When should eye protection be used in the lab?

Eye protection should be used in the lab whenever there is a risk of chemical splash or flying debris because these hazards pose a significant threat to eye safety. Chemicals can cause severe damage upon contact with the eyes, potentially leading to permanent injury or vision loss. Similarly, flying debris, which may be generated from various activities like cutting, grinding, or even accidental breakage, can cause physical harm to the eyes. Therefore, wearing appropriate eye protection, such as safety goggles or face shields, is essential to safeguard against these types of hazards and maintain a safe working environment in the laboratory.

The other options do not encompass the comprehensive nature of when eye protection is necessary. For instance, limiting eye protection only to laser work does not account for a broader range of potential hazards present in many lab activities. Similarly, handling dry materials may not always pose a significant risk to the eyes. Finally, relying solely on personal judgment as to when to wear eye protection lacks the consistency required for effective safety protocols in the lab, making it less reliable as a safety practice.
