A loader’s eyes are splashed with a Class 8 liquid. After moving the person to safety, what first-aid step matches usual written-instruction guidance?

1. Rinse the eyes with the eye-rinsing liquid (or clean water) for a prolonged period and seek medical help, taking the transport document or UN information
2. Neutralize the eyes with whatever acid or alkali is on the vehicle
3. Keep the eyes closed and wait an hour before rinsing
4. Rub the eyes with a dry cloth soaked in diesel
