📖 Verified core answer

Chlorine/humid pool air can destroy the wrong metal fast. Stop and verify the specified corrosion-resistant material before more work is covered.

Field verification checklist

Look for white rust, red rust, pitting, seam staining, or coating failure.
Confirm whether the duct is in supply, return, exhaust, or pool chemical air.
Check material schedule for stainless/aluminum/coated systems.
Verify fasteners and hangers are compatible too.
Hold cover until material direction is confirmed.

Ask foreman

The galvanized spiral at [pool/location] is already corroding in chlorine/humid air. I documented the seams and checked the material concern. Do you want this held for specified corrosion-resistant material?

Text to foreman

Route options

ACorrect it only if the fix is within your assignment and approved method.

BHold and document if it affects pressure class, listed assembly, material spec, support load path, fire barrier, equipment, TAB, or another trade.

CBring the foreman/detailer the location, what you checked, and what decision you need before sealing, testing, cover, or startup.

Do not do this

Do not leave standard galvanized duct in a corrosive pool environment if the spec calls for something else.

Why this matters

Wrong material in pool air can fail fast, leak, contaminate the system, and cause expensive replacement.

Final verification

Use this as field training guidance. Final direction still comes from the foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, pressure/material schedule, and AHJ/code requirements.
