When to Consult a Doctor

Speak with your physician if you experience persistent respiratory symptoms (chronic cough, wheezing, shortness of breath), unexplained headaches, skin irritation, or unusual fatigue — particularly if these worsen when you're at home. Mention your proximity to a TRI facility so they can order appropriate screening. Vulnerable populations — children, elderly, pregnant women, and those with asthma — should be especially vigilant.
