What protects the operator from laser energy exposure above the maximum permissible exposure when using the First Defender?

• A. Laser shield
• B. Safety goggles
• C. Protective gloves
• D. Shielded helmet

Answer: (A)

Laser safety relies on a barrier that blocks or greatly attenuates the beam so exposure stays below the maximum permissible exposure. A laser shield provides that protective barrier in the beam path, stopping or reducing the radiation before it can reach the operator’s eyes or skin during use of the First Defender. Safety goggles protect the eyes but depend on correct wavelength protection and don’t always guard against reflected or scattered beams, nor do they shield the skin. Protective gloves deal with heat on the hands, not ocular exposure, and a shielded helmet isn’t the standard protection for this laser scenario.
