You would want to make sure that the face shield is rated for electrical work and not just a general duty face shield (grinding splatter resistant).
We had a representative from a major fuse manufacturer give us Arc-Flash and PPE information. We were shown a video of two "dummies" dressed in various PPE. One dummiy had all electrical (fire-resistant) PPE, and the second dummy had on cotton clothing and a general duty face shield.
They staged an actual arc-flash incedent about two feet (arms length) typical of electrical work, in front of the two dummies side-by-side. Immediately after the flash, the second dummies face shield was FULLY afire, and blobs of flaming dripping plastic were falling all down the front of dummy #2. This video is etched deep into my memory.
Early in my career, we often did 480v high current hot work. I had one arc-flash accident (NO PPE). I was for the most part unharmed, however a few hours later, I got "welders-eyes", very painful, but nothing a hospital could fix. The pain subsided after a few hours. I am extremely lucky. I am now grateful for the arc-flash / PPE awarness training. I will NEVER be exposed to those hazzards again.
