Welding fumes from 2 car garage

[kansasc10]

Im welding in some floor pans in my 72 c10 using a mig setup with c25 in my attached 2 car garage. The living area of my house is on the next floor up and about 50 feet down from the garage. The garage has 8 foot ceilings and is seperated from the house by an exterior door. Im welding on 18ga mild steel with .030 wire at intervals of 10 minutes or less with breaks of 30 min to an hour in between for a couple hours a night. My question is, do you think the fumes from my welding are in high enough concentration to pose any risk to individuals on the next floor and 50 feet away? I know its impossible to say for sure or not but do you think it warrants clearing the house of occupants prior to welding or should I worry about it enough to invest in testing air samples? Or do you think the concentration (if any) would be so low that I shouldn't worry about it. Thanks in advance.
