Online minimum safe distance calculator helps to calculate the the minimum safety distance or height at which a hard guard or protective device should be installed.
The different non-separating guarding device will have some variation of this general formula. ISO 13855’s general formula for the minimum safe distance is: S = (K x T) + C
Formula:
S = (K x T) + C
where,
S is the minimum distance,
K is the human approach speed,
T is the total stopping time,
C is the intrusion distance
