School lockers move as heavy, anchored banks that become genuine tip hazards the moment they are unbolted, so the plan has to include stabilizing helpers, not just tools.
Pro tip: Separating a locker bank into its individual bolted-together sections turns one dangerous, oversized load into several manageable sections that are far safer to carry and dolly.
Watch out: A locker bank that is unbolted but still standing is a serious tip-over hazard; never leave one free-standing without a helper stabilizing it until it is secured again or laid down safely.
