Case Description/Summary: The gym bleachers at a public school moved when a parent attempted to climb them. The accessible bleacher section slid closed and trapped the parent’s leg which caused the parent to fall and sustain injuries.
Expert Analysis: A field inspection of the incident location was performed, and a defect was found to exist in the accessible portion of the bleachers. When the accessible bleacher section was pushed to the open position, latches were supposed to lock it in place. However, the latches had not been installed correctly at the manufacturer. When the bleachers had first been installed in the gym by a professional bleacher installation firm many years prior to the incident, they took no corrective measures to fix the problem. The bleachers were also missing some of the critical latching hardware right from the start. A school maintenance worker discovered that some hardware had been missing long after the installation had been performed, and he asked the installer to send the missing hardware to him, which they did. Even after the missing hardware had been installed by the school maintenance department, the accessible section of bleachers would not latch and lock in the open position. As that accessible section was supported on rollers, it would roll freely in either the open or closed directions with the application of any bidirectional force – such as applied when a person tries to climb them.
