Reflection Hazards

Specular or diffuse reflections occur when a laser beam inadvertently strikes a reflective object, and these reflections can pose fire hazards as well as hazards to the eye and skin.

Reflection hazards can be minimized by using instruments that have an anodized, matte, or other, non-reflective surface. When protecting non-target tissues by placing an object in front of them, only materials that are designed to withstand direct laser beam impact and that minimize reflection hazards should be used. Never use glass rods for this purpose; thermal stress on the glass may cause breakage.

No matter what a surgical instrument or object is made of, waving it in front of the impacting beam should be avoided whenever possible, and the position of instruments relative to the laser beam should be monitored at all times.
