Unit 21 Key Point Review

Asbestos and Encapsulation

Asbestos was widely used in construction materials before its prohibition in 1978 due to serious health risks.
Health Impact: Can cause serious respiratory diseases when airborne fibers are inhaled.
Identification of asbestos-containing materials (ACMs) requires certified inspections.
Removal and Encapsulation: Removal is often costly; encapsulation can serve as a viable alternative to manage asbestos safely.

Lead-Based Paint

Lead-based paint regulations were established by the Lead-Based Paint Hazard Reduction Act (LBPHRA).
Exposure to lead is particularly dangerous for children and can lead to severe health issues.
Mandatory disclosure of lead hazards to potential buyers or renters is required; sellers must provide a risk assessment opportunity to buyers.

Radon

Radon is a radioactive gas that significantly increases lung cancer risks.
Classified as a human carcinogen, with no safe exposure level determined.
The EPA recommends action when radon concentrations exceed 4 pCi/L.
Knowledge of testing methods and mitigation systems for radon is essential for real estate professionals.

Carbon Monoxide

Carbon monoxide (CO) is a byproduct of fuel combustion, posing severe health risks without proper ventilation.
Critical to have CO detectors; many states mandate their installation in residential properties.

Mold

Mold growth results from moisture and high humidity, capable of generating health issues and property damage.
Insurance policies frequently exclude mold-related damages, complicating liability aspects.

Underground Storage Tanks and CERCLA

Underground Storage Tanks (USTs) are common in commercial and residential properties for storing oil and require meticulous management under federal law (RCRA).
Responsibilities encompass registration and adherence to regulations concerning installation and monitoring.
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund, identifies responsible parties for hazardous waste site cleanup and lays out various liability rules for property owners.
