Depends on what you're doing.
I've been shocked (120VAC) enough times that my nickname around one workplace was Sparky.
Took a sideways tumble off a customer's table that I was (stupidly) using as a makeshift ladder cause I was too lazy to get mine out of the van. Luckily a bruise was all I got out of it.
Had a strong gust of wind blow my extension ladder off the distribution when I was halfway up and untethered. I held on expecting the strand hooks to catch, then the whole ladder turned 90 degrees as it slid off the smooth cable and the weight distribution changed. I jumped off and landed hard but was otherwise ok, very lucky. The ladder hit the ground with enough force that it bent the strand hooks at least an additional inch or two inwards, and after I got the ladder back on the van I couldn't bend them back into shape hanging off of them with my lineman's pliers. This could have been avoided in training because we were originally (wrongly) taught to keep the top of the ladder extended 2-4 feet past the distribution. After that I made it a point to put the strand hooks right on the distribution.
Had my corded roto-hammer catch a nice big rock in someone's foundation once, jamming the bit but the body of the drill kept turning. Wrenched my arm pretty good. Those things have a LOT of torque.
Had a coworker cut off a piece of messenger on a drop cable while my face was next to it and got it right in the eye. That was unpleasant. Worse than that I was hanging a fiber drop and trying to get it to clear a tree, and backed into a large bush that I didn't immediately feel (heavy jacket, winter time). Somehow I'd bent a fairly strong branch with my arm or body and it suddenly let go and whipped me square in my right eyeball. That required an ER trip and several weeks of healing but otherwise no permanent injury.
Been in several customers' homes where I needed to put on disposable boot covers and respirators due to black mold in the basement. Those were always very unpleasant. The upside was they tended not to care if the quality of the install was quick and dirty.
I somehow managed to snip my palm with my trusty Klein sidecutters while cutting a piece of RG6 once.
And also had several near-misses with @ssholes while I was doing aerial work and the cones, amber flashing lights, and vehicle obstructing the roadway wasn't enough of an indicator the road was closed. I always tried to keep a lane open if practical but sometimes I'd need to cross the road with a drop, and idiots would still try to penetrate my worksite. More than once some hardware or tools "accidentally" fell onto impatient vehicles. Oops.
