What type of eye protection is required when hazards exist?

Safety glasses or goggles are required eye protection when hazards are present because they are specifically designed to provide a barrier against potential eye injuries. These types of eyewear are constructed from impact-resistant materials that can withstand flying debris, chemicals, and other hazards commonly encountered in various work environments such as construction sites or manufacturing facilities.

Safety glasses typically have side shields for additional protection, while goggles offer a complete seal around the eyes, preventing particles and liquids from entering. This level of protection is crucial for maintaining eye safety and preventing injuries that could result from exposure to hazardous materials or conditions.

In contrast, regular sunglasses do not offer the same level of impact protection or resistance to chemical splashes. Face masks serve a different purpose, primarily protecting the mouth and nose, and contact lenses do not provide any physical barrier to protect the eyes from impact or hazardous substances. Thus, safety glasses or goggles remain the appropriate choice in environments where eye hazards are present.
