Between outsourcing, EU enlargement and globalization, more and more people are working at industrial sites. But before these people can enter the site, they have to be quickly and cost-effectively briefed on basic safety rules. Infraserv Höchst has met this need with ZEUS: a multimedia briefing system for visitors and contractor employees that sets new standards for user friendliness and briefing speed (3 to 5 minutes). An integrated quiz verifies that users have really understood the training material. The self-explanatory, fully automated system can be integrated into ID-management and access-control systems. It also offers the benefit of a flexible, modular design and low maintenance and purchasing costs.
