Injuries during working hours at a construction site leads to several legal consequences. If a person gets injured at working site, he/she can file civil law suit for negligence or product liability.
In the above situation, Flo was not wearing any safety wear while working on the construction site of a Grider company. She can file a product liability suit against the Girder company.
The company can most successfully raise the defense of "negligence". Since Flo was not wearing any safety wear during her working hours, the company can raise the defense of negligence because she knew that working on construction site without wearing safety gears may cause harm to her.
