What is the range for personal air sampling rates in liters per minute?

The appropriate range for personal air sampling rates in liters per minute typically falls between 0.5 to 5 liters per minute. This range is effective for accurately capturing airborne particles, including asbestos fibers, ensuring that the samples are representative of the actual exposure levels experienced by a worker.

Sampling rates that are too low may not capture sufficient airborne contaminants, while rates that are too high can risk losing smaller particles through inertial deposition or other sampling artifacts. Therefore, a rate within the specified range balances the need for effective sampling while minimizing the potential for collection errors. This is particularly critical in environments where hazardous materials like asbestos are present, as accurate monitoring is essential for ensuring worker safety and compliance with health standards.
