He flipped out on me

My truck broke down last week and the supervisor shows up and tells me it’s MY fault because I did not do a good enough pre-trip. What happened was my other idiot supervisor strapped down a tire onto the catwalk and the strap broke, wrapped around my driveline and then tore up all my airlines. I told her it wasn’t me that did that. She then FLIPS out on me gets in my face and says that she doesn't need my attitude WHAT?!!!. The whole time I tried to get her to calm down but she wouldn’t. Guess I made her look bad. I told my boss about it and basically he said that I might be fired because I screamed at her and refused to listen. I did NOT scream. What the hell am I going to do now? Can he actually fire me over something that was not my fault??! Help!!!!
