When equipment changes are made, which actions must be carried out for permit renewals in a B28 system?

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

Answer: (A)

When equipment changes are made in a B28 flammable-refrigerant system, the permit renewal must address four linked actions because new equipment can alter hazards and how the system is operated. Reassessing risk ensures the hazard evaluation reflects the updated configuration, including potential ignition sources, leaks, ventilation needs, and the effectiveness of existing controls. Updating procedures makes sure the operating steps, safety checks, interlocks, detection, isolation, and emergency actions match the new equipment. Retraining personnel confirms they understand the new hazards and the revised procedures, reducing human error. Updating the permit itself ensures the official authorization accurately describes the current system and controls, which is essential for regulatory compliance and inspections.

Skipping any of these steps creates mismatches between the actual system and the documented controls, procedures, training, or authorization, which can compromise safety and compliance.
