 ### Chemical Spill
 
 1. Wait 30min between the spill and the intervention. 
 2. Wear the appropriate PPE (refer to the safety datasheet).
 3. Plan your work and your sequence of operations to avoid contaminating yourself.
-4. Contain the spill with Trivorex
-5. Sprinkle to cover the entire spill and wait for 10 min
-6. Remove with the shovel from the spill kit and discard it in a plastic bag that will be discarded in the blue bin with yellow cover (solids and liquids contaminated with biologicals and chemicals)
+4. Contain the spill with Trivorex. Trivorex contains a pH indicator. It should turn yellow once the chemical products are trapped, if not, add more Trivorex on the spill until it turns yellow.
+5. Sprinkle to cover the entire spill and wait for 10min.
+6. Remove with the shovel from the spill kit and discard it in a plastic bag that will be discarded in the blue bin with yellow cover (solids and liquids contaminated with biologicals and chemicals).
