The standard dictates the relationship between the rise (height of the step) and the going (depth of the step). This is often calculated using the "step formula" to ensure a natural walking rhythm.
Treads must withstand a concentrated load of 1.5 kN distributed over a mm square without excessive bending.
The top rail must be at least 1100 mm above the walking surface.
Stairs are preferred over ladders whenever the space allows, as they offer a safer, ergonomically superior angle of ascent. The standard defines stairs as having an angle of inclination between .

The globally recognized standard for this is . Specifically, Part 3 (DIN EN ISO 14122-3) dictates the design, dimensions, and safety requirements for stairs, stepladders, and guard-rails.
The modest cost of the official PDF – typically less than the hourly rate of a safety engineer – is a worthwhile investment for the assurance of having the correct, complete, and legally recognised standard.
To fully understand Part 3, it helps to know where it fits in the series: The standard dictates the relationship between the rise
In industrial environments, safety is paramount, particularly when it comes to accessing machinery and elevated working platforms. is a critical international standard that specifies the requirements for non-powered stairs, stepladders, and guard-rails, ensuring they provide safe access to machinery.

The DIN EN ISO 14122-3 standard is an indispensable technical resource for any safety engineer, machine designer, or plant operator. By adhering to its precise specifications for stairs, stepladders, and guard-rails, you are not only complying with legal regulations but also actively preventing fall-related injuries. For industrial applications in Germany, the official DIN EN ISO 14122-3 PDF remains the definitive source for safe and lawful access design. The top rail must be at least 1100
In the realm of machinery safety, the focus is often on guarding moving parts or emergency stop mechanisms. However, a significant portion of industrial accidents occurs not during the operation of the machine, but while accessing it for maintenance, cleaning, or adjustment. This is where plays a critical role.
This article provides a complete overview of the standard, explains where to find the official PDF, highlights key technical requirements, and discusses implementation best practices.
Applies only to means of access that require tools to remove (e.g., screws, welding).
