Sharp saw blades and nail-studded 2x4s are obvious home-remodeling hazards. But other dangers aren't as easy to spot. For example, lead dust and asbestos fibers, often kicked up into the air when old walls come down, can settle on everything from doorknobs to the dinner table.
Here are five serious contaminants associated with common building materials, along with what you can do to protect yourself and your family, and several safer alternatives. Whatever the task, seal off work areas from the rest of the home and wipe down and air out the entire house once the job is done. Also consider temporarily relocating during messy or lengthy projects.
ARSENIC
What it is. A carcinogenic heavy metal known to cause everything from contact dermatitis and diarrhea to kidney damage.
Where it is. In pressure-treated wood preserved with chromated copper arsenate (CCA), which was used before 2004 to construct residential decks, foundations, and play sets. The arsenic in this wood can leach into the soil. (Arsenic may also be found in soil contaminated by since-banned rat poisons and weed killers.)
