The core purpose of the fund is to develop sustainable financial support to ensure the continued existence of ACGIH® TLVs and BEIs. Since its inception the core purpose and ‘cause’ of ACGIH has been to protect workplace employees through the development of science-based occupational exposure guidelines widely known as the TLVs and BEIs.
Threshold limit value − ceiling limit (TLV-C): An absolute exposure limit that should not be exceeded at any time. There are TLVs for physical agents as well as chemical substances. TLVs for physical agents include those for noise exposure, vibration, ionizing and non-ionizing radiation exposure and heat and cold stress.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.

To control an airborne dust, the workplace must first monitor the air for exposures. Typically, concentration of air contaminants is measured and compared to set exposure limits. In the United States, these often follow personal exposure limits (PEL) set by OSHA , or threshold limit values (TLV) set by ACGIH.
Limits for short-term exposure, such as STELs or CVs, are defined only if there is a particular acute toxicity associated with a substance. These limits are set by the American Conference of Governmental Industrial Hygienists (ACGIH) and the Occupational Safety and Health Administration (OSHA), based on experimental data. The values set by ...
