Abstract: At 1:00 p.m. on July 31, 2012, Employee #1, a night custodian employed by the Conejo Valley School District at Westlake High School sustained a skull fracture while stripping a classroom floor. Conejo Valley School District at Westlake High School is a local government entity that provides secondary education in their local community. Employee #1 has been employed with the Conejo Valley School district for approximately 16 years as a custodian. At the time of the accident, Employee #1 was working with a coworker and engaged in stripping a classroom floor at the worksite. Blitz Build up Floor Stripper was mopped on the floor by Employee #1. Blitz Build Up Floor Stripper is a chemical that breaks down wax on the floor and brings it to the surface, making the treated area slippery. As Employee #1 was walking across the floor to work with the stripper machine, he slipped and fell onto the tile floor, striking his head. Employee #1 sustained a cranial fracture. The coworker witnessed the accident. Employee #1's supervisor was at the worksite, however he did not witness the accident. Employee #1 was hospitalized for treatment.
