What is the maximum distance from the still step bottom to the top of the rail?

The maximum distance from the still step bottom to the top of the rail is typically designated as 22 to 24 inches. This measurement is crucial for ensuring proper safety and accessibility for workers who need to perform maintenance or inspections on rail systems.

Rail safety standards establish specific distances to facilitate safe access and prevent accidents caused by improper heights for workers using stairs, platforms, or other access points. Measuring within this range helps maintain the ergonomic safety of workers by allowing for easier and safer movement when climbing up to the rail level.

Additionally, standard operating procedures and regulations are also designed to conform to these measurements, promoting a safe working environment. This is why the option indicating 22 to 24 inches is the correct answer, aligning with established safety and industry guidelines.
