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.

If your house was built before 1978 and you’re noticing cracking or peeling paint, a lead paint inspection is a good idea. A lead paint inspection gives you accurate information about the presence, location, and condition of lead-based paint in your home. This information is essential for making informed decisions about lead paint removal to ensure your safety and health and that of your family. If your inspector finds lead, you’ll need to take steps to manage or remove the lead-based paint and comply with laws and regulations.

Professional testing for lead paint costs about $300, ranging from about $250 to $700, depending on the square footage, accessibility, and location. However, testing for lead paint with a DIY home-testing kit costs about $25, but doesn’t guarantee accurate results. The U.S. Environmental Protection Agency (EPA) recommends using a lead test kit that complies with the Lead Renovation, Repair, and Painting (RRP) Rule, which has strict criteria for ensuring a more accurate reading.

Common home surfaces to test for lead include:

• Walls

• Windows

• Doors

• Molding and trim

• Railings

If lead is detected in a property, steps should include arranging for professional removal or containment, notifying all occupants, and implementing interim safety measures to reduce exposure.
