And That’s Why It’s Called A Memorial Candle

Three intensive care patients in Ukraine have been killed in a hospital fire sparked by a candle lit to remember a recent Covid-19 death.
Another four people are being treated for severe burns following the blaze in Kosiv, western Ukraine, on Tuesday.
According to officials, it began when a candle was lit by a member of staff near five oxygen concentrators – which instantly caught fire.

A member of staff, or to put it another way, the exact sort of person you would expect *not* to do that.
