What type of protective gear is indicated for workers using lasers for alignment tasks?

In tasks involving the use of lasers, particularly for alignment, eye protection is crucial due to the potential hazards associated with laser exposure. Lasers can emit intense beams of light that, if directed into the eyes, can cause serious injuries or even permanent damage. Therefore, specific laser safety goggles or glasses that are designed to filter out the hazardous wavelengths of the laser being used are necessary to protect workers' eyes.

While gloves may be important in certain situations to protect from physical contact with equipment, and earplugs can be critical in noisy environments, they are not directly relevant to laser safety. Hard hats are essential for protecting against head injuries in areas where there is a risk of falling objects, but they do not provide any protection against laser light. Consequently, the primary protective gear emphasized for alignment tasks involving lasers is eye protection.
