When the GESTIS-ILV database is opened, the substances listed are displayed in alphabetical order, in either grid or list view. This can be selected by means of the button at the top on the right (see Figure 1).
Clicking on the magnifying glass symbol opens the search field, with which a search for a specific substance can be launched. You search using either the CAS number or the substance name. We recommend using the CAS number for searches.
| Tip: The search term must not contain any special characters or spaces. |
To display the limit values for a substance applicable in various countries, search for the substance using the search bar, then click on the appropriate substance in the list of results. A table then opens showing the limit values for the substance in various countries (see Figure 2).
The limit values are stated both as a time-weighted average (TWA) for an eight-hour shift and as a short-term exposure limit (STEL), in each case in ppm, mg/m³ and F/cm³.
Limit values that have changed since the last update are highlighted in yellow. Limit values that have been added recently are highlighted in green (see Figure 3).
The numbers in brackets after the limit value (footnotes) indicate that remarks on this limit value exist (hazard resulting from percutaneous absorption, inhalable fraction, instantaneous value). Clicking on the small downward arrow expands the explanations for the footnotes (see Figure 4).
