What is the ethical guideline for engineers regarding their level of expertise?

The ethical guideline for engineers regarding their level of expertise emphasizes that they should only work within their known area of expertise. This principle is grounded in the importance of ensuring public safety and maintaining the integrity of the profession. By limiting their practice to areas where they possess the necessary knowledge and skills, engineers help ensure that their work meets the required standards of quality and safety.

This guideline mitigates the risk of errors that could arise from inadequate knowledge or experience and underscores the responsibility engineers have to their clients, the public, and the profession as a whole. It encourages professionals to understand their limitations and seek help or consulting when faced with unfamiliar challenges, thus upholding ethical standards and promoting competent practice within engineering disciplines.

This principle also helps to promote trust in the engineering profession; clients and the public can be assured that engineers are qualified to perform their tasks effectively. While expanding expertise is undoubtedly important, it should not come at the expense of competence in specific projects.
