Which statement about Full Period CONSECUTIVE Sampling is true?

• A. It uses one sample for the full shift
• B. Two or more samples for the full work shift
• C. It is the least expensive sampling strategy
• D. It is not used to determine exposure

Answer: (B)

Full period consecutive sampling tests the idea that to accurately estimate a worker’s exposure over an entire shift, you need to collect more than one sample in sequence. By taking two or more samples for the full work shift, you capture how exposure changes as tasks shift, controls are used, or environmental conditions vary. This sequence of samples lets you compute a time-weighted average exposure and spot peaks that a single measurement might miss. Because you're collecting multiple samples across the shift, the approach costs more than taking just one sample, so it isn’t the least expensive option. And it’s used precisely to determine exposure, not to avoid it.
