Quick interlude:
A close family member of mine noticed this Shabbos that there were problems with their hotplate while checking the guidelines circulated by the London NW Hatzola. By the time they managed to do something about it, it was already smoking and parts of it were glowing orange (I am not clear of the details).
Boruch Hashem everyone is safe, and because of the increased awareness they managed to notice before it was too late.
