Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes. 

Wear complete eye and clothing protection. Always avoid touching eyes while working near 

batteries. If battery acid or battery terminal corrosion contacts skin or clothing, wash 

immediately with soap and water. If acid enters the eyes, immediately flood with cool running 

water for at least 15 minutes and get medical attention immediately. Baking soda neutralizes 

battery acid electrolyte. Keep a supply near the batteries.  

 

Do not work alone. Someone should be in the range of your voice or close enough to come to 

your aid when you work with or near electrical equipment.  

 

Remove rings, bracelets, necklaces, watches etc. when working with batteries, photovoltaic 

modules or other electrical equipment. Power from an illuminated photovoltaic array makes a 

very effective arc welder with dire consequences if one of the welded pieces is on your person. 

 

To reduce the risk of injury, connect only deep cycle lead acid type rechargeable batteries. Other 

types of batteries may leak or burst, causing personal injury or damage.
