Abstract:
At 1200 on November 7, 2019, a Dual-Axis Radiographic Hydrodynamic Test Facility (DARHT) Experiments and Diagnostics (J-4) worker (W1) removed a fiber optic laser cable from alaser diagnostic system without turning off power to the Erbium-Doped Fiber Amplifier (EDFA), in violation of the hazardous energy control process stated in the Integrated Work Document (IWD). W1 immediately recognized the error, reconnected the cable and removed the key from the EDFA. W1 did not recognize the potential hazard and continued work without notifying management. On November 13, 2019, while discussing work, W1 mentioned the incident to his J-4 Group Leader (GL). The GL immediately made the necessary notifications and escorted W1 to LANL Occupational Medicine (OM). OM personnel evaluated W1 and released him back to work with no restrictions. J-4 personnel removed the equipment from service pending the procurement of an additional safety device. There was no impact to personnel safety, health or the environment.
