Threshold Limit Values (TLVs) are guidelines that indicate the concentration of substances in the workplace air that workers can be exposed to over a specified period without experiencing adverse health effects. The American Conference of Governmental and Industrial Hygienists (ACGIH) is the organization that establishes these TLVs based on scientific research and expert consensus on exposure levels.

ACGIH conducts thorough reviews of the available literature on various substances and their effects on health, allowing them to create these guidelines to promote occupational safety. Understanding TLVs is critical for managing workplace exposure and ensuring the health of workers, as they help inform safety measures and practices.

While the Occupational Safety and Health Administration (OSHA) provides regulations and permissible exposure limits (PELs), and the National Institute for Occupational Safety and Health (NIOSH) conducts research and produces recommendations for workplace safety, TLVs are specifically defined and published by ACGIH. The Environmental Protection Agency (EPA) focuses more on environmental regulations and limits for community exposure rather than workplace conditions.
