2.3
Improper use
DANGER
Hazard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of non-
observance.
The safety laser scanner and the primary protective device function as indirect protec‐
tive measures and cannot provide protection from pieces thrown out, emitted radiation,
electric voltage or similar. Transparent objects are not detected.
b
Take additional measures if necessary to provide protection against hazards that
do not result from movement of the robot arm.
In addition to the intended use, the manufacturer of the machine must also take haz‐
ards into account in the risk assessment that can occur due to reasonably foreseeable
misuse.
Foreseeable misuse by users
•
Users take chairs, ladders or similar into the protective field of the safety laser
scanner
•
Users take transparent objects into the hazardous area
•
Users jump over the scan plane of the safety laser scanner
WARNING
There is an increased residual risk in the event of misuse. If the protective field of the
primary protective device and the protective field of the safety laser scanner are clear,
the robot can move. In this case, the movement of the robot is not prevented by this
safety system.
The manufacturer and operator must be aware of this residual risk and bear the
responsibility for it.
2.4
Identifying hazards
This safety system is intended to reduce mechanical hazards in accordance with ISO
10218-1 while the robot is performing its task. This document considers the following
risks:
Mechanical hazards
•
Crushing
•
Cutting
•
Impact
Dangers posed generally by the robot’s task, the robot arm or the end effector of the
robot must also be considered by the manufacturer. If necessary, further measures
must be taken to minimize the resulting risks.
NOTE
Risks must be reduced or eliminated by design measures or replacement, and then by
protection and other additional technical measures. Residual risks must be retroac‐
tively reduced by other means such as warning signs, training, processes, etc.
Other residual risks, e.g., due to small parts being propelled, are not considered and
must be considered in detail in the risk assessment,
