Modbus Safe / ModSafe?

As I understand it Modbus is not suitable for use in safety related systems. I have heard a mention of Modbus Safe / ModSafe (whether the same thing I don't know) but am unable to find any literature on either topic. Could some one possibly point me in the right direction or give an explanation of how these work. Are they an overlay to standard modbus and will therefore work with standard modbus modules? Are standard FB's required? What makes the protocols safe compared to standard modbus? Thanks!
