1.4 Potential risk

In the risk assessment of an integrated robot system, if the assessment result indicates that risk factors are not sufficiently removed only by the robot’s safety functions, additional protective measures must be established.

In establishing additional protective measures, the following should be considered:

• Finger pinching (entanglement) between the robot base and the installation support during installation

• Injuries (such as poking and piercing) caused by sharp edges or protruding parts of obstacles or tools in the operating area

• Injuries caused by collision with the robot (such as bruises, falling, and bone fractures)

• Injuries caused by obstacles around the robot (such as poking, piercing, and bone fractures)

• Injuries caused by loose connections

• Injuries caused by toxic or hazardous substances under work (such as skin damage and breathing disorders)

• Displacement of objects under work caused by abrupt power shutoffs

• Erroneous activation of emergency stop switches caused by confusion with those of other equipment

• Errors caused by arbitrary modification of the Set up of safety functions

Because the types of potential risks vary depending on system compositions, a risk assessment must be carried out before using an integrated robot system.
