EHOs are primarily concerned with protecting the public from the harmful exposures they may encounter in the environment and with improving its health. EHOs act as advisers, educators and enforcers, and carry out site visits and give assistance to individual householders and businesses and to managers and workers.

In certain circumstances, they take enforcement action to ensure compliance with legislation designed to protect the health of the public.

Some EHOs work in the private sector advising business of their legal duties.

Many EHOs pursue a general career and deal with a wide range of functions. An increasing number become specialists in specific areas of Environmental Health.

Wherever they work, EHOs have the same goal – to improve and protect public health.
