When personnel are required to enter excavations over what depth must a means of entry and exit be provided for every specified horizontal travel distance?

The requirement for providing a means of entry and exit for personnel working in excavations is established in safety standards to protect workers from hazards related to confined spaces and prevent accidents. When the depth of an excavation exceeds a specific amount, employees are at increased risk of cave-ins, and having a safe way to enter and exit the excavation becomes critical for their safety.

In this context, the correct choice specifies that when personnel are required to enter excavations that are more than 4 feet deep, a means of entry and exit must be provided for every 25 feet of horizontal travel distance within the excavation. This requirement ensures that in case of an emergency or if workers need to evacuate quickly, they have a safe and accessible way to do so.

The stipulation of 4 feet as the critical depth aligns with safety regulations aimed at reducing the risks associated with excavations. The horizontal travel distance of 25 feet ensures that there are adequate access points within the excavation, further enhancing safety for workers. This is particularly important in larger excavations where travel distances can be significant, increasing the need for multiple access points.

Providing a means of entry and exit is vital for maintaining worker safety and compliance with safety standards in excavation work. It allows for quick escape routes
