Final answer:
Employers are required to provide annual medical exams for workers with blood lead levels at or above 10 micrograms per 100 grams to prevent lead poisoning and comply with health regulations.
Step-by-step explanation:
The employer must provide an annual medical examination to workers whose blood lead level is at or above 10 micrograms per 100 grams.
Exposure to lead can occur through various means such as contaminated air, water, dust, food, or consumer products. Children are especially vulnerable, but adults in high-risk occupations are also at significant risk. The Centers for Disease Control (CDC) has set an action level for blood lead in adults at 10 µg/dl.
It is crucial for employers to monitor blood lead levels in workers and to provide medical examinations if those levels meet or exceed the recommended threshold. This helps in early detection and prevention of lead poisoning, which can have severe health consequences if left untreated. Employers' compliance with health guidelines like these not only ensures the safety of their employees but also aligns with occupational health and safety regulations requiring such monitoring and intervention.
