When a surface that contains lead dust is disturbed, the dust can float about in the air for roughly an hour before settling again. Since you cannot see the dust, it is important always to wear protective gear when working with any materials that may contain lead paint and to keep children, pets, and others away from the area for as long as possible

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 home was built before 1978, there’s a chance that any paint on your hardwood floors could be lead paint—especially if it was already there when you moved in. Because lead is toxic, hiring a licensed pro to remove it is mandatory. The average price for professional lead paint removal ranges from $1,500 to $5,300 and depends on the scope of the project.

The safest way to remove lead-based paint is by letting a professional take over. For most people, lead paint removal costs an average of $3,400. You should never attempt to dry sand old lead-based paint surfaces by hand. Most professionals use a paint stripper to do the job followed by wet scraping, but if you don’t want to remove lead paint, another option is to paint over it. Only consider this option if the old lead paint finish isn’t flaking or cracked.
