Where injuries happen most

Manufacturing accounts for 81% of all reported incidents, as the high-speed production environment relies heavily on continuous machine operation. The constant interaction between you and rotating tools in these facilities creates a high-risk environment where even a momentary lapse or a failure in machine guarding can lead to catastrophic injury.

Manufacturing 81%
Construction 6%
Wholesale Trade 5%
Professional Services 1%
Public Administration 1%

Real cases like yours

Common patterns in these reports involve you reaching near rotating spindles to measure parts, clear metal shavings, or adjust settings while the machine is still in motion. Gloves and loose clothing are frequently pulled into the equipment, leading to rapid and severe trauma. If any of these scenarios sound like what happened to you, an attorney can help you review the specifics of your incident.
