Hydrofluoric (HF) acid, one of the strongest inorganic acids, is used mainly for industrial purposes (eg, glass etching, metal cleaning, electronics manufacturing).

It can be difficult to pinpoint the exact cause of a burning smell in nose. Thatâs because the potential causes are many. One possible explanation for this symptom is sinus congestion.

Dry nose alone rarely causes serious consequences. Seek immediate medical care (call 911) if dry nose occurs with symptoms of a serious condition such as difficulty breathing or a high fever (higher than 101 degrees Fahrenheit). Seek prompt medical care if your dry nose is persistent or causes you concern.
