Explanation of the Graphic 9-10-12-15 Medium Risk, we need to lower it in a shorter time, eg: 1 week To understand the graphic, we shall look at some examples 55 5 10 15 20 We always need to go step by step. And PPE should be always at the last step 25 16-20 =High Risk. We try to minimize the risk on the same day 25 = Emergency. We stop working. Apply precautions, minimize the risk =
