It is sad reading the impact section at https://en.wikipedia.org/wiki/Davy_lamp

"The introduction of the Davy lamp led to an increase in mine accidents, as the lamp encouraged the working of mines and parts of mines that had previously been closed for safety reasons."

and

"Another reason for the increase in accidents was the unreliability of the lamps themselves. The bare gauze was easily damaged, and once just a single wire broke or rusted away, the lamp became unsafe. Even when new and clean, illumination from the safety lamps was very poor, and the problem was not fully resolved until electric lamps became widely available in the late 19th century."

Seems like it wasn't as successful as it is made out to be in this article.

An extreme example of https://en.wikipedia.org/wiki/Risk_compensation. I was somewhat disturbed when I first learned that this is what actually happens.
