Honestly I very much questioned the purchase of the gas mask, but rationalized it as peace of mind, and potential for real life application for welding in poor ventilation or, galvanized.

The paint mask would have probably functioned just as well, provided that it covers the whole face. The air was so toxic, that even after the fire was extinguished the electrician's eyes were burning and he had to pull his shirt oner his mouth and nose to breathe.
