A method for risk assessment violation monitoring during a functional safety process includes receiving parameters from a risk assessment of a portion of a system with physical devices. The parameters of the risk assessment are applicable to a safety device of a machine safety system. The safety device is configured to prevent a hazardous condition in the system. The method includes detecting a change of a condition of the safety device. The condition is indicative of a potential safety issue affecting operation of the machine safety system. The method includes comparing parameters related to the change of the condition of the safety device with the parameters from the risk assessment and sending an alert in response to determining that the change of the condition of the safety device results in a violation of the risk assessment.
