What are the two types of air sampling in occupational monitoring?

The correct answer identifies the two prevalent types of air sampling techniques used in occupational monitoring: Personal/Occupational Sampling and Area Sampling.

Personal/Occupational Sampling involves collecting air samples that are directly representative of the exposure an individual worker experiences during their normal activities. This method typically utilizes portable sampling devices that an employee carries, ensuring that the data reflects the actual breathing zone of the worker. This close monitoring is crucial for assessing health risks effectively and implementing necessary protective measures.

Area Sampling, on the other hand, refers to taking air samples from a specified location in the workplace rather than from an individual's personal breathing zone. This method assesses the air quality of a broader environment and can identify the general levels of contaminants present in the workplace atmosphere. It is useful for evaluating whether certain areas exceed accepted exposure limits or guidelines.

Together, these methods provide a comprehensive understanding of air quality in occupational settings, allowing for targeted interventions to minimize worker exposure to hazardous substances.
