Risk Assessment - Omron Techman Robot Safety Manual

• Use without safe access to (or at/from) the work station
• Use in the presence of exhaust gases/lack of oxygen at the work position
• Use in the presence of flame (flammability of the cabinet, lack of extinguishing means)
• Use with mechanical hazards at the work position: a) rollover; b) fall of objects, penetration by objects; c)
break-up of parts moving at high speed; d) contact of persons with machine parts or tools (non-collaborative
machines)
• Use with insufficient visibility from the work positions
• Use with inadequate lighting
• Use with inadequate seating
• Use with insufficient means for escape or entrapment avoidance
• Use with inadequate location of manual controls
• Use with inadequate design of manual controls and their mode of operation

Risk Assessment

Before installing and using this product, the user must first perform a risk assessments based on the conditions of
use. Risk assessments can be in reference to the specifications of ISO 10218-2, ISO 12100 and ISO/TS 15066
documentations. The purpose of a risk assessment is to anticipate any accidents that may occur during the
operation process and by means of appropriate protective measures to reduce the occurrence of accidents or to
reduce the severity of injury to persons in the event of an accident. Therefore, the risk assessment needs to include
any operational actions of the machinery within the scope of the assessment. After the risk assessment is
completed, the user can use external related components (i.e. sensing components, emergency stop devices,
fences or railings, etc.) as well as the parameter settings of safety functions in the operating system, to reduce
possible occurrence of accidents. Additional safety-related components must be installed in accordance with the
manufacturer's specifications for the required risk reduction. For operating system safety settings and other safety
components usage, read and understand this manual, the Software Manual and the Hardware Installation Manual
of corresponding versions.
Potential hazards requiring additional risk reduction measures may include but are not limited to:
1. Finger(s) (especially in the case of hand guiding) caught between the rear end of the camera module and the
joint module(s).
2. The palm or finger injured by the motion of the robot or the hand guide teaching, if caught between the robot
end-effector (including the workpiece) and the robot body.
3. Being hit by a robot and injured.
4. Entrapment between a robot and a fixed surface.
5. Incorrect human-robot collaborative workspace setup, parameter settings or project operation.
6. TCP force may be estimated incorrectly when robot is passing the area near singularity point in space, due to
