A fire or electric shock may occur...

Hello Alan, Mister Micawber, Beeesneees, Mordant, Esl_Expert and other native English speakers,

-------------------------------
A fire or electric shock may occur if you continue to use the appliance in an abnormal condition such as when it is smoking or emitting odor.
-------------------------------

Do you see any errors?

Seems okay. I also think this is one of those times when the plural 'in abnormal conditions such as' would work just as well as the singular.
