The escape board is near to essential when it comes time to harvest the honey. It allows bees who are in the upper bee-boxes to descend into the brood box without letting them return to the honey boxes.
To use it, you remove the queen extractor and install the escape board under the bee box, with the maze face down. Then, 48 hours after installation, you can retrieve your honey frames in peace. If there are still a few bees in the honey frames, brush them off gently with the bee brush.
