HLTAID014 builds on Provide First Aid for higher-risk workplaces where you may be the senior first aider on scene. It adds two-rescuer CPR, secondary patient assessment, vital signs monitoring, and management of serious conditions including life-threatening bleeding with tourniquets. You'll also learn to triage multiple casualties, coordinate other responders, and liaise with emergency services — the qualification typically required for designated First Aid Officers on medium-to-high-risk sites.
