On, January 6, 2020, an employee was unloading a steel delivery of 15' 9'' long "I" beams. After the steel was taken off the truck by a forklift, it was set down on two A-frames and rolled to a storage location by two employees. There was one employee on each A-frame. The steel on the A-frames was on uneven ground near a curb and sewer drain while the employees waited for help to remove it from the A-frames and place it on the ground. While waiting, one employee walked in between the A-frame and sewer grate, which is slightly pitched for drainage, placing one foot on the curb and the other on the grating with his back to the steel beam. The A-frame slowly started moving down toward the grating. Once the front wheel of the A-frame hit the grating, it tipped over, causing the steel beam to roll toward the ground and land on the employee's leg, knocking him to the ground. He suffered a broken ankle and was hospitalized.
