In which situation is it essential to wear eye goggles?

Wearing eye goggles is essential when handling hypochlorites due to the potential hazards associated with these chemicals. Hypochlorites, commonly used as disinfectants and bleaching agents, can release harmful fumes and splashes that could irritate or severely damage the eyes. Protective eyewear helps to shield the eyes from any accidental exposure to solutions or vapors that may occur during handling, mixing, or application processes.

In comparison, while reading safety data sheets is an important safety practice, it does not inherently involve a risk of eye exposure. Using a ladder, although it has its own safety considerations, does not typically pose a direct threat to eye safety. Similarly, filling out permits is a task that generally does not involve any hazardous materials that would necessitate eye protection. Hence, the context of handling hypochlorites makes it clear that eye goggles are an essential safety requirement in that scenario.
