According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

You can sell a house with lead paint, but there are several requirements. If you are aware that lead paint exists anywhere in the home, you must disclose that to potential buyers. Required home inspections will often uncover lead paint, especially for older houses where lead paint may still be a problem. If you have taken steps to encapsulate lead, you should provide buyers with full documentation of the project so it won’t cause any problems later on.

While the EPA provides guidelines for homeowners to perform DIY lead paint removal, it is a risky process and generally not recommended due to serious health risks and strict regulatory requirements. The process requires precise safety precautions, such as wearing a respirator and protective eyeglasses, creating sealed exits, and using a HEPA vacuum for cleanup. To ensure the job is done safely, effectively, and in compliance with regulations, it is highly recommended to hire a professional lead abatement company. Certified professionals have the necessary training, experience, and specialized equipment (like chemical strippers and HEPA vacuums) to handle and dispose of hazardous materials safely.

The best way to remove lead paint is by wet hand sanding and removing all dust and residue with a HEPA vacuum. Professionals may also strip and scrape lead-based paint with a paint scraper. In some cases, you may choose to have a pro encapsulate or enclose your lead-based paint surface by covering it with a sealant or a new material. You may also choose to replace the material altogether.
