ABC's "The Rookie" has decided to ban "live" weapons from its set following the fatal shooting that took place on the set of Alec Baldwin's "Rust" on Thursday.
The new policy is effective immediately, showrunner Alexi Hawley informed his staff on Friday, according to reports.
"As of today, it is now policy on The Rookie that all gunfire on set will be Air Soft guns with CG muzzle flashes added in post. There will be no more ‘live’ weapons on the show," his memo states via The Hollywood Reporter.
"As always, if you ever feel unsafe or witness anything that concerns you, please don't hesitate to report it," it concludes. "My door is always open."
ALEC BALDWIN WAS TOLD FIREARM WAS UNLOADED, SEARCH WARRANT SAYS: REPORT
Reps for ABC and "The Rookie" did not immediately return Fox News' request for comment.
The new policy was announced just one day after cinematographer Halyna Hutchins was killed by a prop gun used during rehearsals by Baldwin, who is a star and producer of the movie. Director Joel Souza was also injured and taken to the hospital. Actress Frances Fisher wrote on Twitter that Souza has since been released.

An assistant director on the New Mexico movie set claimed that a gun being handed to Baldwin on Thursday was unloaded, a search warrant filed in a Santa Fe court said, according to reports.
"Cold gun," assistant director Dave Halls announced at the time, using lingo for an unloaded firearm, before a rehearsal for the movie, The Associated Press reported.
Soon afterward, court filings say, Baldwin pulled the trigger of the firearm, fatally wounding Hutchins and wounding director Souza.
Halls was unaware live rounds were inside the firearm he grabbed and handed to Baldwin, a detective wrote in an application for the search warrant, the AP reported.
