Answer: toeboard
Explanation: The Occupational Safety and Health Administration defines the Walking-Working surfaces regulation for the secure construction of stairs in industrial environments. For platforms or walls that are 4 feet or higher above the ground and do not have surrounding walls, it is mandatory to build a standard railing around them.

A toeboard is an equipment fixed vertically to prevent items from falling for the platform.
