Did I inhale toxic gases?

Hello

I work at Burger King and have done so for a while. We have at the restaurant this big machine that flame-grills frozen burger meat put into it.

Recently however, there were some inspectors visiting the restaurant, checking some things with the machine. In an attempt to fix something I presume, something happened which led smoke to come out and fill the entire restaurant. The smoke was dense and of gray color – it had a vicious smell of fat/oil and meat.

I was standing at the machine while this happened; I inevitably inhaled the smoke directly for app. 5 minutes.

I didn’t have any acute symptoms afterwards, maybe a little breathlessness; a feeling that air didn’t fill my lungs as effectively as usual. It is now a couple of days later and I guess I’m fine, but now I’m more concerned with the potential long-term effects of this inhalation of smoke.

Could this have caused any permanent (maybe long-term) damage to any of my organs?
