Engineering ethics is the set of rules and guidelines that engineers must follow as a moral obligation. It is important for engineers to prioritize public safety and health above all else. When engineering ethics are not followed, it can result in disasters like building collapses or space shuttle accidents that endanger lives and result in financial losses. Adhering to principles of honesty, public safety, diligence and other ethical values helps engineers ensure safety, minimize losses, protect welfare, and build reliability and trust in their work.
