Integral to the Safety and Health Management System is risk assessment.
All workplaces must conduct risk assessments to identify the source of
risks and shall take all reasonably practicable  steps to eliminate any foreseeable
 risk to any person who may be affected by the undertaking in  the workplace.
Where it is not reasonably practicable to eliminate the risk, other reasonably
practicable measures must be taken to minimise the risk.

Risk assessment, together with communication of risks, review and monitoring of the risk
assessment, is part of the risk management process.
