 An efficient
environmental control of the working processes (aspiration and air
exchange installations) is extremely important in the prevention of
occupational asthma. In fact, many of the subjects exposed to sensitizing
agents have reported symptoms of asthma after acute accidental exposures
to high concentrations of such agents. Another important preventive
element is the early identification of the susceptible subjects. Atopy,
in fact, represents an important predisposing factor for occupational
asthma due to high molecular weight substances, whereas the role of
bronchial hyperresponsiveness is still debated. Finally, early diagnosis
of the disease and early removal of the subject from the exposure to the
noxious agent can modify the prognosis.
