Summary

This was a quick tour of seven principles of occupational health. Occupational health refers to the application of the principles of public health to prevent illnesses and injuries and promote health in workplaces for all workers. It is about fitting the work to the worker and the worker to the job. Occupational health differs from environmental health in a number of different ways, most importantly, with occupational health, the intensity and duration of exposure to agents is higher or greater than what is expected in an environmental health setting. New Zealand statistics show that some professions are more susceptible to occupational health related diseases than others, and occupational epidemiology has some distinct properties such as a more or less captive population that allows for surveillance and retrospective cohort studies easier to conduct than in the community. Finally, while many different ways to control exposures through legislation, technology modification, and human behavioural modifications exist, injury prevention through Haddon matrix provides a useful framework that can be applied widely in the context of occupational health.
