Which statement describes Full Period SINGLE Sampling?

• A. A single sample is taken for the full work shift
• B. Two or more samples are taken for the full shift
• C. It is the most expensive sampling strategy
• D. It directly measures each minute of exposure

Answer: (A)

Full Period SINGLE Sampling means you collect one sample that covers the entire work shift. This single measurement is used to estimate the worker’s average exposure over that shift, giving a simple, lower-cost way to gauge exposure. Because there’s only one data point, it won’t show short-term peaks or minute-by-minute variations, so it’s best when exposures are relatively stable and you’re aiming for a rough time-weighted average. The other options describe either taking multiple samples in the same period, which is a different approach, or imply more detailed or expensive measurements that aren’t what this method provides.
