Which color tag would you expect on equipment that must be kept inoperative until a fault is corrected?

Red tags mean Do Not Operate: the equipment must be kept out of service until the fault is fixed. This color is used because it’s a clear, immediate signal that something is wrong and the device should not be used, protecting people from injury and preventing further damage. The tag stays with the equipment and is removed only after the fault is repaired and the unit is verified safe to run again. Other colors serve different statuses—green typically means the equipment is safe to operate, while orange and yellow indicate caution or maintenance conditions that don’t strictly require keeping the gear out of service.
