EPA Risk Assessor Exam (230
Questions)
1. What are 2 methods of paint removal not recommended by HUD?
● Dry scraping/sanding
● Methylene chloride paint strippers (can cause liver and kidney damage and
carbon monoxide poisoning)
2. What are 2 pros and 2 cons of encapsulation?
Pros:
● Lead dust is not generated
● May be less costly than some other abatement methods
Cons:
● Inappropriate for use on friction, impact, chewable, or severely deteriorated
surfaces
● Information on long-term durability is limited
3. What are 2 pros and 2 cons of off-site paint removal?
Pros:
● Low reevaluation failure rate
● Appropriate for historical preservation
Cons:
● Can be expensive
● May deteriorate glues or other elements of components which may cause
components to disintegrate
4. What are 2 pros and 2 cons of on-site paint removal?
Pro:
● Can be less costly than replacing or enclosing building components
Cons:
● Generates a lot of dust
, ● Hazardous waste generated
5. What are 2 pros and 2 cons of paint stabilization?
Pros:
● Cost is low
● Done by unskilled (but trained) workers
Cons:
● Not appropriate for severely damaged/unsound substrate
● Not appropriate for high wear areas where deterioration will likely occur
6. What are 2 pros and cons of building component replacement?
Pros:
● Permanent solution by removing all LBP
● Minimizes dust contamination of the property
Cons:
● Relatively expensive, especially for historic preservation projects
● Generate large amounts of waste which could be costly and complicated
7. What are 2 pros and cons of dust removal?
Pros:
● Doesn't require any specialized equipment except for HEPA vacuum
● Can be completed relatively quickly and effectively
Cons:
● Effective only if surfaces are smooth and cleanable
● Not effective for keeping dust levels below applicable standards over the
longer term if the source isn't controlled
8. What are 2 pros and cons of enclosure systems?
Pros:
● Allows using standard, locally available construction materials
● Highly reliable and more durable than encapsulation
Cons:
, ● Does not permanently remove LBP (only makes dwelling free of LBPH)
● Enclosures are vulnerable to water and physical damage
9. What are 2 pros and cons of friction/impact surface treatment?
Pros:
● Less costly than component replacement
● Dust generation is controlled with appropriate monitoring
Cons:
● Knowledge of construction techniques is required
● Extensive containment is needed to control dust generation for certain
procedures
10. What are 2 pros and cons of interim soil treatments? Pros:
● Lower initial investment than abatement
● Doesn't require specialized contractor skills or equipment
Cons:
● Requires continuous monitoring
● Barriers and covering can be easily disturbed or removed
11. What are 2 pros and cons of permanent covering of bare lead contaminated
soil?
Pros:
● Permanent solution to contaminated soil, provided the source of lead in the
soil has been controlled
● Doesn't generate waste
Cons:
● Not appropriate for certain land uses (backyards, sandboxes)
12. What are 2 pros and cons of removal and replacement of bare lead
contaminated soil?
Pros:
● Permanently removes the source of lead in soil by taking it off-site
Cons:
