3.1.4.5
occupational exposure limit value
OELV

limit of the time-weighted average of the concentration of a chemical agent in the air within the

breathing zone of a worker in relation to a specified reference period

Note 1 to entry: The term “limit value” is often used as a synonym for “occupational exposure limit value” but

the term “occupational exposure limit value” is preferred because there is more than one limit value (e.g.

biological limit value and occupational exposure limit value).

Note 2 to entry: Occupational exposure limit values (OELVs) are often set for reference periods of 8 h but can

also be set for shorter periods or concentration excursions. OELVs for gases and vapours are stated in terms

independent of temperature and air pressure variables in ml/m and in terms dependent on those variables in

mg/m for a temperature of 20 °C and a pressure of 101,3 kPa. OELVs for airborne particles and mixtures of

particles and vapours are given in mg/m or multiples of that for actual environmental conditions (temperature,

3 3

pressure) at the workplace. OELVs of fibres are given in number of fibres/m or number of fibres/cm for actual

environmental conditions (temperature, pressure) at the workplace.
