Prevent workers from being pinned between equipment and a solid object

- Take measures to prevent workers from being pinned between equipment and a solid object.
Employers are required to take measures to prevent workers from being pinned between equipment and a solid object, such as a wall or another piece of equipment; between materials being stacked or stored and a solid object, between shoring and construction materials in a trench. Other example situations are: During demolition operations, when balling or clamming is being performed, only the personnel necessary to the work must be allowed in the work area. The employer must make sure that proper bracing is used between heavy plates used as shoring in a trench. The employer must carefully arrange the path of travel when loading/unloading, stacking, and storing materials so that no workers will be caught between materials and moving equipment or between materials and a wall.
