Before inspecting a fiber optic endface, which action should be taken?

• A. Turn off transmitting devices
• B. Leave devices on
• C. Remove all PPE
• D. Begin immediately without checks

Answer: (A)

Safety first: ensure no live laser or transmitter is active before you inspect a fiber endface. Turning off transmitting devices stops any light from the fiber or equipment from escaping or reflecting into your eyes or toward the inspection optics. That reduces the risk of eye injury and protects the equipment from unexpected activation during the inspection. Keep to the safety procedures you’ve learned, including using appropriate PPE and checking that the system is de-energized, before you begin. Leaving devices on would keep the laser active and hazards present; removing PPE or starting without checks ignores critical safety steps and could lead to harm or damage.
