Reach distances, ESPE separation, crushing gaps and workstation ergonomics — EN ISO 13857 · EN ISO 13855 · EN ISO 13854 · EN 14738

Machine & Scope

Identify the machine and its scope. The AI draft uses the description below to pre-assess which distance topics apply — you review everything before anything is applied.

    Describe your machine and let AI draft applicability (applies / N/A) with justifications for all rows, plus suggested starting values for the calculators below. You review everything before anything is applied — manual entries are never overwritten, and suggested values are only used when you click "Use values".

    Calculators — one global instance each

    Fill in measured values. Results compute live, autosave with the assessment, and are filed in the report as evidence. Screening values only — verify every pass/fail against the current normative text.

    ESPE separation — S = (K × T) + C

    Normal approach K = 2000 mm/s, parallel K = 1600 mm/s. T = t1 (ESPE response) + t2 (machine stopping, measured). C = 8 × (d − 14) for normal approach, 1200 mm otherwise.

    Opening size → safety distance

    Slot, square or round opening of size e — screening value for the required safety distance sr. Openings above 30 mm cannot rely on distance alone.

    EN ISO 13854 · Calculator C

    Crushing-gap minimum check

    Screening minima: fingertip/finger 25 · foot 50 · hand 100 · arm 120 · leg 180 · head 300 · body 500 mm. Check the smallest gap over full travel.

    EN ISO 13857 · Calculator D

    Reach-over height check

    Guard height plus hazard height → required horizontal reach distance sr. Guards below 1000 mm have no table value — raise the guard.
