Do I have to calculate all my hazards and tasks this way?

Simply put, yes, you do! Don't stress too much though. Since you're a SafetyWallet member, you have access to OHS Online, which means you can create your risk assessment online, which means you can create your risk assessment quickly and efficiently. Simply find and select your task from our library of tasks and insert it into your risk assessment. The hazards associated with the task will automatically be displayed. You simply need to quantify them and then move on to your next task! How cool is that!
