Which of the following can practice chemical engineering?

• A. Licensed and registered chemical engineers
• B. Industrial plants
• C. All BSChE graduates
• D. PIChE

Answer: (A)

Practice of chemical engineering is a regulated professional activity that requires licensure. Licensed and registered chemical engineers have met the formal requirements (education, experience, and the professional examination) and are legally authorized to perform engineering services for the public and to certify their work. Industrial plants are facilities, not individuals, so they don’t hold the authority to practice. Not all BSChE graduates are licensed to practice; licensure is separate from simply having a degree. PIChE is a professional society that supports engineers but does not grant the legal authority to practice. Therefore, the option that best fits “can practice chemical engineering” is the licensed and registered chemical engineers.
