Is any of this happening?
Be seen today
Seek prompt medical advice if symptoms suddenly worsen, you develop a fever with breathing difficulty, or you have been involved in a significant chemical spill or fume exposure.
3
Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have a cough lasting more than several weeks, regularly bring up phlegm, or notice symptoms linked with work.
Assessment is also appropriate if you have recurrent “bronchitis,” wheezing, or gradually increasing breathlessness.
These signs are not routine features of industrial bronchitis and may indicate a serious inhalation injury or another medical problem.
Every sign above is quoted from the sofidex article on Industrial bronchitis. If you are not sure, err upward — it is always reasonable to be checked.
