A Provisional Improvement Notice (PIN) is a notice that is issued to a person requiring them to address a health and safety concern in the workplace. A PIN may be issued if a HSR reasonably believes that a person is contravening or has contravened a provision of the Act in circumstances that make it likely that the contravention will continue or be repeated. A HSR can issue a PIN only if the HSR has completed an approved HSR training course, or previously completed that training when acting as a HSR of another work group.
