Why is it important to document changes to a B28 system?

• A. To maintain an accurate safety assessment and ensure ongoing compliance with updated codes and equipment
• B. To improve marketing materials
• C. To increase downtime reported
• D. To assign blame for failures

Answer: (A)

Documenting changes to a B28 system keeps the safety assessment accurate and ensures the installation stays in step with current codes and equipment. When modifications are made—such as changing refrigerants, altering piping, updating ventilation or detection, or adjusting controls—the safety analysis must be updated to reflect new hazards, required clearances, evacuation procedures, and response plans. This provides anyone reviewing the system with a true picture of its configuration, supports ongoing regulatory compliance, and helps ensure proper maintenance and safe operation. It’s about safety and compliance, not marketing, downtime claims, or assigning blame.
