balance between safety and productivity, in activities such as operation
and maintenance.
Then we continue with the design and verification. For this step, the
recommendation is to use ANSI B11.19 for North America and the
international standard ISO 13849-1, this international standard
guarantees the most up-to-date requirements for machinery safety
design, also software tools such as SISTEMA, developed by IFA in
Germany, helps us verify the safety solution before investing on safety
devices.
We continue with the Installation and Validation step. In this step, we
recommend to follow the manufacturer's installation instructions of the
safety devices, remember, a safety device is a device designed,
manufactured and certified to safeguard the integrity of the operator.
These components have safe failure modes, unlike standard industrial
control devices, which can fail in a non-safe way making it very difficult
to have proper safety and reliability just by using standard control
components. After the solution is installed, the validation process must
be done according to the requirements of ISO 13849-2.
Maintenance is also essential for the machine safety solution, to
maintain these systems accordingly we recommend following the
guidelines from the upcoming ANSI TR8 (Guide to Sustainable Safety
Systems through Inspection of Risk Reduction Measures) where not only
maintenance is covered but also the proper management of change
when any modification is necessary, whether is an equipment or
program modification.
Finally, once the machine has reached its production lifetime, a risk
analysis should be performed in order to decommission the machine as
safely as possible.
All the steps outlined in this document should follow the FSM
(Functional Safety Management from IEC 62061) to ensure that the
machine safety solution will safeguard the integrity of the personnel
who interact with any sort of manufacturing machine.
