7. Engineering ethics Set of behavioral standards engineers are expected to follow Set of behavioral standards engineers are expected to follow Engineers’ work has a direct and vital impact on quality of life for all people Engineers’ work has a direct and vital impact on quality of life for all people Services require honesty, impartiality, fairness and equity Services require honesty, impartiality, fairness and equity Dedicated to protection of public health, safety and welfare Dedicated to protection of public health, safety and welfare

8. NSPE Code of Ethics Adherence to the highest principles of ethical conduct on behalf of the public, clients, employers and the profession Adherence to the highest principles of ethical conduct on behalf of the public, clients, employers and the profession Engineers shall… Engineers shall… –Hold paramount the safety, health and welfare of the public in the performance of their professional duties –Perform services only in areas of competence –Issue public statements only in an objective and truthful manner –Act in professional manner for employer or client

9. NSPE Code of Ethics 1. Protect the public safety, health and welfare. 2. Perform duties only in areas of competence. 3. Be truthful and objective. 4. Behave in an honorable and dignified manner. 5. Continue learning to sharpen technical skills. 6. Provide honest hard work to employers or clients. 7. Inform the proper authorities of harmful, dangerous or illegal activities. 8. Be involved with civic and community affairs. 9. Protect the environment. 10. Do not accept bribes or gifts that interfere with engineering judgment. 11. Protect confidential information of employer or client. 12. Avoid conflicts of interest.
