What to Check First

Confirm the final system designation
Verify airflow direction in the completed run
Check label wording, size, color, and spacing requirements
Keep labels visible after insulation and ceiling work
Correct labels when routing or system names change

Ask Foreman

Can you confirm the final system name and airflow direction before I place these permanent labels?

Do Not Do This

Do not copy old plan labels after routing changes or place arrows where the final airflow has not been verified.

Why This Matters

Wrong labels waste service time and can cause dangerous mistakes on exhaust, outside-air, or life-safety systems.

Verify against: project identification specification, approved drawings, as-built markups.
