How do safety glasses function as personal protective equipment (PPE)?

Safety glasses function as personal protective equipment (PPE) primarily by protecting the eyes from impact and chemicals. They are designed to shield the eyes from flying debris, which can occur in various work environments, particularly in construction, manufacturing, and laboratories. Materials like polycarbonate or other high-impact resistant materials are often used to construct the lenses of safety glasses, which enhances their ability to withstand and absorb impacts, thereby reducing the risk of injury.

In addition to impact protection, safety glasses are also effective at guarding against chemical splashes or irritants. Certain environments, especially those involving the use of hazardous materials, may require specialized safety glasses that provide additional protection, such as a chemical-resistant coating or side shields to prevent splashes from reaching the eyes.

Understanding this function of safety glasses is crucial for anyone working in potentially hazardous environments, as they are an essential part of a comprehensive safety program aimed at reducing the risk of eye injuries. The other options involve different protective measures that do not pertain specifically to the primary function of safety glasses.
