Where injuries happen most

Manufacturing accounts for 71 percent of all entanglement cases, as the high volume of automated production lines creates constant exposure to moving parts. You face elevated risks in this sector when your employer fails to enforce strict lockout-tagout procedures or removes physical barriers that prevent contact with dangerous machinery components.

Manufacturing 71%
Wholesale Trade 5%
Transportation & Warehousing 4%
Construction 4%
Administrative Services 4%
Other 12%

Real cases like yours

Reports consistently show that injuries happen when you interact with equipment that is still powered or lacks adequate guarding. Common patterns include fingers caught in valves, limbs dragged into roller dies during training, or arms trapped while clearing jams on conveyor belts. If any of these scenarios sound like what happened to you, an attorney can help you review the specifics of your incident.
