5.3 Physical, Chemical, and Toxicological Data
for selected Substances
5.3.1 Explanation to the Physical, Chemical,
and Toxicological Data
The table lists physical, chemical and toxicological data for many of the airborne contaminants
that can be measured using direct reading Dräger detector tubes or Dräger-Chips. This table
is intended to serve as a convenient reference source. The information was compiled from
relevant technical publications, however, Dräger is not responsible for any use or misuse
of the information. The given data, especially the threshold limit values, are current as of
AGW-Value: November 2014; TLV-Value: November 2014; WEL-Value: November 2014.
Chemical Name
The common names are given in alphabetical order.
CAS-Number
The CAS-Number is an identification number of the Chemical Abstract Service (CAS).
Chemical Formula
The format is molecular, showing the actual number and kind of atoms.
Molecular Weight
The molecular weight listed in the table is given as Kg/Kmol.
Limit Values
The limit values listed for the gases, vapors and aerosols in the table are given in units
of ml/m 3 (ppm) or mg/m 3 . The ml/m 3 units are given independent of temperature and
pressure, but the mg/m 3 values are based on 20 °C and 1013 hPa (mbar).
German AGW-values 1) : In addition to the 8-hour average of the 40-hour workweek the
limitation of the peak exposure (peak limit / factor of exceeding) is given in line with the
TRGS 900. In case that in the TRGS 900 no values are published then the values of the
DFG list are used (Note "DFG" is used).
With 1) marked values:
Workplace limit values corresponding to the proposed tolerable cancer risk. (see TRGS
900)
With 2) marked values:
Workplace limit vaues corresponding to the proposed preliminary acceptable cancer risk.
