## Narrative

While attempting to repair a leak on the antiscalant line, the EE was inspecting the piping to determine the correct diameter and obtain the appropriate fittings for the repair. The EE released the line, causing it to suddenly recoil and whip back. As a result, antiscalant solution was splashed toward the EE's face, bypassing the safety glasses and entering EE's right eye.
