I just looked again, and yeah, the covers are right next to it. Just put them back on. You definitely need to call the phone company though. You need a nid with hi voltage protection, you dont seem to have any. I'm not familiar with that exact terminal, but I dont see any protectors at all, unless they are hiding beneath that metal steel panel below the screw posts.
You could get protectors for the 66 blocks but you shouldnt have to, the utility needs to give you protected lines. If I got it I'd just put up a bid or two big enough to cover your working lines and fill any holes in the terminal with fire. putty and make sure the ground is good.
