Abstract: At 6:30 a.m. on July 16, 2020, Employee #1, in his first day on site, was assisting a crew with HVAC installation inside the attic of an industrial building. While climbing a ladder to access the attic, he was unaware that the roof tiles were not secure and subsequently fell through, dropping approximately 10 feet to the floor. Emergency services were summoned, and the employee was transported to the hospital and admitted for treatment of unspecified broken bones resulting from the fall. This incident underscores the critical need for thorough site assessments and proper training for new employees.
