Which of the following is an important safety precaution when handling electrolyte?

Wearing rubber gloves and goggles is a crucial safety precaution when handling electrolyte due to the potentially hazardous nature of the substances involved. Electrolytes often contain corrosive materials that can cause chemical burns or irritation upon contact with skin or eyes. Rubber gloves provide a protective barrier, ensuring that these hazardous materials do not make direct contact with hands, which can lead to injury or chemical exposure. Additionally, goggles protect the eyes from splashes or vapors that can cause serious damage or irritation.

The other options do not provide adequate protection. Wearing a short-sleeve shirt would leave arms exposed to hazardous substances. Using glasses without side shields exposes the eyes to splashes from the sides, which can be especially dangerous when handling corrosive materials. Breathing in deeply does not relate to safe handling practices and can actually increase the risk of inhaling harmful vapors. Thus, the combination of rubber gloves and goggles represents a comprehensive approach to safety when dealing with electrolyte handling.
