Lead based paint presents a threat and is likely to be found in all residential/commercial buildings built before 1978. Although children are the most vulnerable to lead poisoning, lead also presents a threat to workers preforming renovations that disturb the paint as well as to residents of the renovated space. The deterioration of this paint results in elevated levels of lead-contaminated dust which can be inhaled or ingested (particularly by children). Over time, continued exposure can result in lead (heavy metal) poisoning and can cause serious health issues.
Asbestos is a fibrous mineral that occurs in rock and soil. Because of its fiber strength and heat resistance asbestos has been used in wide variety of products and materials including building and construction materials such as insulation, fire retardant, shingles, tiles, drywall, plaster, popcorn ceilings, and cement products.
Asbestos fibers can be released into the air during product use, demolition work, home renovations, repair, and remodeling. Generally, exposure occurs when the asbestos-containing material is disturbed or damaged in some way, allowing the release of asbestos particles and fibers into the air. When inhaled, these particles remain in the lungs and increase your risk of adverse health effects and disease. The most common diseases associated with exposure to asbestos include asbestosis, pleural effusion, mesothelioma and lung cancer.
