Wet cell batteries.
Common, ordinary automotive batteries are classified as wet cell batteries because they use liquid electrolytes, a medium of exchanging electrons, instead of a pasty electrolyte used in dry cell batteries.
Each year they are responsible for minor mishaps such as peeling paint and electrical shocks, and more serious problems
like severe eye injuries, acid burns and catastrophic fires.
The Zurich Risk Engineering Department has published a Loss Prevention safety brochure covering the precautions that need to be taken when working with these batteries.
