The requirement for toe boards and guardrails is based on ensuring worker safety while working at elevated heights. OSHA specifies that guardrails must be installed when workers are at heights of 6 feet in the construction industry, as this is the minimum height at which employees could be exposed to a fall hazard that could cause serious injuries or fatalities.

Toe boards, which are used to prevent tools, equipment, and materials from falling off the edge of a platform, are also required at the same height. Therefore, the correct height for the installation of both guardrails and toe boards is indeed at 6 feet, not at heights such as 8, 10, or 12 feet, which do not align with the established regulations.

This is critical for compliance with safety protocols in construction sites and helps to mitigate risks associated with falls from elevated surfaces.
