Safety - Part II
Workcell Steup Safety Requirements
- Implement Lockout devices
- Use anti-tie-down logic
- Use appropiate arrangements within the workcell
- Identify the bounds of the robot's range of motion before teaching/running production
- Position the controller outside the workcell
- Use a libel amount of Emergency Stop buttons
- Implement safety devices (i.e. fences, interlocks, light curtains, etc.)
- Check safety joints
- Check for appropriate electrial conditions
- Eliminate pinch points
Robot Manual Operation Safety Requirements
- Use appropiate clothing when operating the robot
- Periodically inspectic the robot
- Periodically inspectic the workcell for hazardous materials or spills
- At most one person should be operating the robot at a time
- Do NOT enter the workcell when the robot is in operation
- Be familiar with evacuation routes
- Isolate the robot from any remote signals
- Test each program in both step and continuous modes before running in production
Robot Automatic Operation Safety Requirements
- Be familiar with workcell space and evacuation routes
- Understand the task, which the robot will perform, in its entirety
- Do NOT enter the work envelope when the robot is in operation
- Know the location of and Verify that all safety and emergency devices are working properly
- NEVER fully rely on the correct operation of the software
- Do NOT assume that the robot has completed its task if it has stopped moving
- Do NOT assume the robot will follow any pre-program procedure
- NEVER attempt to block the robot's motion with your body
Robot Maintenance Safety Requirements
- Do NOT perform maintenance on a robot during operation
- Check for any hazardous conditions before entering the workcell
- Check for any unauthorized personal in the workcell first
- Wear appropriate clothing; avoid loose clothing, rings, watches, etc.
- Confirm the correct operation of the teach pendant
- Verify that all safety and emergency devices are functioning properly
- Perform maintenance with the power off, whenever possible
- Release all stored energy (air pressure, paint pressure, welding end of the arm tooling)
- Be cautious when removing a servomotor or brake
- Keep the workcell clean and organized
- Use specified parts for replacement only
- Review all safety requirements before restarting the robot
- Reinitialize all safety devices after maintenance completion
- Perform a test run on the robot at the end of maintenance
