  • Avoiding use of air pressure to clean batteries
  • Avoiding breathing fumes when electrolyte is added
  • Avoiding spilling or dripping electrolyte
  • Using correct jump start procedure
If acid is spilled on skin or in eye:

1. Flush skin with water.
2. Apply baking soda or lime to help neutralize the acid.
3. Flush your eyes with water for 15-30 minutes. Get medical attention immediately.

1. Do not induce vomiting.
2. Drink large amounts of water or milk, but do not exceed 2 L (2 quarts).
