List of chemicals and their Permissible Exposure Limits (PEL) and maximum permissible
concentrations (MPC)
In accordance with Act No. 361/2007 Coll. (Appendix 2, Part A)
(an Amendment to Act No. 178/2001)
MPC: the maximum permissible concentration of a chemical substance in the working environment
PEL: Permissible Exposure Limit (TLV) of the chemical substance, i.e. the maximum permissible value of a time-weighted average (TWA) of
the concentration of a gas in the air.
Explanation of the table:
The "permissible concentrations" box refers to the permissible exposure limits, known as PEL, and the maximum permissible
concentrations, designated as MPC
The " CAS number" box – the registration number of the substance used by Chemical Abstracts Services
The "Notes" box:
I – during exposure the substance penetrates through the skin or a strong irritant effect to the skin occurs.
S – the substance has a sensitising effect.
L – potential significant late effects of the substance are unpredictable.
* - in the case of MPCs pay attention to the physico-chemical properties (e.g. explosiveness).
