Sterilizing masks with a Crock Pot slow cooker

The only mains lines are the thick lines. How much further could I space them from the coil side? The trace is 1.5 mm in width, and there's about 3 mm width. 3 mm is good for at least 500 volts.

Anyways, I could see it could be improved, so I improved it. Thank you.

This PCB is not earthed, so you should use reinforced creepage. BTW you did not fix it completely.

Ok, I moved the relay away and moved the track. Should be ok now?

Should be fine in terms of safety. BTW some pads you use are too small.
