Abstract
System(s) and method(s) that facilitate utilizing biometric sensors (e.g., fingerprint, hand scan, voice recognition . . . ) in manufacturing systems in order to maintain accurate safety audit trails. A safety audit system, utilizing a biometric sensing device, facilitates determining if a user is allowed to access and change the configuration of the manufacturing system. Once a user is allowed to change the configuration (e.g., programmable electronics, tooling changes, software updates, etc.) the changes are automatically recorded in a safety audit database. Automatic storage of configuration changes mitigates manual recording of changes thereby enhancing the safety audit data often necessary to meet safety standards for manufacturing systems.
