Wastewater Treatment Corrosion Air

Wastewater areas can have corrosive gases, high humidity, and special coatings/materials.

Stop if

• This area has wastewater/corrosive air. What material, coating, and fastener requirements apply?

Watch out

• Do not use standard hardware/coating assumptions in corrosive wastewater zones.

Check

• Confirm corrosion class, material/coating, fasteners, supports, drains, and odor-control equipment.

Steps

• Identify whether this is normal ductwork or a controlled/special condition.
• Confirm corrosion class, material/coating, fasteners, supports, drains, and odor-control equipment.
• Get the current drawing/detail/spec/submittal before changing routing, material, access, or support.
• Bring photos, location, and what you checked to the foreman before closing or covering the work.
