For short, intense exposures, the occupational exposure metric of concern is typically a short-term exposure limit (STEL) or ceiling value. These limits require time-resolved measurements that can capture rapid concentration changes. A photoionization detector (PID) configured for real-time logging at 1-second intervals provides high temporal resolution, allowing the hygienist to evaluate peak concentrations and compute rolling 15-minute averages aligned with STEL criteria. While an 8-hour integrated charcoal tube (Option A) is excellent for TWA evaluation and laboratory confirmation, it masks short-duration peaks by averaging them over many hours. A 2-hour passive badge (Option C) similarly lacks time resolution and may understate peak intensities. An area sample (Option D) does not represent the worker’s breathing zone and can be confounded by spatial variability and ventilation patterns. The best practice is to pair real-time PID screening with task-based personal sampling when possible; for comparison to numeric standards, ensure instrument calibration with an appropriate span gas, apply response factors for specific analytes like toluene, and document sampling start/stop times to align the dataset precisely with the task window.
