A man (not OD) was killed today crushed between two trailers and another was killed last week about the same way. I've seen units roll off and bang the driver while he was doing his walk around.I know of a driver parked in the yard filling out his logs when a switcher plowed into him full bore,I've seen drivers slip and fall getting in the tractor and coming out,I've watched jiffs (dollies) crossing the yard come loose because they were not latched.All these things happen at each and every freight line sooner or later.It just seems like people relax a little when they get on a terminal's yard and are not as safe.You can move the loads 600 miles every time with no problems but if you get on the yard and clip the t/m's car you will have no friends.Be careful.
