I watched a fellow RC'er using a pair of needle nosed pliers to tighten a zip-tie, he slipped off and planted them in his forehead. We tried pulling them out but we couldn't do it (I think they wedge themselves in like a fish spear), he had to go to the hospital to get them out. No pic's but he still has the two little dimple scars hahahaha.
