Containment Setup & Waste Disposal Flashcards

What is the minimum polyethylene sheeting thickness required for interior containment under the EPA RRP Rule?

Answer: 6-mil polyethylene sheeting

The EPA RRP Rule and associated guidance recommend 6-mil polyethylene sheeting for interior containment to prevent lead dust migration.

For interior renovation work, how far should protective sheeting extend from the work area walls?

Answer: At least 6 feet in all directions from the work area

Interior containment sheeting must extend at least 6 feet in all directions from the work area to capture dust and debris.

Which of the following items must be covered or removed from an interior work area before renovation begins?

Answer: Furniture, carpets, and HVAC system vents

All furniture, floor coverings, and HVAC openings must be covered or removed to prevent lead dust contamination of those surfaces.

What is the purpose of sealing HVAC vents and returns during interior lead renovation work?

Answer: To prevent lead dust from spreading through the duct system to other areas of the building

Sealing HVAC vents prevents lead dust from being drawn into the duct system and distributed to unaffected areas of the building.

For exterior lead renovation work, when is additional warning signage and containment required?

Answer: When work could affect soil, water, or neighboring properties

Exterior containment must prevent lead dust and chips from contaminating soil, water, and areas beyond the property, including neighboring properties.

What should a renovator do if wind or weather conditions make exterior containment ineffective during a renovation?

Answer: Stop work until conditions improve or alternative containment can be established

If weather conditions compromise exterior containment effectiveness, work must stop to prevent uncontrolled lead dust dispersal.
