. Behavior is the consideration given to the impacts that certain engineer’s way of doing things would have on the public, clients, employer or the profession itself (Johnson 1991). So behavior ethics require that the way in which engineers behave do not negatively impact on the health, safety and well being of the public, clients, employer or profession (Johnson 1991). Therefore it involves sticking to the set code of professional ethics, while integrating positive logical reasoning, in the process of delivering their services or products. The origins of some major ethics are the early scholars, professional organizations, society bodies, government departments, civil organizations and research bodies among others. This can be supported by publications of Thomas Percival on professional ethics in 1740-1804 followed with adoption of first engineering code of ethics in 1912-1914 by AIEE and ASME (FANG 2009).
