GESTIS - International limit values for chemical agents
Occupational exposure limits (OELs)
Available as app for iPhone, iPodtouch, iPad and now also as app for Android
This database contains a collection of occupational limit values for hazardous substances gathered from various EU member states, Australia, Canada (Ontario and Québec), Japan, New Zealand, Singapore, South Korea, Switzerland, and the United States as of March 2012. Limit values of about 1,700 substances are listed.
The chemical names of the substances were adopted from the nomenclature as used in the original sources for national limit values. Thus, for retrieval of substances, the use of CAS numbers is strongly recommended. For synonyms of the chemical names given, please refer to e. g. GESTIS substance database.
The present database was elaborated in co-operation with experts from:

Limit values defined by the various expert bodies and authorities differ in the criteria for their derivation, the level of protection which they offer, and their legal relevance. The short-time values and dust fractions may for example be based upon different definitions. Comprehensive explanations can be found in the original lists of limit values, which should be referred to as primary sources. The purpose of this database is merely to provide an overview of the limit values in various countries.
For limit values given in brackets, in bold or italic letters, please note the remarks.
