| Risk of injury
to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant. |
Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses. |
