Classes of machine safety
(OP)
I am looking for some documentation regarding classification of machine safety? Can anyone help me out, specifically how the classes break down.

RE: Classes of machine safety
ANSI/RIA R15.06-1999 contains a risk assessment procedure that is commonly used in North America.
ISO 13849-1 is commonly used in Europe although the outgoing standard, EN 954-1, was easier to understand.
Or if I misunderstood your vague question, please clarify?

RE: Classes of machine safety
But, having been through this many hundreds if not thousands of times, you are likely going to find that all but the most trivial risks are going to require dual channel circuits with safety relays, etc. You may have some risk combinations that allow a lower risk category, but all it takes is one combination that's guarded by the same guarding to require "control reliable" or "category 3" or "performance level d" to govern that the whole thing needs to meet that category or performance level or whatever you want to call it.
The low and decreasing cost of safety-related hardware these days usually isn't worth the aggravation and risk associated with trying to save a few pennies by cheaping out by using a lower risk category.

Plant safety must be approached in the broadest sense and then broken down to all the various activities where there is risk. You will need to understand what your hazards are, have mitigation plans to reduce the risks. You will then have to communicate the risks and train the people on how to properly do a function safely. You will also have to monitor and audit your safety program to know it is being used.

You can find a breakdown of the different classes of safety in NFPA 79. I don't have my copy in front of me, so I can't quote chapter and verse, but it is in there.
