A new bill signed into law on Friday by Gov. Jerry Brown will require major league sports stadiums in California to have clearly posted the numbers fans can use to call or text-message stadium security, both inside and outside the venues, according to an article from MercuryNews.com.

Assembly Bill 2464, the Improving Personal Safety at Stadiums Act, was authored by Assemblyman Mike Gatto (D-Los Angeles), who notes that while contact information for stadium security is often announced over the intercom at the beginning of the game, but many fans don’t remember these numbers as the event goes on, the article says.

Posting these signs, Gatto says in the article, will enable incidents to be resolved more quickly, potentially prevening serious injuries.
