Personal protective equipment is essential in which of the following situations?

Personal protective equipment (PPE) is vital when you are exposed to hazardous materials because it serves as a barrier between the worker and potential contaminants that can cause harm. Hazardous materials can pose risks such as chemical burns, respiratory issues, and other health hazards; therefore, using appropriate PPE—such as gloves, respiratory devices, protective clothing, and eye protection—is crucial to safeguard workers from these dangers.

While using household chemicals may sometimes require PPE depending on the nature and level of hazard, it's generally not comparable to the complexities and dangers found in environments where hazardous materials are present. Routine office tasks do not typically involve exposure to hazardous substances, hence the necessity for PPE is greatly diminished in those scenarios. Therefore, the situation of being exposed to hazardous materials undeniably warrants the use of personal protective equipment to ensure worker safety and compliance with safety regulations.
