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.
About a month after i left and never turned up to my shift, the smell started off a cigarette smoke and progressed to Cigar smoke and a combination of other burning smells, un-describable, and non familiar. The smell still remains now nearly 8 months on. It now smells like a wood fire has been put out by water and seems to burn the inside of my nose too. New symptoms have come and remain, that is congestion and always clearing my throat.
