What is the minimum height of safety railing surrounding open excavations?

The correct minimum height of safety railing surrounding open excavations is 1.5 meters. The regulations regarding the safety of open excavations have been established to ensure the protection of workers and the public from falls into unsafe areas.

The rationale for this height is based on national safety standards that recognize the need for a railing capable of preventing individuals from falling over or climbing over it. A height of 1.5 meters provides an adequate barrier to deter falls, and it is consistent with similar regulations found in construction safety protocols.

Understanding these standards is crucial for compliance with building laws and ensuring a safe working environment around excavation sites. The other options presented do not meet the regulatory requirements for safety railings at excavations, underscoring the importance of adhering to the established measurement to safeguard individuals in these potentially dangerous areas.
