Pool or natatorium duct, supports, or hardware are exposed to corrosive air. What changes?

Treat pool/natatorium work as a corrosive-environment hold point. Confirm approved material, coating, fasteners, isolation, supports, and documentation before installing standard hardware.

Verify material, coating, fastener/support type, and dissimilar metal concerns before installing in corrosive environments.

Stop if

• This duct/support/hardware is in a pool/natatorium/corrosive area. Can you confirm the approved material, coating, and fastener/support type before I install standard hardware?

Watch out

• Do not assume normal galvanized hardware is acceptable in corrosive air. Do not mix metals/materials without project direction.

Check

• Space/environment
• Approved material/coating
• Fastener/support type
• Dissimilar metal contact
• Existing corrosion documentation

Steps

• Identify the space: pool, natatorium, aquatic center, chemical room, or corrosive exhaust area.
• Check approved drawings/specs/submittals for material and coating requirements.
• Verify fastener/support material before installing.
• Photograph existing corrosion or questionable material.
• Ask before mixing galvanized, stainless, coated, aluminum, or dissimilar metals.
