Threshold limit value. This value is the highest permissible
concentration of a working material as a gas, steam or suspended matter
in the air at the working place. According to the present state of knowledge,
this concentration generally does not affect the health of the workers
or cause undue nuisance even with repeated and long-term, as a rule
eight-hour daily effect when observing average weekly working hours.
Apart from practical circumstances of the working processes, the fixing
of threshold limit values above all takes effect characteristics of
the material concerned into account. The decisive elements are scientifically
sound criteria for health protection and not the technical and economic
implementation possibilities in practice.
