  1992

  Founded on 13 February 1992

  On 13 February 1992, NVvA chairman Mr. Boers handed the first copy of DOHS-Base to Ms. Mulock Houwer, Director-General for Labour at the Dutch Ministry of Social Affairs. The first release held 1,000+ limit values and measurement methods on a 3.5" or 5.25" MS-DOS diskette.

  Spin-off into DOHSBase v.o.f.

  In 1995 DOHS-Base spun off from the NVvA project into an independent business: DOHSBase v.o.f. (a Dutch general partnership, vennootschap onder firma). Having its own legal identity enabled periodic updates and further development outside the NVvA structure.
