Threshold Limit Value The upper limit of a toxicant concentration to which an average, healthy person may be exposed all day, every day, without suffering adverse effects
Threshold Limit Value indicates the concentration of a chemical substance in the atmosphere that is considered non-hazardous in a person's normal working life

Threshold Limit Value An eight hour time weighted average level at which the majority of employees may be exposed to without undue health effects Established by the ACGIH
Threshold Limit Value, an exposure limit recommended by the ACGIH (see "What are exposure limits?", Understanding Toxic Substances)
Threshold Limit Values set by a private industrial hygiene organization TLVs are updated each year based on new health hazard and chemical research TLVs are equivalent to PELs, but TLVs are more current
Threshold Limit Value; The airborne concentration of a substance to which nearly all workers may be exposed without adverse health effects; set by the American Conference of Government Industrial Hygienists (ACGIH)
Threshold Limit Value Concentration of gases in air to which it is believed personnel may be exposed 8 hours per day or 40 hours per week throughout their working life without adverse effects The basic TLV is a Time Weighted Average (TWA) and may be supplemented by a TLV-STEL (Short Term Exposure Limit) or TLV-C (Ceiling exposure limit which should not be exceeded even instantaneously)
Threshold Limit Value: A term used by ACGIH to express the airborne concentration of a material to which nearly all persons can be exposed day after day without adverse effects ACGIH expresses TLVs in three ways: TLV-TWA: The allowable Time-Weighted Average concentration for a normal 8-hour workday or 40-hour week TLV-STEL: The Short-Term Exposure Limit or maximum concentration for a continuous exposure period (maximum of four such periods per day, with at least 60 minutes between exposure periods, and provided that the daily TLV-TWA is not exceeded) TLC-C: The Ceiling Exposure Limit - the concentration that should not be exceeded even instantaneously See also "Skin "
An exposure level under which most people can work consistently for 8 hours a day, day after day, with no harmful effects
Threshold limit value, the time weighted average concentration of an airborne substance that represents the condition under which workers may be exposed in a normal eight hour day, five day work week without suffering adverse effect
