According to Cal/OSHA law, a vertical walled trench exceeding what depth must be shored?

According to Cal/OSHA regulations, a vertical walled trench that exceeds 5 feet in depth must be shored. The shoring is required to ensure the safety of workers who may be exposed to cave-ins or falling materials while working in or around the trench. At depths greater than 5 feet, the risk of trench collapse increases significantly, which is why regulatory measures are established to protect workers.

Understanding this depth requirement is crucial for maintaining workplace safety and compliance with regulations. For trenches that are 5 feet deep or more, specific shoring methods, such as using trench boxes or other protective systems, must be implemented to create a safe working environment. This regulation reflects the industry’s commitment to reducing the risk of accidents and injuries on job sites, ensuring that workers can perform their tasks without undue risk.
