What is the Excursion Limit (EL) for asbestos?

The Excursion Limit (EL) for asbestos is defined as the maximum allowable concentration of asbestos fibers in the air, measured over a short period of time, typically involving sampling over a 30-minute period. The correct limit set by occupational safety regulations is 1.0 fibers per cubic centimeter (f/cc). This threshold is significant because it helps to protect workers from short-term high exposure levels that could result in serious health risks, such as lung disease or cancer. Understanding and adhering to this limit is crucial for ensuring workplace safety in environments where asbestos may be present.

The other options do not correspond to the established standards for asbestos exposure limits, highlighting the importance of knowing regulatory guidelines in occupational health practices.
