How does the calculator work?
The Regulation on Occupational Health and Safety Services sets a minimum monthly time per employee for the workplace physician and the OHS specialist. This time increases with the hazard class. Once your headcount reaches certain thresholds, a full-time assignment is required instead of part-time service.
The calculator applies these rules to your class and headcount. It also shows the renewal frequencies for training, periodic examinations, risk assessment and the emergency plan, as well as the number of members for each emergency team and the number of first aiders.

Frequently asked questions
What are the calculated times based on?
The times for the workplace physician, OHS specialist and other healthcare staff are the minimum monthly times per employee set by the Regulation on Occupational Health and Safety Services. Training, examination, renewal and team ratios are taken from the relevant regulations (see the sources below).
How many visits per month do these times equal?
The regulation sets a total time, not a number of visits. The total is spread across visits during the month according to your shift pattern and the nature of the work; we draw up the plan together at the start of the contract.
I don’t know my hazard class. What should I do?
Your class is determined by the NACE code in your workplace registration with the Social Security Institution (SGK). Enter your code in the quote form and we will confirm your class against the official list.
