Abstract
A method includes sending a first safety instruction to a machine in response to, within an entry window of time, receiving an open alert that a movable barrier is in an open state, where the movable barrier is at an entry point of an enclosure protecting personnel from the machine, receiving tag information of a person from a reader at the movable barrier, and confirming that the tag information belongs to a person authorized to enter the enclosure. The method includes sending a second safety instruction to the machine in response to, within the entry window of time, receiving the open alert, and without receiving tag information or confirming that the tag information belongs to a person authorized to enter the enclosure. The first and second safety instructions are different and the first safety instruction is less restrictive than the second safety instruction in terms of actions to prevent injury.
