EC No: European Community (EC) number, the European Union’s numerical identifier for substances.
CAS No: Chemical Abstract Service Registry Number.
A skin notation assigned to the occupational exposure limit value indicates the possibility of significant uptake through the skin.
Measured or calculated in relation to a reference period of eight hours time-weighted average (TWA).
Short-term exposure limit (STEL). A limit value which must not be exceeded. The period to which it relates is 15 minutes, unless otherwise specified.
mg/m³: milligrams per cubic metre of air. For chemicals in gas or vapour phase, the limit value is expressed at 20 °C and 101,3 kPa.
ppm: parts per million by volume in air (ml/m³).
During exposure monitoring, account should be taken of relevant biological monitoring values as suggested by the Scientific Committee on Occupational Exposure Limits for Chemicals Agents (SCOEL).
