How these injuries happen

Most injuries occur when you lose your footing on uneven terrain, embankments, or loose gravel. Falls on the same level account for 85 percent of all reported incidents, often happening when a surface gives way or lacks proper stabilization. These accidents frequently occur during routine movement across outdoor work sites where the ground condition is not maintained or clearly marked.
