Lead Abatement Methods & Techniques Flashcards

During mechanical paint removal, which control measure is required to prevent dust dispersal?

Answer: Attaching HEPA-filtered vacuum systems to tools

HEPA-filtered vacuum attachments capture lead dust at the source during mechanical removal, preventing it from becoming airborne.

What minimum temperature restriction applies to heat gun use during lead paint removal to prevent lead fume generation?

Answer: Below 1,100°F

EPA regulations require heat guns to operate below 1,100°F because higher temperatures volatilize lead, creating dangerous airborne lead fumes.

Which abatement method is considered a 'permanent' solution under EPA regulations?

Answer: Paint removal down to bare substrate

Paint removal down to bare substrate is considered permanent abatement because it eliminates the lead-based paint source entirely.

Before starting abatement on a friction surface such as a window sill, what unique concern must be addressed?

Answer: Lead dust is generated continuously through normal use even after abatement

Friction surfaces generate lead dust through ongoing wear, so abatement must be permanent (removal or replacement) rather than encapsulation alone.

After lead paint abatement using chemical stripping, what must be done with the waste material?

Answer: It must be disposed of as hazardous waste per applicable regulations

Lead paint waste from chemical stripping contains lead compounds and must be managed as hazardous waste in accordance with federal and state regulations.

Which type of respirator is required for contractors performing dry abrasive blasting of lead-painted surfaces?

Answer: Supplied-air respirator (SAR)

Dry abrasive blasting generates extremely high concentrations of lead dust, requiring a supplied-air respirator to provide the highest level of respiratory protection.
