CDPH Lead Inspector/Assessor California State Practice Exam

What is the maximum allowable lead level in the workplace according to OSHA standard?

1. 30 µg/m³

2. 50 µg/m³

3. 60 µg/m³

4. 100 µg/m³

The correct answer is: 50 µg/m³

The maximum allowable lead level in the workplace, according to OSHA standards, is established to ensure the safety and health of workers who may be exposed to lead. The limit is set at 50 µg/m³ (micrograms per cubic meter) for an 8-hour time-weighted average. This regulatory standard is based on extensive research evaluating the health effects of lead exposure, which can lead to serious conditions such as neurological impairment, kidney damage, and high blood pressure. Setting this limit reflects a commitment to minimizing occupational exposure to hazardous substances, thereby protecting workers from the cumulative effects of lead over time. Understanding this threshold is crucial for professionals in occupational safety to implement proper monitoring and protective measures in environments where lead is present.
