Asbestos is a substance that can be very dangerous and can result in a number of ill health effects through exposure to airborne dust and fibers from the asbestos. A Pennsylvania asbestos lawyer is a legal expert that can help anyone that has been exposed to asbestos and has suffered ill effects as a result of this exposure.
