Does welding smoke invalidate the fast?

Question : Peace be upon you. And upon you be peace. We work at a company and are forced to do welding work. My question is: it produces smoke, and we are forced to inhale it, meaning there is no way to avoid it, even if we wear masks, it reaches the throat, and this happens every day in Ramadan.

Answer : There is no need for me to say that there is no blame on you. There is no blame, if Allah wills.
