Which of the following is part of a chemical engineer's duties?

• A. Report defective equipment
• B. Uphold the dignity of the profession
• C. Issue criticisms about private concerns
• D. Protect the client's interest

Answer: (A)

Reporting defective equipment is a fundamental duty because it directly safeguards safety, health, and the environment. In chemical engineering, equipment failures can cause leaks, explosions, toxic releases, or compromised product quality. When a defect is noticed, the engineer should document it, notify the appropriate authorities, and follow safe shutdown or isolation procedures and change-management processes to ensure timely repairs or replacement. This obligation aligns with professional codes that prioritize safety and public welfare above other considerations. The other options touch on professional conduct in a broad sense or involve competing interests, but they do not represent concrete duties that actively prevent harm or ensure safe operation.
