DIN EN ISO 14122-3 sets critical safety requirements for permanent industrial access, mandating specific dimensions for guard-rails (minimum 1,100 mm height), stairs, and stepladders to prevent falls. It mandates rigorous verification through physical testing or calculation to ensure structural integrity. For a detailed look at the 2016 standard, visit ISO 14122-3:2016(en) .

Industrial machinery and plants require safe, reliable access for operators and maintenance personnel. Working at heights inherently carries risks of slips, trips, and catastrophic falls. To mitigate these hazards, the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN) established the series.

Guard-rails are mandatory when the risk of a fall exceeds 500 mm, or when the gap between a platform and a structure (wall/machine) is greater than 180 mm. The top rail must be at least 1100 mm high.
