Which of the following is commonly used PPE in a laboratory setting?

• A. Notebook
• B. Hammer
• C. Goggles
• D. Brush

Answer: (C)

Eye protection is a fundamental part of personal protective equipment in a laboratory. Goggles shield the eyes from chemical splashes, flying particles, and fumes, and they fit snugly to prevent hazards from reaching the eyes from the sides. Because eye injuries can happen quickly and be serious, wearing goggles is a standard practice during many lab tasks, often alongside gloves and a lab coat. The other items—notebook, hammer, and brush—are not protective gear; a notebook is for recording data, while a hammer and a brush are tools for work or cleaning. Goggles specifically provide the protection needed for common lab hazards, making them the most appropriate and commonly used PPE in a laboratory setting.
