1.3.2. SAFETY DIRECTIVES CONCERNING TO THE WORK ENVIRONMENT
Analysis of safety around the robot cell
Safety must be taken into account for the robot cell from the design and development stage on.
Before planning the installation of the robot cell, it is necessary to study the following points:
• Plan the safety strategies that reduce risks to an acceptable level.
• Define the tasks required for the foreseeable applications and assess the access and/or approach
requirements.
• Identify the sources of risks including the failures and the failure modes associated with each of the tasks.
The risks can involve:
• the cell itself
• its association with other items of equipment
• the interactions between persons and the cell.
• Assess and estimate the risks stemming from cell operation:
• programming risks
• operating risks
• risks during use
• maintenance risks for the robot cell.
• Select the protective methods:
• use of protective devices
• installation of signalling means
• compliance with safe working procedures.
These points are taken from the standards applicable to robots, and especially European standard EN 775.
Note:
This list is not exhaustive. Above all, it is necessary to comply with the standards in force
in your country.
CAUTION:
To ensure reliability and precision in the robot's movements, the robot cell environment
must comply with the levels of disturbance set out in the safety standards.
