What type of eye protection should a worker wear if they are exposed to or observing a welding operation?

regular safety glasses
flame proof screens or goggles
face shields only
none, personal discretion

The correct answer is: flame proof screens or goggles

In a welding operation, workers are exposed to bright sparks, intense ultraviolet (UV) and infrared (IR) radiation, which can cause serious eye injuries if proper protection is not used. Flame proof screens or goggles are designed specifically to protect against these hazards. They provide a barrier that shields the eyes from harmful light, flying debris, and the intense heat generated during welding. While safety glasses offer some level of protection, they are not sufficient on their own for welding tasks due to their inability to fully shield against radiation and particles emitted during the process. Face shields can provide additional coverage but should be used in conjunction with goggles rather than as a standalone solution. Choosing "none, personal discretion" disregards the significant risks associated with exposure to welding operations, emphasizing the importance of adhering to safety protocols and guidelines for eye protection in the workplace.
