Startling new figures have prompted the state government to announce a $2.2 million injection into protecting the safety of health professionals in next year's state budget.

It was revealed there were more than 11,000 incidents of violence and aggression against WA health system professionals in 2016 - that is, 30 "code blacks" in Perth's three major hospitals a day.

Code blacks are used by hospital staff to alert others of a potential or existing aggressive incident towards a staff member, and the McGowan Government detailed its new plans to help health workers feel safe - including "antistab vests".

"Over the next three years, WA Health will purchase 250 antistab vests for the State's major hospitals, and 2,500 personal mobile duress alarms to reduce the risk of injury at home visits and to help protect staff in remote nursing posts," a statement from Health Minister Roger Cook's office said.
