When you bypass something for maintenance, you’re removing a safety feature from the system temporarily. To manage that risk, the bypass must be kept sealed and clearly labeled, and it should be opened only during authorized maintenance and testing. This approach prevents accidental tampering, makes the status of the system obvious to everyone, and ensures there’s proper control and documentation for when the bypass is enabled and when it’s re-enabled to normal operation. Leaving a bypass open for quick testing or treating labeling as optional would undermine safety and could lead to unanticipated reactivation of unsafe conditions. So the best precaution is to keep the bypass sealed with clear labeling and restrict opening to authorized maintenance and testing.
