True or False: TLV®s are exposure limits set by the EPA.

The statement is false, as TLV®s (Threshold Limit Values) are not established by the Environmental Protection Agency (EPA). Instead, TLV®s are guidelines developed by the American Conference of Governmental and Industrial Hygienists (ACGIH) to indicate the level of exposure to a substance that is believed to be safe for most workers over a particular time period. These values play a crucial role in industrial hygiene and occupational health, guiding employers in setting exposure limits to protect workers.

The EPA, on the other hand, primarily focuses on environmental regulations and standards, including acceptable levels of pollutants in air, water, and soil, but not specifically TLV®s for occupational settings. Understanding this distinction is vital, as it highlights the differences in agencies' roles regarding exposure limits and workplace safety.
