Lead Abatement Methods & Techniques Flashcards

What does the term 'interim controls' mean under EPA lead regulations?

Answer: Temporary measures to reduce lead exposure while deferring abatement

Interim controls are temporary measures such as paint stabilization or specialized cleaning that reduce exposure but do not permanently eliminate the hazard.

Which condition makes encapsulation inappropriate as a long-term abatement strategy?

Answer: The existing paint is already peeling or deteriorating

Encapsulation fails when applied over deteriorating paint because the coating cannot bond properly, leading to future peeling and lead exposure.

What is the correct sequence for performing lead abatement in a room?

Answer: Set up containment, abate, clean, clearance testing

The correct order is containment setup first, then abatement, then cleaning, then clearance testing before occupants re-enter.

When replacing windows as a lead abatement strategy, what must happen to the old window components?

Answer: They must be disposed of as lead hazardous waste

Lead-painted components removed during abatement must be handled and disposed of as lead hazardous waste per federal and state regulations.

Which of the following best describes 'paint stabilization'?

Answer: Repairing the surface to stop paint from peeling and applying a protective coating

Paint stabilization involves fixing the underlying cause of deterioration and properly recoating the surface so the lead paint no longer peels or flakes.

Under EPA regulations, which surfaces are defined as 'impact surfaces' requiring special consideration during abatement?

Answer: Surfaces subject to damage from repeated striking, such as door stops and stair risers

Impact surfaces experience repeated physical contact that generates lead chips and dust, requiring abatement methods that permanently eliminate the hazard.
