_Safety | Potential risks
Hyundai Robotics
In composing robot systems, if risk factors (e.g.: use of tools unintended for collaborative robots) are not sufficiently
removed by the robot’s safety functions, the necessity for additional protective devices can be identified in the risk
assessment.
1.4
Potential risks
In the risk assessment of a robot integrated 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) due to sharp edges or protruding parts of obstacles or tools in the
operating area
Injuries due to collision with the robot (such as bruises, falling, bone fractures)
Injuries due to obstacles around the robot (such as poking, piercing, and bone fractures)
Injuries due to loose connections
Injuries due to toxic or hazardous substances under work (such as skin damages, and breathing disorders)
Displacement of objects under work due to abrupt power shut-offs
Erroneous activation of emergency stop switches due to confusion with those of other equipment
Errors due to arbitrary modification of the settings of safety functions
Because the types of potential risks vary depending on system compositions, risk assessment must be carried out
before using a robot integrated system.
1.5
Validity and responsibilities
The user should conform to the safety requirements specified in the safety laws and regulations of the country and
locality in which the robot is installed and used. Responsibilities of suppliers and users of robot integrated systems
include but are not limited to the following:
Risk assessment of robot integrated systems
Addition or removal of safety devices according to the result of risk assessment
Checking that robot integrated systems are properly composed, installed and set
Establishment of the methods and instructions for using robot integrated systems, and provision of user training
Management of safety devices (prohibition of users from arbitrary modification and manipulation of safety
devices)
Provision of important pieces of information, contact addresses and the like relating to product use and safety
Provision of all types of technical documents including manuals
The safety-related content of this manual does not cover all the risk factors and situations that may occur during
product use.
