,Q1. During a lead abatement project in a pre-1960 building, a supervisor observes that the containment area
has been breached by a worker exiting without proper decontamination. The air monitoring results from the
adjacent occupied space show a lead concentration of 25 µg/m³ (8-hour TWA). Given that the OSHA PEL for
lead is 50 µg/m³, which of the following actions is most appropriate?
A. Allow work to continue because the level is below the PEL.
B. Immediately halt work and initiate a full decontamination of the breached area.
C. Increase ventilation and continue monitoring; no further action required.
D. Report the breach to OSHA within 24 hours.
Correct Answer: B. Immediately halt work and initiate a full decontamination of the breached area.
Rationale: Even though the lead level is below the OSHA PEL, any breach of containment requires immediate
cessation of work to prevent further contamination and ensure worker and occupant safety. Full decontamination is
necessary to restore containment integrity. Continuing work or merely increasing ventilation does not address the
breach. OSHA reporting is not required for this level unless it results in a citation or injury.
Why Wrong:
A - The PEL is not a threshold for containment integrity; breaches must be corrected regardless of air levels.
C - Increased ventilation does not rectify the breach; the containment must be re-established.
D - OSHA does not require reporting of a breach without overexposure or injury.

Decontamination
Q2. A lead abatement supervisor is planning a project in a NYC building constructed in 1920. The building
has been identified as having lead-based paint on windows and doors. Which of the following best describes
the legal requirement for the use of a chemical stripper containing methylene chloride?
A. Methylene chloride is prohibited for any use in NYC lead abatement.
B. It may be used only if the building is a designated landmark.
C. It is allowed if the work area is ventilated and workers wear appropriate PPE.
D. It is banned for residential abatement but allowed in commercial settings.
Correct Answer: A. Methylene chloride is prohibited for any use in NYC lead abatement.
Rationale: Methylene chloride is prohibited for use in lead abatement in NYC due to its high toxicity and
carcinogenicity. The NYC Department of Health and Mental Hygiene bans its use in all abatement activities.
Ventilation and PPE do not mitigate the risk sufficiently for this chemical.
Why Wrong:
B - Landmark status does not permit the use of banned substances.
C - No level of ventilation or PPE is considered adequate for methylene chloride in abatement.
D - The ban applies to all settings, not just residential.

, Q3. A supervisor is reviewing a worker's blood lead level (BLL) results. The worker has a BLL of 35 µg/dL.
According to OSHA's Lead Standard for Construction (29 CFR 1926.62), which of the following actions is
mandatory?
A. Remove the worker from exposure until BLL falls below 25 µg/dL.
B. Provide a medical examination and offer temporary removal with medical removal protection benefits.
C. Notify the worker in writing and continue monitoring monthly.
D. Conduct a fit test for respirators and retrain the worker.
Correct Answer: B. Provide a medical examination and offer temporary removal with medical removal
protection benefits.
Rationale: OSHA requires medical removal when a worker's BLL exceeds 30 µg/dL (trigger level). The worker
must be provided with a medical examination and offered temporary removal with medical removal protection
benefits (MRP) including full pay and benefits until BLL drops below 25 µg/dL. Notification and monitoring are
insufficient; removal is mandatory.
Why Wrong:
A - The removal threshold is 30 µg/dL, not 25 µg/dL, and removal is mandatory at 35 µg/dL.
C - The BLL is above the trigger level, so removal is required, not just monitoring.
D - Fit testing and retraining are important but not the primary mandatory action for this BLL.
Reference: 29 CFR 1926.62: Lead Exposure in Construction; Medical Removal Protection
Q4. During a lead abatement project, a supervisor must select a HEPA vacuum for cleanup. Which of the
following specifications is critical to ensure compliance with EPA regulations for lead-contaminated dust?
A. The vacuum must have a HEPA filter with 99.97% efficiency at 0.3 microns.
B. The vacuum must have a HEPA filter with 95% efficiency at 0.3 microns.
C. The vacuum must be equipped with a high-efficiency particulate air (HEPA) filter that meets ISO Class 5
standards.
D. The vacuum must be a wet/dry type for both dry and wet cleanup.
Correct Answer: A. The vacuum must have a HEPA filter with 99.97% efficiency at 0.3 microns.
Rationale: EPA regulations require HEPA vacuums to have filters with 99.97% efficiency at 0.3 microns (the most
penetrating particle size). This is the standard for lead dust cleanup. ISO Class 5 is a cleanroom standard, not
directly applicable. Wet/dry capability is not a regulatory requirement.
Why Wrong:
B - 95% efficiency is insufficient; the standard is 99.97%.
C - ISO Class 5 refers to cleanroom air cleanliness, not vacuum filter efficiency.
D - Wet/dry capability is not mandated by EPA for lead abatement.
