SAFETY DISTANCES - EN ISO 13855 S = K x T + C Afstand tot de

Afstand tot de gevarenzone > 0,5m (inlopen) Toenaderingssnelheid =

(s) Approach speeds of the body or parts of the body (mm/s)

detection point (mm) 2018 SICK Seminar Workshop Safe Engineering

distance in millimeters that represents the intrusion into the

Stopping/run-down time of the overall system in seconds

Good! Required level of safety and increased productivity Required level of safety and no decrease of productivity Appropriate Acceptable? Unacceptable! NO! Required level of safety with acceptable negative influence on productivity Required level of safety but annoying warning signals (visual and acoustic) Required level of safety but obstructs the operator with unintended production stops as result No protection INTELLIGENT SAFETY IMPROVES PRODUCTIVITY Motivation for manipulation!! 2018 SICK Seminar Workshop Safe Engineering 20 SICK Seminar 2018 Safe Engineering 10
