Hydrofluoric (HF) acid, one of the strongest inorganic acids, is used mainly for industrial purposes (eg, glass etching, metal cleaning, electronics manufacturing). Hydrofluoric acid also may be found in home rust removers. Exposure usually is unintentional and often is due to inadequate use of protective measures.
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. A lot of people suffer from this, so you shouldnât rule it out. People with sinus problems sometimes smell things that arenât there, too.
Another common cause of burning of the outer nose is an infection usually of the nasal passages. The common cold is an acute viral infection where a runny nose and sneezing are the main symptoms. The inflammation may extend to the outer nose but usually burning is a result of excessive wiping. There are several different infectious agents that can cause rhinitis (nose inflammation) which may also affect the sinuses (sinusitis) or throat (pharyngitis).
