Violent patients are seen flinging chairs and lunging at staff at Royal Melbourne Hospital in shocking footage released by workers who are calling for an end to the chaos.

In graphic video played on televisions in the hospital's waiting rooms, staff sitting behind wired barricades at the emergency department are forced to contend with erratic patients lashing out with whatever means possible.

The video is part of a protest from hospital staff who are tired of being abused after almost 7500 incidents were recorded in 2017,

There were 7439 "code grey" incidents last year, up 85 percent over the past four years. There were also nine "code black" incidents involving aggressive patients with a weapon.

Emergency department nurse unit manager Susan Harding hoped the video would spark action from hospital authorities to keep workers safe.

“We hope the video, which incorporates examples of what emergency staff experience and CCTV footage of actual incidents, has a positive effect on people in the ED waiting room and watching this on social media,” she said.

“We want our patients and visitors to understand we are committed to providing the best possible care for them, but to do this we must ensure the absolute safety of the people who provide that care."

Ms Harding said there had to be a significant mind shift in the workplace and in the community about what was acceptable.

“In healthcare we sometimes tend to think that occupational violence and aggression is ‘just part of the job’,” she said.

“But occupational violence and aggression wears many different hats and takes many different forms.

"We really wanted to change the thinking and help our staff to understand that violence and aggression in their workplace is unacceptable, and that’s not what they come to work for every day."
