3 Introduction Sources of Robotic Hazards Accident Types Guarding Methods Installation, Maintenance, and Programming Worker Training and Supervision Summary Conclusion Deploying Industrial Robotics

4 Introduction –Robots defined. Industrial robots. Devices/sensors required for performance. Sequencing/monitoring communication interfaces. –Common robotic functions. Materials handling, assembly, welding, painting, etc. Perform unsafe, hazardous, repetitive tasks. Deploying Industrial Robotics

5 Introduction –Shift in U.S. manufacturing to automation. –Innovation and acceptance of robotic technology. –Potential exposure to severe/fatal accidents. –Recommendations for safe operation. Deploying Industrial Robotics

6 Introduction –Guidelines for Robotics Safety “Both state and federal regulations deal with industrial robotics safety, including the federal Occupational Safety and Health Act of 1970 (OSHA).” These guidelines are aimed at three aspects of the robotic work area: –Keeping unauthorized persons outside of the work cell. –Protecting workers from fixed machinery. –And protecting workers from the robot itself. »(Fuller, 1999). Deploying Industrial Robotics

7 Introduction –Guidelines for Robotics Safety (continued) These regulations apply only to the normal operation of the robot –(Fuller, 1999). Abnormal operation includes: –Programming. –Maintenance. Deploying Industrial Robotics

8 Introduction –Guidelines for Robotics Safety (continued) “Recent studies in Sweden and Japan indicate that many robot accidents do not occur under normal operating conditions but rather during programming, adjustment, testing, cleaning, inspection, and repair periods. During many of these operations, the operator, programmer or corrective maintenance worker may temporarily be within the robot work envelope while power is available to moveable elements of the robot system.” –STD – pub – Guidelines For Robotics Safety Deploying Industrial Robotics

9 Introduction –Sources for Guidelines/Recommendations: Occupational Safety and Health Administration (OSHA). –Guidelines for Robotics Safety, STD –Industrial Robots and Robot System Safety – OSHA Technical Manual, TED A. Deploying Industrial Robotics

10 Introduction –Sources for Guidelines/Recommendations (continued) : National Institute of Occupational Safety and Health (NIOSH). –Preventing the Injury of Workers by Robots, PUB No Deploying Industrial Robotics

11 Introduction –Sources for Guidelines/Recommendations (continued) : American National Standards Institute (ANSI). –Industrial Robots and Robot Systems – Safety Requirements, ANSI/RIZ R –Manufacturing Systems/Cells, ANSI B International Organization for Standardization (ISO). –Safety of Integrated Manufacturing Systems, ISO Deploying Industrial Robotics

12 Introduction –Guidelines/Recommendations Summarized Sources of robotic hazards. Accident types. Guarding methods and control devices. Installation, maintenance, and programming. Training and supervision of workers. Deploying Industrial Robotics

13 Sources of Robotic Hazards –Human error. –Control error. –Unauthorized access. –Mechanical failures. –Environmental sources. –Power systems. –Improper installation. Deploying Industrial Robotics

14 Accident Types –Impact. –Crushing. –Trapping. –Mechanical part injuries. Deploying Industrial Robotics

15 Guarding Methods –Interlocked barrier guards. –Fixed barrier guards. –Awareness barrier devices. –Presence sensing devices. –Emergency stops. –Audible and visible warning systems. Deploying Industrial Robotics

16 Guarding Methods (continued) –Interlocked barrier guards. Physical barrier around robot work envelope incorporating gates equipped with interlocks which will stop automatic operations when opened. –Fixed barrier guards. A permanent fence requiring tools for removal. Deploying Industrial Robotics

17 Guarding Methods (continued) –Awareness barrier devices. Defines a safety perimeter intended to prevent inadvertent entry into the work envelope. –Presence sensing devices. Detect a person stepping into a hazardous area near a robot. Deploying Industrial Robotics

18 Guarding Methods (continued) –Emergency stops. Dangerous robot movement is arrested by dynamic braking systems rather than simple power cut-off to counteract the effect of robot inertia. Deploying Industrial Robotics

19 Guarding Methods (continued) –Audible and visible warning systems. Not acceptable safeguard methods but may be used to enhance effectiveness of positive safeguards. –Control devices. Located outside the robot work envelope. Deploying Industrial Robotics

20 Guarding Methods (continued) –Control devices. Photoelectric (light field). Radio-frequency. Electromechanical (contact bar). Pullback. Restraint devices. Safety trip. Two-hand controls. Gates. Deploying Industrial Robotics

21 Installation, Maintenance and Programming –Installed in accordance with manufacturer’s guidelines and applicable codes. –Verify compatibility with environmental conditions. –Power to robot conforms to manufacturer’s specifications. –Robot is secured to prevent vibration movement and tip over. –No additional hazards are created. Deploying Industrial Robotics

22 Worker Training and Supervision Managers. Operators. Engineers. Programmers. Maintenance personnel. Bystanders. Deploying Industrial Robotics

23 Worker Training and Supervision (continued) –Safe operation. –Maintenance. –Emergency procedures. Shut down controls. Inspection of safeguards. –Disciplinary action. –Working with teams. –Proper attire. Deploying Industrial Robotics

24 Summary –Review guidelines from OSHA/NIOSH/ANSI/ISO. –Identify risks associated with robotics. –Reduce hazards inherent to robotics. –Reduce risk of accidents and injuries. Deploying Industrial Robotics

25 Conclusion –Keeping well informed of these guidelines and risks signifies employers’ commitment to the safety and health of their employees. Deploying Industrial Robotics
