What class of laser is a PLDR?

• A. Class 3
• B. Class 4
• C. Class 2
• D. Class 1

Answer: (B)

Laser safety classifications rate how dangerous a device is to eyes and skin and what controls are needed to use it. A Pulsed Laser Designator emits very short, high-energy pulses to mark targets for laser-guided munitions. Those pulses have high peak power, so even brief direct exposure can cause serious eye injury, and the beam can ignite flammable materials in the field. That level of hazard requires stringent controls and safety measures, which is why a PLDR is classified as Class 4. Lower classes cover progressively less hazardous devices: Class 1 is inherently safe, Class 2 is eye-safe for momentary exposure, and Class 3 (R and B) involves greater risk but not the same level of fire hazard and control requirements as Class 4.
