I poured bleach into a drain and fumes came out. How do I get rid of the fumes? Should I evacuate my house?
Open all the windows and turn on some fans if you have them.. If your throat or eyes burn or you notice any trouble breathing at all get out. If you have birds or other pets you should move them outside.
In addition to DeanaWynn's advice, turn on the water and let it run.
Was there drain opener in the drain?? NEVER, NEVER, mix bleach with anything!!!!!
