The duty of the chemical engineer includes all of the following except?

• A. Uphold the dignity
• B. Report defective equipment and the danger concerning chemicals
• C. Protect the interest of his client
• D. Issue criticisms and statements on matters of public concern paid for by private interests

Answer: (D)

The main idea is that a chemical engineer’s duties center on public safety, professional integrity, and responsible practice. Upholding the dignity of the profession means acting honestly, maintaining competence, and earning society’s trust. Reporting defective equipment and the dangers of chemicals is a direct safety obligation—it helps prevent harm to workers, the public, and the environment. Protecting the client’s interests is also a duty, provided it does not compromise safety or ethics; engineers must represent their client’s legitimate interests while still prioritizing safety and regulatory compliance. The statement about issuing criticisms and public statements paid for by private interests does not fit as a duty because it introduces a financial incentive that can bias judgment and erode independence. Public reporting and advocacy should be based on honest, independent assessment, not on paid influence.
