Contractor Management, Auditing, ISO Training

Training that helps organisations strengthen health and safety performance through effective contractor management, auditing, and management systems.

Under the Health and Safety at Work Act 2015 (HSWA), PCBUs cannot contract out of their health and safety responsibilities. Organisations need effective systems and processes to manage contractors, monitor performance, and support continual improvement. This becomes particularly important where responsibilities overlap and businesses must consult, cooperate, and coordinate to manage shared risks. IMPAC's contractor management, auditing, and ISO courses help build the knowledge and capability needed to strengthen health and safety performance across an organisation.

IMPAC Training

Category overview

Handing a contractor a site map and a generic safety manual won't protect people or manage critical risks. Assuming someone else is managing the risk is exactly how critical risks slip through the cracks. Effective contractor management and management systems rely on clear responsibilities, active oversight, and processes that can be implemented, monitored, and verified in practice.

For more than 25 years, IMPAC has helped organisations build the capability to manage contractors, implement, strengthen and verify that systems and processes are working as intended. Our courses use realistic workplace examples, discussion, and practical activities to connect theory with the realities of managing health and safety in practice.

Whether you are responsible for contractor oversight, procurement, health and safety management, or auditing, these courses help build the capability to strengthen systems, verify effectiveness, and support continual improvement.
