SAFETY DISTANCES - EN ISO 13855 S = K x T + C Afstand tot de gevarenzone < 0,5m (ingrijpen) Toenaderingssnelheid = 2000 mm/s Afstand tot de gevarenzone > 0,5m (inlopen) Toenaderingssnelheid = 1600 mm/s Stopping/run-down time of the overall system in seconds (s) Approach speeds of the body or parts of the body (mm/s) distance = distance from the nearest hazardous point to the safe detection point (mm) 2018 SICK Seminar Workshop Safe Engineering 11 SAFETY DISTANCES - EN ISO 13855 S = K x T + C Is the additional distance in millimeters that represents the intrusion into the hazard zone before the protective device is triggered (mm) Stopping/run-down time of the overall system in seconds (s) Approach speeds of the body or parts of the body (mm/s) distance = distance from the nearest hazardous point to the safe detection point (mm) 0 c C C 2018 SICK Seminar Workshop Safe Engineering 12 SICK Seminar 2018 Safe Engineering 6

INSTALLATION AND COMMISSIONING FOLLOWING THE SAFETY DESIGN Technical protective measures, Implementation of the safety functions 2018 SICK Seminar Workshop Safe Engineering 17 OVERALL VALIDATION OF THE MACHINE SAFETY coaching Technical protective measures, Implementation of the safety functions Placing on the market Requirements machinery directive 1. Essential health and safety requirements relating to the and construction of machinery (annex I) 2. Technical file for machinery (annex VII) 3. Operating instructions 4. Right EC conformity procedure for machinery (annex VIII to X) 5. EC declaration of conformity of the machinery (annex II) 6. CE marking (annex III) 2018 SICK Seminar Workshop Safe Engineering 18 SICK Seminar 2018 Safe Engineering 9
END USER RESPONSIBILITY coaching Technical protective measures, Implementation of the safety functions Placing on the market End user responsibility q Shall have the duty to ensure the safety and health of workers in every aspect related to the work q The minimum safety and health requirements of the directive shall be met è National regulation (extra) demands must be followed as well q q Before the first use of the machine q Repeat of risks over the whole life cycle of the machines q Take measures to ensure that the machine throughout the whole life will still comply to minimum requirement of the directive (maintenance and inspection) q Initial inspection before the first use of the machine q After assembly at a new site or in a new location Stop time measurements are an important part of periodic q Periodic inspection inspections to validate if the existing safety measures are still q Adapting to technical progress è state of the art installed at the right safety distance so that a safe stop of the machine is guaranteed before a person can reach into the hazardous movement 2018 SICK Seminar Workshop Safe Engineering 19 SAFETY VS PRODUCTIVITY Excellent! 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
