A review into Alec Baldwin's deadly shooting of Halyna Hutchins on the scene of Rust has spotted that management "knew that firearm safety procedures were not being followed".
New Mexico safety regulators have levied the film company a maximal $139,793 (£107,019) after an "avoidable loss of life occurred".
They affirmed it "demonstrated plain indifference to employee safety by failing to review work practices and take corrective action".
Cinematographer Hutchinson passed away after a hand gun held by Baldwin blasted a live ammunition during a practice session in October 2021.
The entertainer was one of the stage director of the Western, as well as its celebrity.
"Our investigation found that this tragic incident never would have happened if Rust Movie Productions, LLC had followed national film industry standards for firearm safety," said state environment official James Kenney.
"This is a complete failure of the employer to follow recognised national protocols that keep employees safe."
The account included attestation that managers took restricted or all bark and no bite over two foregoing boomerang on location.
It also chronicled security challenges that went overlooked and said sharp shooters were forbidden to decide about refresher course.
The company's dossier stipulated that it would follow ground rules but have not yet done so, added the Occupational Health and Safety Bureau (OHSB) report.
Those guidelines included:
Not bringing live ammo onto any studio or lot; holding daily safety meetings when guns are used; and that staff "refrain from pointing a firearm at anyone" except after consulting the armourer or other safety rep.
Rust Movie Productions affirm it contradict with the pronouncement and proposed to appeal.
"Our thoughts and prayers remain with Halyna's family," it said.
have insisted the gun blasted after Baldwin pointed at Ms Hutchins during a scene rehearsals. The film's director, Joel Souza, was also wounded.
Baldwin has said he was showing the gun at her directive and that it blew off without him discharging the trigger.
The accounť said assistant director David Halls, who doubles as safety coordinator, had handed over Baldwin the hand gun without communicating sharp shooters in the midst or afterwards the moment it was loaded.
Baldwin is at the moment facing several legal proceedings, including from script supervisor Mamie Mitchell and head of lighting Serge Svetnoy, as well as Ms Hutchins' family.
After the statements release, his advocate said it "exonerates" Baldwin by "making clear that he believed the gun held only dummy rounds" and that he had "no authority" over the safety matters pinpointed.
"We are confident that the individuals identified in the report will be held accountable for this tragedy," said Luke Nikas.
Mitchell's lawyer, Gloria Allred, said the account was a "stinging indictment which goes way beyond mere negligence".
"Everyone responsible for what happened on that production which led to the tragedy should hang their heads in shame," said Ms Allred.
Another examination into possible criminal charges is underway.
In a December interview, Baldwin recounts that while he "would go to any lengths to undo what happened", he does not feel remorse over the deadly shooting and saying that while "someone is responsible for what happened... I know it's not me".
He said Ms Hutchins was "somebody who was loved by everybody and admired by everybody who worked with her".
The occurrence also brought about calls from politicians for expansion of state-sponsored firearms training.
New Mexico's OHSB said its investigation enclosed 1,560 hours of staff time, 14 interviews, and review of 566 documents.
Hutchins, 42, resided at an army base in the Russian Arctic, where her father worked in the navy, before relocating to Los Angeles to study film.
She was considered an upcoming celebrity in her field.
