📖 Verified core answer

A wet sound attenuator is not just dirty material; the media can lose performance and create mold risk. Hold it, document it, and get replacement or manufacturer direction.

Field verification checklist

Check delivery/storage condition before lifting the attenuator.
Look for water inside casing, wet media, damaged liner, rust, odor, or sagging baffles.
Document with photos and tag number.
Keep it out of the air system until accepted by foreman/manufacturer/spec.
Protect replacement material from weather before install.

Ask foreman

The sound attenuator for [location/tag] got soaked before install. I checked the casing/media and documented it. Do you want this rejected/replaced or held for manufacturer direction?

Text to foreman

Route options

AMake the field correction only if it is within your assignment and the approved method.

BHold and document the condition if the fix affects airflow, access, life safety, pressure class, rated assemblies, equipment, or another trade.

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

Do not do this

Do not install soaked acoustic equipment and hope airflow dries it out later.

Why this matters

Wet acoustic media can fail performance, contaminate the supply airstream, and create costly replacement after the duct is already installed.

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, and AHJ/code requirements.
