The primary ethical responsibility of engineers is to protect the safety and well-being of the public. This means that engineers must always consider the potential consequences of their work and take steps to minimize any risks to the public.

Impartiality is the ethical principle that engineers should avoid conflicts of interest. This means that engineers should not allow their personal or financial interests to influence their professional judgment.

Engineers must always consider the safety of their designs and products. This includes ensuring that buildings are structurally sound, that products are safe to use, and that projects do not pose any safety risks to the public.

Autonomy is the ethical principle that engineers should respect the autonomy of their clients. This means that engineers should allow their clients to make their own decisions about the design and implementation of projects, as long as those decisions do not pose any safety risks or violate any ethical principles.

Engineers must always consider the environmental impact of their designs and products. This includes assessing the potential for a project to pollute the air, water, or land, and taking steps to minimize any negative environmental impacts.

Justice is the ethical principle that engineers should strive to promote social justice. This means that engineers should work to ensure that their designs and products are accessible to all people, regardless of their race, gender, socioeconomic status, or other factors.

Engineers have a responsibility to protect the environment, promote social justice, and ensure the safety of their designs and products. These responsibilities are all part of the ethical code that engineers are expected to uphold.

Integrity is the ethical principle that engineers should be honest and transparent in their dealings with clients and colleagues. This means that engineers should always be truthful and accurate in their representations, and that they should avoid any conflicts of interest.

A conflict of interest arises when an engineer's personal or financial interests conflict with their professional responsibilities. In the given situation, the engineer is being offered a bribe to approve a design that does not meet safety standards. This is a clear conflict of interest, as the engineer's personal financial gain is being put ahead of their professional responsibility to protect the safety of the public.

Accountability is the ethical principle that engineers should be accountable for their work. This means that engineers should be willing to take responsibility for any mistakes or errors that they make, and that they should be open to criticism and feedback from others.

Engineers can be held accountable for their work in a variety of situations. Some examples include when they design a product or structure that fails, when they approve a product that is later found to be defective, or when they fail to properly maintain a piece of equipment. In these situations, engineers may be held liable for any damages or injuries that result from their negligence or misconduct.

Professionalism is the ethical principle that engineers should be committed to lifelong learning and professional development. This means that engineers should always be striving to improve their knowledge and skills, and that they should be open to new ideas and technologies.

Professionalism is demonstrated by engineers who are committed to lifelong learning and professional development. This can be shown through attending conferences and workshops, reading industry journals and articles, participating in continuing education courses, and other activities that help engineers to stay up-to-date on the latest developments in their field.

Respect is the ethical principle that engineers should be respectful of the rights and dignity of others. This means that engineers should always treat others with respect, regardless of their race, gender, socioeconomic status, or other factors.

Respect is demonstrated by engineers who are willing to listen to the concerns of others, treat their colleagues with respect, and compromise to reach mutually agreeable solutions. These actions show that engineers value the rights and dignity of others.
