Which set of actions correctly reflects how to handle permit renewals or changes in equipment for a B28 system?

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

Answer: (A)

When a permit is renewed or the equipment is changed on a B28 flammable-refrigerant refrigeration system, you start by reassessing risk. New or altered equipment can introduce different ignition sources, leaks, ventilation needs, or operational hazards, so identifying those risks first is essential to know what controls are actually required.

Next, you update the procedures to reflect the new setup and any new risk controls. Written procedures should match how the system is now designed and operated, ensuring everyone follows the same, correct steps.

Then you retrain personnel on the updated procedures and hazard controls. Training solidifies understanding of the new equipment, the revised safety measures, and the proper response if something goes wrong.

Finally, you update the permits to reflect the current hardware, procedures, and training requirements. Keeping the permit documentation accurate ensures regulatory compliance and that inspections and approvals stay aligned with the actual system.

Other sequences skip or reorder essential steps, which can leave hazards unaddressed, procedures outdated, or personnel uninformed. The chosen order ensures risk is understood, controls are defined, staff are prepared, and the permit accurately represents the real, operating system.
