What protects the operator from laser exposure?

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

Answer: (D)

Protection against laser exposure mainly comes from engineering controls that physically block the beam. A laser shield acts as a barrier that blocks or absorbs the laser light, preventing direct and scattered radiation from reaching the operator. It’s designed to cover the beam path or the workspace and is tailored to the wavelength and power used, so exposure is kept at safe levels.

Safety goggles protect the eyes, but they only work if the beam could reach the eyes and don’t prevent exposure to other parts of the body or to reflected light. Protective gloves shield skin from heat or contact, but they don’t stop the light itself from entering the area. So the shield provides the primary protection by blocking the laser at the source or along the beam path.
