What piece of equipment requires the use of safety goggles?

The correct answer is that the use of safety goggles is required when handling the hose with Q-san, a sanitizer commonly used in food preparation areas. Safety goggles are essential to protect the eyes from potential splashes of cleaning or sanitizing chemicals that can cause irritation or injury. In food service environments, where cleanliness and sanitation are critical, the safe handling and application of Q-san is vital, and wearing goggles serves as a preventive measure to ensure the safety of the person using the equipment.

While other equipment mentioned might have safety guidelines, they are not specifically associated with the need for eye protection in the same manner as handling chemicals like Q-san. Using the meat slicer or food processor primarily involves concerns related to blades and injuries from cutting rather than chemical exposure, and the scale does not involve any risks that would necessitate wearing goggles. Therefore, the requirement for goggles when using the hose with Q-san underscores the importance of safety while working with potentially hazardous substances.
