EN ISO 13857 Safety Distance Calculator
Determine the minimum safety distance to a hazard zone through regular openings
What Is the EN ISO 13857 Safety Distance Calculator?
EN ISO 13857 — Safety of Machinery — establishes safety distances to prevent hazard zones being reached by upper and lower limbs when reaching through openings in machine guarding. Rather than cross-referencing tables in an Excel spreadsheet, our free EN ISO 13857 safety distance calculator lets you quickly determine safe distances by entering the opening shape, size, and height of the hazard. Simply input your values to get the correct machinery safety distances for calculating safety distances in line with the standard — no download required.
Table 4 from EN ISO 13857:2019 — Minimum safety distances for reaching through regular openings, for persons of 14 years of age and above. All dimensions in millimetres.
