The professional stamp or seal is a legally binding mark that signifies a professional has personally prepared, supervised, or thoroughly reviewed the document and accepts full legal and professional responsibility for its contents. "Rubber-stamping"—the act of sealing work created by someone else without conducting a comprehensive and detailed review—is a severe ethical and legal violation. If a professional technologist signs and seals drawings that were not produced under their direct supervision and without taking the time to thoroughly review the calculations, standards, and safety implications, they are giving a professional guarantee without actually verifying the facts. This explicitly violates the ethical principle requiring members to "provide an opinion on a professional subject only when it is founded upon adequate knowledge and honest conviction." Without direct supervision or rigorous retroactive review, the technologist lacks the "adequate knowledge" required to legally certify that the drawings are safe, compliant, and fit for purpose, thereby endangering the public and compromising professional integrity.
