Which PPE is necessary to protect your face from splashes while checking on a stirring solution?

The necessary personal protective equipment (PPE) to protect your face from splashes while checking on a stirring solution is goggles. Goggles are designed specifically to shield the eyes and the surrounding area from hazardous substances that may splash, especially in a laboratory setting where chemicals and reactions are involved. They provide a secure fit around the eyes, preventing the entry of any liquid or debris that could cause injury or irritation.

While gloves are important for protecting the hands from chemicals, and a lab coat is essential for safeguarding clothing and skin from spills, they do not provide direct protection to the face and eyes. A mask helps prevent inhalation of harmful vapors but does not protect the eyes from splashes. Therefore, goggles are the most appropriate choice for ensuring face and eye safety when working with stirring solutions in the lab.
