Safety第 90 / 100 题
Why is lead exposure a special concern during paint removal on older buildings?
a.Lead dust and chips are toxic, especially to children, and can be inhaled or ingested
b.Lead makes paint dry too slowly
c.Lead improves indoor air quality
d.Lead is only a concern in new construction
解析
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.
