What is the preferred clearance for handholds?

The preferred clearance for handholds is typically 2 1/2". This measurement is important for ensuring safety and ease of use for workers accessing rail cars and equipment. A clearance of this size allows for comfortable grip and access, reducing the risk of injury when personnel are climbing or descending. It accommodates a range of hand sizes and ensures that individuals can securely grasp the handhold without excessive strain or awkward positioning.

A clearance that is too small may hinder safe operation, while a clearance that is overly large could result in decreased stability or support. Thus, the 2 1/2" minimum is established as a standard that balances safety and practicality in rail maintenance and machinery operation contexts.
