Hi Doctors, Issue: Inhaled chlorine gas while cleaning the bathroom ( Mixed acid with Red color harpic) @ 10.00 am today morning No cough, breathlessness etc till 1.30 pm today. I have been to pulmonologist and chest x-ray done ( nothing abnormal seen) Doctor advised to use nebulizer and breath out. (He told me that sometimes people may develop pulmonary edma & lung damage due to.this chlorine in take .. and symptomps like cough,fever, breathlessness etc...is that true?asked me to come down in such cases) What are the precautions to be taken to avoid future problem due to this. Will this incident lead to lung damage in future? Pls tell me...I'm really worried May God bless you all.
