The Software History
DOHSBase Compare was issued in 1992 for the first time by the committee 'Threshold Values and Measurement Methods' of the Dutch Occupational Hygiene Society (in Dutch: NVvA), who gave the software its current name. The succes of DOHSBase (a second version was developed in 1994) made it preferable to professionalize the future editions. This was not possible within the NVvA charter, so some members of the committee founded DOHSBASE v.o.f. (a limited liability company under Dutch law).
DOHSBASE v.o.f. issued the third edition in 1995 of DOHSBase. In May 1998 the first Windows-version was released (Windows 3.**), which was published alongside the still existing MS-DOS-version: DOHSBase 4. The MS-DOS-version was discontinued in October 1999. In August 2000 DOHSBase was published for the first time as a 32-bitsapplication (for Windows95 and higher) under the name of DOHSBase2000. In May 2005 the beta-version of the Compare Mode was published for the first time (update 2005-01). This enhanced the software to evaluate and compare, besides the regular library of Occupational Exposure Limits and Measurement Methods, all kind of different substances with each other to assess its risks at the workplace atmosphere. The Compare Mode also calculates the so called "Kick-off Values" for substances that do not have any formal occupational exposure limits.
In November 2006 (update 2006-02) the Compare Mode was officially launched and this version of DOHSBase was baptized DOHSBase Compare. Screen languages in English and German were added in this update. The Help function was still in Dutch. During 2008 till 2010 continuous improvement was carried out and screen languages for French, Spanish and Norwegian were added.
In 2011 DOHSBase Compare was made fully REACH compliant (Update 2011-01) and the database was extended from around 4.600 to 172.000 substances. This extension is since then available as the versions NL-Xtend (with focus on the Dutch market) and EU-Xtend (with focus on the international European markets). For the Dutch market the original (with a limited database) is still avalailable as NL Standard.
With the 2012-02 update DOHSBase Compare the Help-file is now fully translated into English.
In July 2013 (update 2013-02) a French and an English version (FR and UK-Xtend) are launched. Also, the European DNELs are included in the table of limit values. In 2014 we discontinued the sale of the (Dutch) NL-Standard version.
From 2019 (update 2019-01) the program will be further developed, maintained and distributed by DOHSBASE BV..
