When working with acid, such as when filling batteries, splash-proof _______________ must be worn.

When working with acid, safety goggles must be worn to protect the eyes from any potential splashes or fumes that can occur during battery maintenance. Acid can cause serious chemical burns or damage to the eyes, so wearing safety goggles is crucial for preventing injury. It is important when handling hazardous materials to prioritize eye protection as part of personal protective equipment (PPE). The goggles provide a barrier that protects the eyes from harmful substances, ensuring that the technician can work safely and effectively. Other protective gear such as gloves, aprons, or work pants may be important as well, but in the context of direct threats to the eyes, safety goggles are essential.
