What is a recommended safety precaution when working with batteries?

Wearing splash-proof goggles is a recommended safety precaution when working with batteries because they help protect your eyes from potential hazards associated with battery handling. Batteries, particularly lead-acid types, can emit corrosive substances and gases. In the event of a leak, rupture, or explosion, these substances can splash or spray, posing a serious risk of eye injury. Splash-proof goggles provide a barrier that helps ensure your eyes are shielded from harmful materials, which is critical for maintaining safety in environments where battery operations occur.

While other options like insulated gloves are also important safety measures, the correct choice here emphasizes eye protection specifically. Maintaining personal safety while handling batteries is paramount, and using appropriate protective gear, including splash-proof goggles, effectively reduces the risk of injury.
