What is the proper first-aid response when a truck driver suffers chemical acid burns to the eyes or skin from a ruptured battery?

1. Rinse immediately and continuously with copious amounts of clean running water for at least 15–20 minutes and call emergency medical services
2. Apply dry sand directly into the eyes
3. Rub alcohol or gasoline onto the acid burn
4. Cover the eyes with airtight tape without rinsing
