3. Intrinsic safety built into Robot design and operation
Hazard Analysis of the robot’s use, programming, work environment, human error and maintenance operations.
Encourages a combination of safeguarding methods using both redundant and back-up systems.

Safeguarding the Teacher
A restricted speed of 10 inches per second should be placed on any part of the robot during training to minimize injury to the teacher or programmer.
