How tall must the top rail on a personnel platform be in relation to the platform floor?

The height of the top rail on a personnel platform is crucial for ensuring safety and compliance with industry standards. A top rail that is 39 inches high provides a sufficient barrier to prevent personnel from falling off the platform, while also being at a height that allows for easy use and access. This measurement aligns with the requirements set by safety regulations, which are established to protect workers in various settings, especially in construction and maintenance environments.

Choosing a height that is too low may not offer adequate protection, leaving workers vulnerable to falls. A top rail height that is measured at 39 inches strikes a balance between safety and practicality, ensuring that it is high enough to serve its purpose effectively without being excessively tall, which could hinder movement and usability on the platform.
