The eyes and skin are the most susceptible to damage from lasers. Which statement is true?

• A. The eyes and skin are the most susceptible
• B. Lasers affect only internal organs
• C. False
• D. No hazard from lasers

Answer: (A)

The main idea is that laser hazards in workplace settings are most likely to affect the eyes and skin. The eye is particularly at risk because it focuses incoming laser energy onto the retina, which can cause permanent vision loss from even brief exposures with many laser wavelengths. The skin can be burned by the direct or scattered beam, especially with higher-power sources or reflective surfaces. Because these tissues are the first to encounter the beam, they are the most susceptible.

The other statements aren’t accurate because lasers can and do cause harm beyond internal organs, and they certainly pose real hazards to people and eyes, not none at all.
