CDPH Lead Inspector/Assessor California State Practice Exam

At what lead exposure level are coveralls typically replaced weekly?

1. 0 - 50 μg/m3

2. 50 - 200 μg/m3

3. More than 200 μg/m3

4. Under 25 μg/m3

The correct answer is: 50 - 200 μg/m3

Coveralls are typically replaced weekly at lead exposure levels ranging from 50 to 200 μg/m3 due to the potential for contamination at these higher levels. At exposure levels in this range, individuals are at an increased risk of lead accumulation on personal protective equipment (PPE), which can lead to inadvertent lead exposure if the contaminated coveralls are not managed properly. The weekly replacement schedule ensures that workers are properly protected while reducing the likelihood of lead particles transferring to skin or other surfaces. This practice is part of effective workplace safety protocols aimed at minimizing lead exposure and maintaining a safe working environment. In contrast, lower exposure levels do not necessitate such frequent changes, as the risk of significant contamination is reduced. Therefore, the standard for coverall replacement is more frequently dictated by the potential for higher concentrations of lead in the workplace atmosphere.
