What is it?
Asbestos is a group of minerals that occur naturally in some rocks and soil. It comes in long fibers that are strong and heat-resistant.
Asbestos has been used in insulation, fireproofing, and other building materials. It has also been used in heat-resistant coverings, fabrics, and gloves, and friction products such as automobile brakes.
Because of health concerns, all new uses of asbestos in the United States were banned in 1989.
Where is Asbestos found?
- Consumer products
- Prior to the early 1970’s- old building materials (old pipes, furnace insulation, wallboard, plaster, cement), heat-resistant fabrics
- Current uses - automobile parts (brakes, clutch facings), roofing materials, vinyl floor tile, cement pipes, and some talc
- Air - particles can be released by the breakdown or demolition of building materials; they can be released by mining and shipbuilding.
How can I be exposed to Asbestos?
Asbestos commonly enter(s) the body through:
- (infrequent pathway) - swallowing fibers or drinking water that contains asbestos
- (most frequent pathway with highest risk of illness) - breathing asbestos particles in the air
- (infrequent pathway) - touching particles or fibers; touching equipment or washing clothes that have been exposed to asbestos fibers
What happens when I am exposed to Asbestos?
Asbestos exposure to the general public and in the construction trades occurs less frequently than it did prior to the early 1970’s. Most occurrences of exposure today come from construction renovations and vehicle repair.
Breathing moderate to high amounts of varying sized particles of asbestos in the air can cause:
- Difficulty breathing
- Chest pain
Skin contact with asbestos particles can cause:
Breathing high levels of asbestos fibers for a long time can cause a number of lung-related conditions:
Who is at risk for exposure to Asbestos?
- Home remodeling and repair in older homes may release asbestos.
- Construction, shipbuilding, and demolition workers
- When older building and shipbuilding materials are broken down or moved, they may release asbestos.
- Families of workers exposed to asbestos
- Contaminated clothing and equipment can bring asbestos into the home.
Reduce your risk

- Are you planning any major maintenance, repairs, or remodeling in a home built before July 1989?
- Find out when your home was built. If your home was built before 1989, have a licensed contractor check for asbestos before you start repairs or remodeling.
- Hire a licensed contractor to properly remove and dispose of asbestos-containing materials.
- Never disturb asbestos-containing materials.
- Do not try to clean up asbestos-containing materials yourself.
