COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
Exam Coverage Summary
1. Lead hazards and health effects — Understand how lead exposure occurs, why lead is
dangerous, and the short- and long-term health effects on workers and occupants.
2. Ohio lead abatement regulations — Review Ohio-specific requirements governing lead
abatement activities, worker responsibilities, and regulated lead activities.
3. Lead-safe work practices — Know how to minimize lead dust generation during
abatement and prevent contamination from spreading.
4. Personal protective equipment (PPE) — Understand proper selection, use,
maintenance, and limitations of respirators, protective clothing, gloves, and other PPE.
5. Respiratory protection — Know fit testing, medical evaluation, respirator use,
limitations, cleaning, storage, and applicable work practices.
6. Containment and work-area setup — Understand critical barriers, isolation methods,
warning signs, access controls, and protection of occupants and adjacent areas.
7. Lead hazard control methods — Recognize appropriate approaches such as removal,
enclosure, encapsulation, replacement, and component treatment.
8. Decontamination and cleanup — Understand personal decontamination, equipment
cleaning, HEPA vacuuming, wet cleaning, and prevention of cross-contamination.
9. Waste handling and disposal — Know how to collect, contain, label, transport, and
dispose of lead-contaminated waste in accordance with applicable requirements.
10. Clearance and post-abatement procedures — Understand visual inspection, dust
clearance concepts, documentation, final cleanup, and responsibilities before an abated
area is returned to normal use.
,1. Which statement best explains why lead-based paint hazards are
especially concerning during renovation and abatement activities in older
residential properties?
A. Lead paint becomes harmless when covered by newer paint
B. Disturbing painted surfaces can generate lead-containing dust and debris
that can be inhaled or ingested
C. Lead hazards exist only when paint is visibly peeling
D. Lead exposure occurs only through direct skin absorption
Answer: B
Rationale: Disturbing lead-containing coatings can create hazardous dust
and debris. These particles may be inhaled or swallowed, making renovation
and abatement activities important sources of potential exposure.
2. What is the primary reason a lead abatement worker should avoid dry
sanding or dry scraping lead-based paint whenever prohibited or not
specifically controlled?
A. It makes the paint harder to remove
B. It creates excessive lead-containing dust that can become airborne
C. It permanently damages all painted surfaces
D. It prevents the use of protective clothing
Answer: B
Rationale: Dry sanding and uncontrolled dry scraping can generate
significant airborne lead dust. Appropriate lead-safe methods are used to
reduce dust generation and worker exposure.
,3. A worker enters a properly contained lead abatement work area and
notices that the critical barrier has become detached. What should the
worker do first?
A. Continue working until the end of the shift
B. Immediately report or correct the breach according to the work plan and
site procedures
C. Remove all PPE and leave through the nearest opening
D. Ignore the condition if no dust is visible
Answer: B
Rationale: A compromised containment system can allow lead dust to
migrate into occupied or uncontrolled areas. The condition must be
addressed promptly according to established procedures.
4. Which route of exposure is generally considered most important when
workers perform activities that generate airborne lead-containing dust?
A. Inhalation
B. Hearing
C. Skin coloration
D. Visual exposure
Answer: A
Rationale: Inhalation of airborne lead dust is a major occupational exposure
route. Lead can also be swallowed after contaminated hands or surfaces
contact food, beverages, or the mouth.
, 5. Why is handwashing particularly important for workers performing lead
abatement activities?
A. It removes all lead from the entire work area
B. It reduces the possibility of transferring lead contamination to the mouth
or uncontaminated areas
C. It eliminates the need for respiratory protection
D. It replaces the need for work-area containment
Answer: B
Rationale: Proper handwashing helps prevent ingestion of lead and reduces
the transfer of contamination outside controlled areas.
6. Which practice is most appropriate for preventing workers from carrying
lead dust home on their clothing?
A. Wearing contaminated work clothing home only once per week
B. Following established changing, decontamination, and clothing-handling
procedures
C. Brushing contaminated clothing with a dry household broom
D. Shaking dusty clothing outdoors before entering the home
Answer: B
Rationale: Proper decontamination and clothing management help prevent
take-home lead exposure. Contaminated clothing should be handled
according to applicable occupational and site procedures.
7. What is the primary purpose of a HEPA-filtered vacuum during lead
abatement cleanup?
