An employee working with lead-based paint removal has a blood lead level of 45 μg/dl. According to Cal/OSHA lead standards, what action must the employer take?
Correct Answer
B) Increase medical monitoring frequency
At 45 μg/dl blood lead level, Cal/OSHA requires increased medical monitoring but removal is not required until 50 μg/dl or higher.
Why This Is the Correct Answer
Under Cal/OSHA lead standards (8 CCR 1532.1), when an employee's blood lead level reaches 40 μg/dl or above, the employer must increase the frequency of medical monitoring from annual to every six months. At 45 μg/dl, this increased monitoring requirement is triggered to closely track the employee's blood lead levels and ensure early detection of any further elevation that could require removal from exposure.
Why the Other Options Are Wrong
Option A: Provide additional training only
Additional training alone is insufficient at this blood lead level. While training is important, Cal/OSHA specifically requires increased medical monitoring frequency when blood lead levels reach 40 μg/dl or above, not just additional training.
Option C: Remove employee from lead exposure
Employee removal from lead exposure is not required until blood lead levels reach 50 μg/dl or higher under Cal/OSHA standards. At 45 μg/dl, the employee can continue working with lead but requires increased medical monitoring.
Option D: No action required
Action is definitely required at 45 μg/dl blood lead level. Cal/OSHA mandates specific responses at various blood lead thresholds, and 45 μg/dl exceeds the 40 μg/dl trigger for increased medical monitoring frequency.
Memory Technique
Remember '40-Monitor More, 50-Stop': At 40 μg/dl increase monitoring frequency, at 50 μg/dl remove from exposure.
