• A. Ensuring safety, compliance, proper operation, regular maintenance, and emergency preparedness.
• B. Marketing and sales.
• C. Designing new products only.
• D. Financial auditing.

Answer: (A)

The main idea is that B-28/W-28 holders are responsible for safety, compliance, proper operation, regular maintenance, and emergency preparedness of flammable-refrigerant systems. This means ensuring the equipment operates within its design parameters, following applicable codes and standards, and overseeing or performing routine maintenance and inspections. It includes conducting leak checks, proper refrigerant handling and recovery, and maintaining readiness for emergencies through trained personnel and documented procedures. Keeping thorough records of maintenance, inspections, tests, and training is also part of the role, along with coordinating with building management and authorities during incidents. Activities like marketing, product design, or financial auditing aren’t within the scope of this certificate.
