Do I have a case if I was let go at work after doing what my boss said then getting shocked by 480 3 phase electric volt?

I was told by my boss to cut into a PVC drain line. After using a manlift and going up to the line, I reliazed it was not PVC. It was steel pipe. I stopped the job and went and got my supervisor. He came to the job site and also brought the planner and engineer. After 30 minutes of discussions, they said they made a mistake, it's not PVC. It's the steel pipe. They stood there on the ground and watched me and told me to cut it. As soon as I started cutting into it, it blew the saw out of my hands, blinded me for several minutes. The shock actually knocked me several feet. Then they took me to a walk in clinic which would not see me. They said I needed my heart and everything checked out so they just took me back to the job site then next week I was terminated. Do I have a case?
