What is the purpose of measuring exposure limits like PEL and TLV?

Measuring exposure limits like Permissible Exposure Limits (PEL) and Threshold Limit Values (TLV) serves a critical purpose in assessing the quality of work conditions. These limits are established to protect workers from hazardous substances and ensure that exposure to these substances remains at safe levels. By monitoring and measuring exposure against these established limits, employers can identify potential health risks and implement necessary controls to mitigate such risks.

This assessment plays a key role in promoting a safe and healthy workplace, ultimately contributing to workers' well-being and productivity. In construction and other industries, understanding and managing exposure levels is vital for compliance with occupational safety regulations and maintaining a safe work environment. The other options, while related to workplace dynamics, do not directly pertain to the fundamental objective of measuring exposure limits, which is to ensure safety and health standards are met in the work environment.
