For a B28 system, which option correctly describes the required actions for permit renewals or changes?

• A. Reassess risk, update procedures, retrain personnel, and update permits to reflect changes.
• B. Reassess risk, update permits to reflect changes
• C. Retrain personnel, update procedures
• D. Update permits to reflect changes, retrain personnel, and update procedures.

Answer: (A)

When a permit is renewed or the system changes, you must re-evaluate the risks, adjust how you operate, train the crew on those changes, and update the official permit to reflect them. Reassessing risk catches any new hazards or changed exposure from modifications, new equipment, or different refrigerants. Updating procedures makes sure the documented steps match the current setup and controls. Retraining guarantees personnel know and can safely execute the new procedures and respond correctly to hazards. Updating permits provides an official record showing the system’s current configuration and safety requirements. Skipping any part leaves a gap between what’s allowed on paper and what’s actually in place, which is why all four actions are required.
