General Safety Information

Contact Rockwell Automation to learn more about our safety risk assessment services.
IMPORTANT
This application example is for advanced users and assumes that you are trained and experienced in safety system requirements.
ATTENTION: Perform a risk assessment to make sure that all task and hazard combinations have been identified and addressed. The risk assessment can require
additional circuitry to reduce the risk to a tolerable level. Safety circuits must consider safety distance calculations, which are not part of the scope of this
document.
Safety Distance Calculations
ATTENTION: While safety distance or access time calculations are beyond the scope of this document, compliant safety circuits must often consider a safety
distance or access time calculation.
Non-separating safeguards provide no physical barrier to prevent access to a hazard. Publications that offer guidance for
calculating compliant safety distances for safety systems that use non-separating safeguards, such as light curtains,
scanners, two-hand controls, or safety mats, include the following:
EN ISO 13855:2010 (Safety of Machinery – Positioning of safeguards with respect to the approach speeds of
parts of the human body)
EN ISO 13857:2008 (Safety of Machinery – Safety distances to prevent hazardous zones being reached by upper
and lower limbs)
ANSI B11:19 2010 (Machines – Performance Criteria for Safeguarding)
Door Locking and Monitoring with a 442G Access Box and an Integrated Safety Controller Safety Function
