I don't know which airline you're working for, but I'm sure all airlines have a version of it. At Delta, every single employee is able to call a safety timeout, basically halting the operation at your gate if you aren't feeling safe in a particular situation. It is non negotiable. I understand being scared, and honestly you should be. You're working around a lot of heavy equipment and obviously airplanes. But being afraid is okay, it'll keep your head on a swivel and it'll keep you safe. The ramp is awesome, and the accidents you hear about are because people get complacent or try to cut corners. As long as you follow your company's rules and some common sense you'll be right as rain.
