The loader smelled fumes, and tried to turn on the fan but turned off the light instead. I guess he didn't understand up is on and down is off. It takes about a minute for the light to come on, so this smart fellow decided he would use his lighter to see in the trailer. HE SMELLED FUMES AND THOUGHT LIGHTING A FLAME WAS A GOOD IDEA. This guy is lucky to have come out unhurt, but I think he may be out of a job. I think with a decision making process like that he will survive to an old age.
