to measure specific airborne contaminants and devise a suitable sampling strategy;

ü  present the results in a form useful for health risk assessment purposes to enable management to comply with relevant legislation.


Ø  4+4 days course [minimum 40 hours including practical/demonstration sessions, lectures, tutorials, guided reading, overnight questions and examination].

Ø  There will be a 40 short answer questions “open book” examination with an allowed time of 120 minutes.

Ø  Practical Studies and Demonstration:

o   The Setting up sampling train

o   Calibration of sampling pumps for

§  dust sampling (Inhalable Dust and Respirable Dust) using filters and

§  vapour sampling using charcoal tubes respectively.

o   Practical demonstration and limitations of air sampling and gravimetric analysis.
