An excerpt from the article 15 facts about La Scala

Another thousand kerosene lamps were located in the rest of the theater. Fire was feared, so hundreds of buckets of water were set up in several rooms. Over time, kerosene lamps were replaced by gas lamps, and these in turn were replaced by electricity in 1883.
