Scope note: Normas para limitar la exposición de los trabajadores a contaminantes que se encuentran en el aire. Se refieren a la concentración máxima en el aire a la cual se considera que una sustancia particular con exposición diaria repetida no producirá efectos adversos para la salud. Puede ser un promedio ponderado en el tiempo (TLV-TWA, abreviatura de "Threshold Limit Value-Time-Weighted Average"), un valor a corto plazo (TLV-STEL, abreviatura de "Short-Term Value") o un valor instantáneo (TLV-Ceiling). Se expresan como partes por millón (ppm) o miligramos por metro cúbico (mg/m3).

Scope note: Standards for limiting worker exposure to airborne contaminants. They are the maximum concentration in air at which it is believed that a particular substance will not produce adverse health effects with repeated daily exposure. It can be a time-weighted average (TLV-TWA), a short-term value (TLV-STEL), or an instantaneous value (TLV-Ceiling). They are expressed either as parts per million (ppm) or milligram per cubic meter (mg/m3).
