What does tight-fitting goggles provide protection against?

Tight-fitting goggles provide essential protection against various hazards encountered in metal cutting and other machining operations. They are specifically designed to shield the eyes from impact from flying objects, such as chips and debris generated during cutting processes. Additionally, goggles help protect against splashes from liquids that could irritate or damage the eyes.

The design of tight-fitting goggles ensures a secure seal around the eyes, minimizing the risk of materials entering from the sides, which can happen with looser-fitting eye protection. This makes them particularly effective in environments where metal particles, dust, and other potential irritants are present. The robust construction of the goggles also adds a layer of impact resistance to safeguard against accidental hits from tools or equipment.

Therefore, they are crucial for maintaining eye safety in industrial settings, which is why the correct answer highlights protection against impact, dust, chips, and splashes. Other choices, such as protecting against sound, heat, or vibration, do not accurately reflect the primary purpose and functionality of tight-fitting goggles in a machining context.
