CDPH Lead Inspector/Assessor California State Practice Exam

When performing a Class III Trigger Task, what can you assume about the working conditions?

1. Below the PEL

2. At the PEL

3. Above 10 times the PEL

4. Above 50 times the PEL

The correct answer is: Above 50 times the PEL

In a Class III Trigger Task, lead exposures are generally anticipated to be significant, often indicating that the working conditions could exceed permissible exposure limits (PEL). This classification typically applies to activities that are expected to cause disturbance of lead-containing materials, leading to higher dust levels in the work environment. When the working conditions are described as above 50 times the PEL, it highlights the need for stringent safety measures and monitoring due to the serious risk posed to workers. The assumption that levels are this high necessitates the implementation of protective measures such as respiratory protection, engineering controls, and strict hygiene protocols to mitigate the potential for lead exposure. In contrast, other options suggest varying degrees of compliance with exposure limits that do not pertain to the hazardous nature of a Class III Trigger Task. Therefore, the correct assumption of conditions being above 50 times the PEL underscores the critical awareness required in these high-exposure settings and aligns with the nature of the work done during such tasks.
