Module 4: ORGANIC DUSTS

OBJECTIVES
By the end of this module, you should:
  1. have an overview of the various sources of hazardous exposure to organic dusts and the major agents responsible for the health effects observed;
  2. be familiar with some of the common occupational diseases associated with organic dusts and the immunological mechanisms involved;
  3. be familiar with some of the common occupational allergic diseases and the body systems involved;
  4. be familiar with the causes, clinical features and management of organic dust toxic syndrome and hypersensitivity pneumonitis;
  5. be familiar with the health effects associated with common organic dusts in occupational exposure settings such grain, cotton and wood dust.

This introductory page contains links to other pages in this section. These are included for your convenience, both for reference and for revision purposes. It is strongly recommended, however, that you first access the material in its logical sequence, indicated by the "Next Page" link above.

ACTIVITIES:

  1. A lecture will provide the overview. Revise these notes.
  2. Work through the exercise.
