Giải thích
Lead is a potent toxin that damages the nervous system, and children are especially vulnerable to lead dust and chips created during sanding or scraping old paint. This is why the EPA RRP Rule and Cal/OSHA lead standards require containment, safe work practices, and worker protection on pre-1978 buildings. Uncontrolled lead dust endangers both workers and occupants.
