Whose insurance should cover if you pull a trailer for your company.?

I was pulling a trailer on the clock, ramps came off the trailer and caused some flat tires and bent rims. I went back to where it happend no one was there called the state troopers (which haven't called back and its been 8 days now) left message. My Foreman says it's my insurance, my insurance says its the company's insurance. I don't want to open a claim cause it will look bad on me.
