Threshold Limit Valve-Time- Weighted Average .( TLV-TWA)

Question

Accepted Answer

TLV-TWA is a safety standard that represents the maximum average concentration of a substance an employee can be exposed to over a specified time period.

TLV-TWA is an abbreviation for Threshold Limit Value-Time-Weighted Average.
It is a safety standard used to determine the maximum average concentration of a substance that an employee can be exposed to over a specified time period, usually 8 hours per day or 40 hours per week.
TLV-TWA is typically expressed in parts per million (ppm) or milligrams per cubic meter (mg/m³).
It helps in assessing and controlling the potential health risks associated with exposure to hazardous substances in the workplace.
For example, if the TLV-TWA for a particular chemical is 5 ppm, it means that an employee should not be exposed to an average concentration of that chemical exceeding 5 ppm over the specified time period.
TLV-TWA values are established by organizations such as the American Conference of Governmental Industrial Hygienists (ACGIH) and are based on scientific research and expert consensus.

Accepted Answer

TLV-TWA:- Time-weighted average concentration for a conventional 8-hour workday and a 40-hour workweak,to which it is believed that nearly all workers may be repeatedly exposed day after day,without adverse effect.
